what is the electron configuration of br if it loses three electrons?
Answers
The electron configuration of Br if it loses three electrons is [Ar] 3d10 4s2 4p2. In order to answer this question, we first have to determine the electron configuration of bromine Br.
The electron configuration of bromine (Br) is [Ar] 3d10 4s2 4p5, where [Ar] represents the electron configuration of the noble gas argon. This means that bromine has seven valence electrons in its outermost shell. If it loses three electrons, it will have four valence electrons left.
The electron configuration of Br if it loses three electrons is therefore [Ar] 3d10 4s2 4p2.This is because the loss of three electrons would result in the loss of all of the electrons in the 4p subshell, leaving only the electrons in the 3d and 4s subshells.

Which of the following statements about buffers is false? a) a buffer resists changes in pH upon addition of small amounts of strong acids and bases b) a buffer solution can react with either HjOor OH ions c) a buffer solution resists change in pH upon small dilutions d) a buffer always consists of a weak acid and a soluble ionic salt of the weak acid e) most body fluids contain natural buffer systems
Answers
The false statement about buffers is: d) a buffer always consists of a weak acid and a soluble ionic salt of the weak acid.
Buffers are solutions that can resist changes in pH when small amounts of acids or bases are added. They typically consist of a weak acid and its conjugate base (or a weak base and its conjugate acid). The weak acid and its conjugate base are present in equilibrium, allowing the buffer to accept or donate protons to maintain a relatively constant pH. Option d is false because a buffer can consist of a weak acid and its conjugate base, or a weak base and its conjugate acid. It is not necessary for a buffer to always include a soluble ionic salt.

Answers
(a) Carbon monoxide (CO) emissions from internal combustion engines increase in colder climates. Thus, the environmental damage from CO emissions is worse in the winter months than in the summer months.
Nonetheless, air quality control authorities use a standard for CO that is uniform throughout the year with no allowance for seasonal effects. Suppose you are in charge of setting a policy for CO emissions. The marginal damages cost (MD) in the winter is 3E and in the summer is 2E. The MAC of CO emissions in both winter and summer is 60-E. To ensure an allocatively efficient outcome across the two seasons, the marginal damage cost (MD) and the marginal abatement cost (MAC) should be equal. At the point where MD=MAC, social welfare will be maximized. Therefore, equating marginal damage cost (MD) and marginal abatement cost (MAC) in both winter and summer gives: 3E = 60 - E2E = 60 - EE = 20. Thus, the government should set a uniform CO emission standard for winter and summer seasons at 20 to ensure an allocatively efficient outcome across the two seasons.
(b) If the government sets a policy that says emission level for winter and summer will be equiproportion, i.e., E = 15, determine the change in net benefit or welfare loss associated with this policy. MD of CO emission in winter = 3E = 3(15) = 45MD of CO emission in summer = 2E = 2(15) = 30 MAC of CO emission in both winter and summer = 60 - E = 60 - 15 = 45. For a policy that says emission level for winter and summer will be equiproportion, the level of CO emission will be E = 15. The corresponding net benefit can be found as: NB = MB - MC = (MD - MAC) * E = (45 - 45) * 15 = 0. Therefore, the net benefit or welfare loss associated with this policy is zero.

