ammonium phosphate is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid with liquid ammonia. Calculate the moles of ammonium phosphate produced by the reaction of 2.4 mol of ammonia. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.
Answers
Answer:
0.57 moles (NH4)3PO4 (2 sig. figs.)
Explanation:
To quote, J.R.
"Note: liquid ammonia (NH3) is actually aqueous ammonium hydroxide (NH4OH) because NH3 + H2O -> NH4OH.
H3PO4(aq) + 3NH4OH(aq) ==> (NH4)3PO4 + 3H2O
Assuming that H3PO4 is not limiting, i.e. it is present in excess
1.7 mol NH4OH x 1 mole (NH4)3PO4/3 moles NH4OH = 0.567 moles = 0.57 moles (NH4)3PO4 (2 sig. figs.)"

What is the average atomic mass for element Z?
Average atomic mass of Z = [mass]
Answers
Answer:
Average atomic mass = 19.9 amu
Explanation:
Isotopes can be defined as two or more forms of a chemical element that are made up of equal numbers of protons and electrons but different numbers of neutrons.
Generally, the isotopes of a chemical element have the same chemical properties because of their atomic number but different physical properties due to their atomic weight (mass number).
Given the following data;
Relative abundance of Z-19 = 55%
Relative abundance of Z-21 = 45%
Atomic mass of Z-19 = 19 amu
Atomic mass of Z-21 = 21 amu
To find the average atomic mass;
Average atomic mass = 19 * (55/100) + 21 * (45/100)
Average atomic mass = 19*0.55 + 21*0.45
Average atomic mass = 10.45 + 9.45
Average atomic mass = 19.9 amu
Therefore, the average atomic mass for element Z is 19.9 amu.
Why KHPo4 ignore effective as a buffer but kh2po4 is not
Answers
KH2PO4 is a more suitable choice as a buffer because it has a greater buffering capacity due to the presence of the weak acid and its conjugate base.
KHPo4 is not considered an effective buffer compared to KH2PO4 due to its limited buffering capacity. The effectiveness of a buffer is determined by the concentration and dissociation properties of its conjugate acid-base pair.
KH2PO4 is a salt composed of the weak acid H2PO4- and its conjugate base HPO4^2-. In an aqueous solution, KH2PO4 can dissociate to release H+ ions from the H2PO4- component, which acts as a weak acid, and the HPO4^2- component can accept H+ ions, acting as a weak base. This allows KH2PO4 to effectively resist changes in pH when small amounts of acid or base are added to the solution.
On the other hand, KHPo4 consists of the strong acid H3PO4 and the weak base HPO4^2-. H3PO4 fully dissociates in water, providing a large concentration of H+ ions, making it difficult for the HPO4^2- to effectively act as a base and maintain pH stability.
Therefore, KH2PO4 is a more suitable choice as a buffer because it has a greater buffering capacity due to the presence of the weak acid and its conjugate base.

What is the Equator line?The Equator line at zero (0) latitude is an imaginary line that divides the Earth's planet into two equal parts composed of South latitudes and North latitudes.
Temperatures at low latitudes, i.e., near the Equator line, are warmer because this region receives perpendicular solar rays all the year, thereby the energy of solar radiation is distributed to the Earth's surface.

A 150-lb patient is prescribed acetaminophen at 7.34 mg/kg. If acetaminophen is available on hand as a 0.125 mg/ml syrup, how many mililiters will the nurse administer?
Answers
Answer:
The nurse should administer 3995.2 millilitres of syrup.
Explanation:
The conversion factor of pound weight to kilogram is; 1 lb = 0.453592 kg
The body weight of the patient in Kg = 150 * 0.453592 = 68.04 kg
A prescription of 7.34 mg/kg acetaminophen means that he should receive;
7.34 mg * 68.04 = 499.4 mg of acetaminophen
Amount in grams of acetaminophen per millilitre of syrup = 0.125 mg
Number of millilitres of syrup required = 499.4 mg / 0.125 mg/mL = 3995.2 mL
Therefore, the nurse should administer 3995.2 millilitres of syrup.

