Part A What kind of bond forms during the dehydration synthesis of two amino acids, and which functional groups are involved
Answers
During the dehydration synthesis of two amino acids, a peptide bond is formed, and the functional groups that are involved are the carboxyl group (-COOH) and amino group (-NH2).
Dehydration synthesis is a chemical reaction that is also known as a condensation reaction. The reaction involves combining two monomers or small molecules into a large molecule, and it occurs with the elimination of a water molecule. Dehydration synthesis is the reverse of hydrolysis. During dehydration synthesis, two amino acids combine to create a peptide bond, which is also known as an amide bond.
The carboxyl group of one amino acid reacts with the amino group of the other amino acid. This reaction leads to the removal of a water molecule, and the formation of a peptide bond between the two amino acids.In conclusion, a peptide bond is formed during the dehydration synthesis of two amino acids, and the functional groups that are involved are the carboxyl group (-COOH) and the amino group (-NH2).

What is ionic bond?The main contact that takes place in ionic compounds is called ionic bonding, and it involves the electrostatic attraction between two atoms or ions with dramatically differing electronegativities. Along with covalent and metallic bonds, it is one of the most prevalent types of bonds. Ions are atoms, or collections of atoms, that have an electrical charge. Ions with a negative charge are produced by gaining electrons in atoms (called anions). Ions with a positive charge are created when atoms lose their electrons (called cations).
Electrovalence, as opposed to covalence, is the name for this transfer of electrons. The cation is a metal atom in the most straightforward scenario, while the anion is a nonmetal atom, however these ions can have more complex chemical compositions.

A chemist is studying the rate of the Haber synthesis: N2 + 3H2 2NH3
Starting with a closed reactor containing 1. 25 mol/L of N2 and 0. 50 mol/L of H2, the chemist finds that the H2 concentration has fallen to 0. 25 mol/L in 44 seconds. What is the N2 concentration after 44 seconds?
Answers
The concentration of the nitrogen after 44 seconds is 0.0175 mol/L.
What is the concentration of the nitrogen after 44 second?We know that the rate of reaction has to do with how fast or slow that the reaction is progressing. If the reaction is not progressing that fast we could say that the rate of reaction is slow but if the reaction is moving on quite fast we could say that the rate of the reaction is fact.
Having said this, we can see that the reaction that we have here is the Haber process and it involves the combination of the hydrogen and the nitrogen to form the product of the reaction.
Rate of consumption of hydrogen = 0. 25 mol/L - 0. 50 mol/L /44 s
= -5.68 * 10^-3 mol/Ls-1
For the nitrogen molecule we would now have;
3/2 * -5.68 * 10^-3 = M - 1.25/44
Let M be the final concentration of the nitrogen
-8.5* 10^-3 + 0.026 = M

What volume in (L) of N2 would be produced if 143 g of NaN3 completely reacted at STP?
Answers
INFORMATION:
We know that:
- An automobile airbag inflates when NaN3 is converted to Na and N2 gas according to the equation,
2NaN3 → 2 Na + 3 N2.
And we must find the volume in (L) of N2 if 143 g of NaN3 completely reacted at STP
STEP BY STEP EXPLANATION:
To find it, we need to work with the conditions as an ideal gas.
The ideal gas equation is
\(PV=nRT\)1. We must find n:
To find n, we must first divide the 143 g of NaN3 by the molar mass
\(\frac{143g}{65\frac{g}{mol}}=2.2mol\)So, we have 2.2 mol of NaN3
Now to find n, we must multiply the number of mol of NaN3 by the relation between NaN3 and N2
\(2.2mol\text{ }NaN_3\times\frac{3mol\text{ }N_2}{2mol\text{ }NaN_3}=3.3mol\text{ }N_2\)Then, n = 3.3 mol
2. using STP conditions:
- T = 273K
- P = 760 torr
And using R = 62.36 (L*torr)/(K*mol)
Finally, replacing in the ideal gas equation solver for V
\(V=\frac{nRT}{P}=\frac{3.3mol\times62.36\frac{L\cdot torr}{K\cdot mol}\times273K}{760torr}=73.92L\)So, 73.92 L of N2 would be produced if 143 g of NaN3 completely reacted at STP.
ANSWER:

why are all of the elements in group 18 relatively unreactive whereas those in group 17 are reactive
Answers
Because they only require one electron to form an octet
What is octet?
The existence of 8 electrons in an atom's outermost shell indicates that the atom is stable and has the electron configuration of an inert gas.
Every atom wants to be stable, therefore they combine with one another to reach the octet state by gaining, losing, or sharing electrons.
According to the electronic theory of chemical bond formation, atoms can unite by passing, that is, gaining or losing valence shell electrons from one element or atom to another, or by dividing or sharing them to achieve a complete octet in their final shells. The octet rule is what it's called.
The rule of eight, electronic theory of valence, and octet theory of valence are all names for the octet rule. According to the octet theory:
Atoms interact with one other by losing, gaining, or sharing electrons during the creation of a chemical bond. They do, however, develop a stable outermost shell of eight electrons.
Elements in Group 18 have complete outer energy levels and do not easily form ions. Because they only require one electron to create an octet, Group 17 elements are highly reactive.