2. An archer shoots three arrows at a target and each land within 1 cm of the others but none of the arrows is within 30 cm of the bull's eye. Discuss both the accuracy and the precision of the archer.
Answers
Answer:
Accuracy refers to how close the arrows are to the bull's eye, while precision refers to how close the arrows are to each other.
In this scenario, the archer's shots are precise but not accurate. The arrows are all within 1 cm of each other, which shows that the archer's shots are consistent and repeatable, but none of the arrows are within 30 cm of the bull's eye. This means that the archer's shots are accurate to a certain extent, but not accurate enough to hit the bull's eye.
To improve the accuracy of the archer, he/she could practice aiming at the bull's eye, and focusing on form and technique. The archer could also get feedback from a coach or mentor to understand what might be causing the arrows to land away from the bull's eye.
On the other hand, the archer's precision is good, and this can be maintained by regular practice and fine-tuning the aim and form. The archer should aim to keep the consistency of the shots and keep the arrows close to each other.
A saturated solution of BaSO4, at 25°C was found experimentally to have a concentration of 4.0 x 10^-5 mol dm^-3. What is the solubility product of this salt?
Answers
The solubility product (Ksp) of the salt given in question is 1.6x10^-9.
What is solubility product?
The equilibrium constant for a solid material dissolving in an aqueous solution is the solubility product constant, Ksp. It stands for the degree of solute dissolution in solution. A substance's Ksp value increases with how soluble it is.
Suppose we have reaction:
aA(s)↽⇀cC(aq)+dD(aq)
So, the formula to determine solubility product will be:
\(K_{sp} = [C]^c[D]^d\)
Let S mol/L be the solubility of salt. So,
\(S = [BaSo_4] = [Ba^{2+}] = [So_4^{2-}]\)
\(S = 4.0\times10^{-5}\)
we know that,
\(K_{sp} = [C]^c[D]^d = S\times S\)
\(K_sp = (4.0\times10^{-5}) \times (4.0\times10^{-5})\)
\(K_sp = 1.6 \times 10^{-9}\)
Hence, the solubility product is \(1.6 \times 10^{-9}\).

(A) MgX
(B) Mg2X
(C) MgX2
(D) Mg3X2
Answers
The compound most likely formed with magnesium, Mg, is MgX . The correct option is (A) MgX.
The electronic configuration of the element, X is 2,8,7. Since X is located in group 7 of the periodic table, it has 7 electrons in its valence shell. In order to obtain a stable configuration, the atom can either gain one electron to fill the 3rd energy level completely or lose seven electrons to completely empty the 2nd energy level, which is easier. The resulting ion, X-, would have a stable electronic configuration of 2,8. Hence, the compound most likely formed with magnesium, Mg, is MgX .The correct option is (A) MgX.
Explanation: Magnesium is located in group 2 of the periodic table and has two valence electrons in its outermost shell. It loses these two electrons to form Mg2+ ions with stable electronic configurations of 2,8. On the other hand, element X gains an electron to form X- ions with stable electronic configurations of 2,8.The combination of Mg2+ and X- ions results in the formation of the compound MgX with a neutral charge.

which reagent (reactant) is limiting when 1.85 mol of sodium hydroxide and 1.00 mol carbon dioxide are allowed to react? how many moles of sodium carbonate can be produced? how many moles of the excess reactant remain after the completion of the reaction?
Answers
In the given chemical reaction \(\rm NaOH + CO_2 \rightarrow Na_2CO_3 + H_2O\), the limiting reagent is carbon dioxide and \(\rm Na_2CO_3\) that can be produced is 1.00 mol, and 0.85 mol of NaOH remains unreacted after the completion of the reaction.
The limiting reagent is the reactant that gets completely consumed in a chemical reaction, thereby limiting the amount of product that can be formed.
The balanced chemical equation for the reaction between sodium hydroxide and carbon dioxide is:
\(\rm NaOH + CO_2 \rightarrow Na_2CO_3 + H_2O\)
To determine which reactant is limiting, we need to calculate the number of moles of sodium hydroxide and carbon dioxide present and compare the mole ratios of the reactants in the balanced equation.
Moles of NaOH = 1.85 mol
Moles of \(\rm CO_2\) = 1.00 mol
The balanced equation shows that the mole ratio of NaOH to \(\rm CO_2\) is 2:1, which means that 2 moles of NaOH react with 1 mole of \(\rm CO_2\) .
Using the mole ratio, we can calculate the maximum number of moles of Na2CO3 that can be produced by each reactant:
Moles of NaOH / 2 = 0.925 mol \(\rm Na_2CO_3\)
Moles of\(\rm CO_2 \times 1\) /1 = 1.00 mol \(\rm Na_2CO_3\)
Since the calculated number of moles of \(\rm Na_2CO_3\) from \(\rm CO_2\) is less than the calculated number of moles of \(\rm Na_2CO_3\) from NaOH, \(\rm CO_2\) is the limiting reactant.
According to the balanced equation, 1 mole of \(\rm CO_2\) reacts to form 1 mole of \(\rm Na_2CO_3\) . Therefore, the number of moles of \(\rm Na_2CO_3\) produced is 1.00 mol.
To determine the amount of excess reactant remaining after the reaction, we need to calculate the amount of NaOH that did not react.
Moles of NaOH remaining = Moles of NaOH - (Moles of \(\rm Na_2CO_3\) produced x 2)
= 0.85 mol NaOH
Therefore, 0.85 mol of NaOH remains unreacted after the completion of the reaction.
In conclusion, carbon dioxide is the limiting reactant, and 1.00 mol of \(\rm Na_2CO_3\) can be produced. 0.85 mol of NaOH remains unreacted after the completion of the reaction.