How many mL of this suspension should be given to an infant weighing 17 lb ? (Assume two significant figures.)
Express your answer using two significant figures.
Answers
The amount, in mL, of the suspension that should be given to an infant weighing 17 lb will be 1.16 mL
Dimensional analysis0.8 mL of the liquid contains 80.0 mg of the drug.
The recommended dose is 15 mg per kg of body weight
The infant to be given the drug weighs 17 lb.
First, let's convert the weight of the infant to kg.
1 lb = 453.59 g
17 lb = 453.59 x 17/1
= 7711.03 g
1000 g = 1 kg
7711.03 g = 7711.03 x 1/1000
= 7.711 kg
So, the baby's weight is 7.711 kg.
The drug dose for the baby can thus be calculated as:
15 mg x 7.711 = 115.67 mg
But 0.8 mL of the drug contains only 80.0 mg. How many mL will contain 115.67 mg?
0.8 x 115.67/ 80.0 = 1.16 mL

Explanation:
First, let's see the mass percent (% w/w) formula:
\(Percent\text{ by mass=}\frac{mass\text{ }of\text{ }solute}{mas\text{s of solution}}\cdot100\%.\)The problem is telling us that we have a solution with a mass of 336.6 g and its percent by mass is 23.48 % w/w and they are asking us to find the mass of sugar, which in this case, sugar is the solute.
To answer this problem, we have to solve for 'mass of solute' and replace the given data, as follows:
\(\begin{gathered} Mass\text{ of solute=}\frac{percent\text{ by mass}\cdot mass\text{ of solution}}{100\%}, \\ \\ Mass\text{ of solute=}\frac{23.48\%\cdot336.6\text{ g}}{100\%}, \\ \\ Mass\text{ of solute=79.03 g.} \end{gathered}\)The answer would be that we require 79.03 g of sugar.

In the combustion of hydrogen gas, hydrogen reacts with oxygen from the air to form water vapor. hydrogen+oxygen⟶water
If you burn 46.2g of hydrogen and produce 413g of water, how much oxygen reacted?
mass of oxygen:
Answers
Answer:
ok, here is your answer
Explanation:
AI-generated answer
To find the mass of oxygen that reacted, we need to use the Law of Conservation of Mass, which states that in a chemical reaction, the mass of the reactants equals the mass of the products.
First, we need to find the number of moles of hydrogen that reacted:
Molar mass of hydrogen (H₂) = 2.016 g/mol
Number of moles of H₂ = mass/molar mass = 46.2 g/2.016 g/mol = 22.92 mol
Next, we need to use the balanced chemical equation to find the number of moles of water produced:
hydrogen + oxygen → water
2H₂ + O₂ → 2H₂O
From the equation, we can see that for every 2 moles of H₂, 1 mole of O₂ is required to produce 2 moles of H₂O. Therefore, the number of moles of O₂ required to produce 22.92 moles of H₂O is:
Number of moles of O₂ = 1/2 x 22.92 mol = 11.46 mol
Finally, we can find the mass of oxygen that reacted by using its molar mass:
Molar mass of oxygen (O₂) = 32.00 g/mol
Mass of oxygen = number of moles x molar mass = 11.46 mol x 32.00 g/mol = 366.72 g
Therefore, the mass of oxygen that reacted is 366.72 g.

It's important to note that at complete neutralization, the pH of the solution will not be equal to

Answers
Answer:
X(HCO3)2 is X2(C2H2O6), so the total number of atoms for each element can be calculated:
2 X atoms
4 H atoms
6 C atoms
12 O atoms
Calculate the total atomic mass of the elements:
2 X atoms * atomic mass of X = 2X * atomic mass of X
4 H atoms * 1.0 amu = 4.0 amu
6 C atoms * 12.0 amu = 72.0 amu
12 O atoms * 16.0 amu = 192.0 amu
The molar mass of X(HCO3)2 is 162 g/mol, so the total atomic mass of the elements should add up to 162 g/mol:
2X * atomic mass of X + 4.0 amu + 72.0 amu + 192.0 amu = 162 g/mol
Solve for X by rearranging the equation:
2X * atomic mass of X = 162 g/mol - 4.0 amu - 72.0 amu - 192.0 amu = -12.0 amu
2X = -12.0 amu / atomic mass of X
Divide both sides by 2:
X = -6.0 amu / atomic mass of X
So the relative atomic mass of X is 6.0 amu.