Answers
Answer:
Powerade has the most dissolved ions, followed by Gatorade and lastly vitamin water
Explanation:
How conductive a certain solution is, is based on the kind of ions that are present or dissolved in the solution. Hence, we have it that, the higher the concentration of the ions that are present in a solution, the better it will conduct.
There is thus, a direct relationship between what is dissolved or the kind of present ions and how conductive the solution is.
A solution with more dissolved ions is a better conductor of electricity and thus has a conductivity value that is higher
Thus, we can conclude that Powerade has more dissolved ions, Gatorade has less and Vitamin water has the least

Hydrogen shows properties of both metals and nonmetals. However, hydrogen is placed with the alkali metals since it contains one valence electrons.
What is hydrogen ?Hydrogen is the first element in the periodic table. It has only one electron and it is the valence electron of hydrogen. Therefore, hydrogen is placed in the first group of periodic table.
Hydrogen needs one more electrons to become stable. The 17th group elements halogens also have a valency of one. Hence, hydrogen shows some chemical similarities with halogens also.
Mostly hydrogen forms covalent bonds like non-metals and in rare cases, hydrogen forms ionic bonds by donating its electron. Therefore, hydrogen is mostly considered as a non-metal.

tap water is often fluoridated with a sodium fluoride (naf) concentration of approximately 1 ppm. if you consume 0.8 kg of tap water per day, how many grams of naf do you consume?
Answers
If you consume 0.8 kg of tap water per day, you can consume 0.0008 g (or 0.8 mg) of NaF.
Tap water is fluoridated with a sodium fluoride (NaF) concentration of approximately 1 ppm.
1 ppm means 1 part of NaF per million parts of water (by mass).
Therefore, in 1 kg (1000 g) of tap water, there would be 1 mg of NaF.
So, in 0.8 kg (800 g) of tap water, the amount of NaF consumed would be:
(1 mg NaF / 1 kg of water) x (800 g of water) = 0.8 mg NaF
To convert milligrams (mg) to grams (g), we divide by 1000:
0.8 mg NaF / 1000 = 0.0008 g NaF
Therefore, you would consume 0.0008 g (or 0.8 mg) of NaF per day.

When Lulu reaches to put this test tube of acid into the beaker along with test tube of base she accidentally knocks the test tubes together hard enough to break them and their respective contents combine in the bottom of the beaker. Is the solution formed from the contents of the two test tubes acidic or basic? What is the pH of the resulting solution?
Answers
Answer:
The solution formed is acidic
pH = 0.87
Explanation:
The acid-base reaction of NaOH with HCl is:
NaOH + HCl → NaCl + H₂O
Where 1 mole of NaOH reacts with 1 mole of HCl
In the problem, moles of NaOH and HCl are:
NaOH: 0.0250L × (0.525mol / L) = 0.013125 moles NaOH
HCl: 0.0750 × (0.355mol / L) = 0.026625 moles HCl
As moles of HCl > moles NaOH, HCl is in excess and the solution formed is acidic
Moles in excess of HCl are:
0.026625 moles - 0.013125 moles = 0.0135 moles HCl
As the volume of the solutions is 25.0mL + 75.0mL = 100.0mL = 0.100L, molarity of HCl after reaction is:
0.0135 moles HCl / 0.100L = 0.135M HCl = 0.135M H⁺
As pH is defined as - log [H⁺], pH of the solution is:
pH = -log 0.135M H⁺ = 0.87
pH = 0.87
The pH of the resulting solution of the acid and base mixture is; Acidic with a PH = 0.87
We are given;
Volume of NaOH = 25 mL = 0.025 L
Volume of HCl = 75 mL = 0.075 L
Concentration of NaOH = 0.525 M
Concentration of HCl = 0.355 M
Total volume of solution = 0.025 + 0.075 = 0.1 L
Now, the the equation of the reaction is;
HCl + NaOH = NaCl + H2O
We can see that 1 mole of HCl reacts with 1 mole of NaOH.
Since; number of moles = Volume × concentration
Number of moles of HCl = 0.075 × 0.355
Number of moles of HCl = 0.026625 moles
Similarly;
Number of moles of NaOH = 0.025 × 0.525
Number of moles of NaOH = 0.013125 moles
We can see that the number of moles of HCl is greater than that of NaOH and as such there is excess HCl acid in the mix.
Thus,
Excess moles of HCl acid = 0.026625 - 0.013125
Excess moles of HCl acid = 0.0135 moles
Concentration of this excess HCl is gotten by the formula;
M = Excess moles/total volume
M = 0.0135/0.1
M = 0.135 M
PH of this excess concentration is;
PH = -log [H+]
PH = -log [0.135]
PH = 0.87