Hydroxylamine nitrate contains 29.17 mass % N, 4.20 mass % H, and 66.63 mass % O. Determine its empirical formula.
Answers
Answer:
the empirical formula is \(H_2NO_2\)
Explanation:
The empirical formula is
The following information is given
It contains 29.17 mass percentage of N
4.20 mass percentage of H
And, 66.63 mass percentage of 0
Now based on the above information, the empirical formula is \(H_2NO_2\)
hence, the same is to be considered and relevant too
Considering the definition of empirical formula, the empirical formula is H₂N₁O₂= H₂NO₂
The empirical formula is the simplest expression to represent a chemical compound, which indicates the elements that are present and the minimum proportion in whole numbers that exist between its atoms, that is, the subscripts of chemical formulas are reduced to the most integers small as possible.
Hydroxylamine nitrate contains 29.17 mass % N, 4.20 mass % H, and 66.63 mass % O.
Assuming a 100 grams sample, the percentages match the grams in the sample. So you have 29.17 grams of N, 4.20 grams of H and 66.63 grams of O.
Then it is possible to calculate the number of moles of each atom in the molecule, taking into account the corresponding molar mass:
N:\(\frac{29.17 grams}{14 \frac{grams}{mole} }\)= 2.08 molesH:\(\frac{4.20 grams}{1 \frac{grams}{mole} }\)= 4.20 molesO:\(\frac{66.63 grams}{16 \frac{grams}{mole} }\)= 4.16 molesThe empirical formula must be expressed using whole number relationships, for this the numbers of moles are divided by the smallest result of those obtained. In this case:
N:\(\frac{2.08 moles}{2.08 moles}\)= 1H:\(\frac{4.20 moles}{2.08 moles}\)= 2.02 ≅ 2O:\(\frac{4.16 moles}{2.08 moles}\)= 2Therefore the H: N: O mole ratio is 2: 1: 2

5. How many hydrogen atoms are in 1 gallon of octane?
Density of octane= 0.7028 g/mL, 3780 mL = 1 gal
Answers
The chemical formula for octane, C8H18, is an alkane and a hydrocarbon. Its condensed structural formula is CH3(CH2)6CH3. The amount and location of branching in the carbon chain determine the various structural isomers of octane.
Carbon is represented by the letter C, octane by the formula C8H18. As a result, there will be 8 moles of carbon for every mole of C8H18.
Utilizing the molar mass of octane, convert 20 kg of octane to moles of octane.
Octane's molar mass is calculated as (8*12.011)+(18*1.008)=114.23 g/mole, where 8 and 18 are the molecule's atoms and 12.011 and 1.008 are the carbon and hydrogen atoms' individual molar masses.
20kg C8H18*1000g/kg*mole
C8H18/114.23g C8H18 = 175.1 moles of octane.
Put that quantity of moles into moles of carbon now:
1400.8 mole C is equal to 175.1 mole C8H18 * (8 mole C/mole C8H18).
Now keep in mind that a mole of a specific element equals 6.022*1023 atoms.
As a result, your final answer of 8.4*1026 atoms, or 1400.8 mole C, is identical to 1400.8*(6.022*1023) atoms C.

Rainwater is considered soft water because it is naturally low in mineral content - specifically calcium and magnesium ions - which are the ions that make water hard. As rainwater falls, it does not come into contact with the ground or rocks long enough to pick up significant amounts of these ions. Therefore, it retains its softness. However, as rainwater flows on the ground, it can collect minerals that can make it harder.
