In which pair would both compounds have the same empirical formula? A. H2O and H2O2 B. BaSO4 and BaSO3 C. FeO and Fe2O3 D. C6H12O6 and HC2H3O2

Answers

Answer 1

Answer: The pair of both compounds that have the same empirical formula are C6H12O6 and HC2H3O2. The answer is letter D. H2O and H2O2, BaSO4 and BaSO3 and FeO and Fe2O3 do not have the same empirical formula.

Use the periodic table to find the charge of the ion that each atom is most likely to form. The charge of a sulfur (S) ion is The charge of a potassium (K) ion is The charge of a boron (B) ion is The charge of an iodine (I) ion is The charge of a bromine (Br) ion is

Answers

Final answer:

The charges of ions that Sulfur (S), Potassium (K), Boron (B), Iodine (I), and Bromine (Br) are most likely to form are -2, +1, +3, -1, and -1, respectively. This is determined by their positions on the periodic table.

Explanation:

The charge of an ion that a certain atom is most likely to form is dependent on its position on the periodic table. Elements on the left side of the periodic table (like potassium) tend to lose electrons and form positive ions, while elements on the right side (like sulfur, iodine, bromine) tend to gain electrons and form negative ions.

The charge of a sulfur (S) ion is usually -2 because sulfur, being in Group 16, tends to gain two electrons to reach a stable electronic configuration. The charge of a potassium (K) ion is usually +1. This is because potassium, which is in Group 1, usually loses one electron to achieve a stable electron configuration. The charge of a boron (B) ion is usually +3 because boron, being in Group 13, tends to lose three electrons in order to reach stability. The charge of an iodine (I) ion is usually -1 because iodine, which is in Group 17, tends to gain one electron to reach stability. Lastly, the charge of a bromine (Br) ion is usually -1, because bromine, also in Group 17, tends to gain one electron to attain a stable electronic configuration.

Bromine (Br) is -1

Explanation:

Why are some elements more reactive than others?

Answers

All other atoms have less stable electron numbers, so they react with each other and share electrons to be more stable. The most reactive elements tend to be short one or two electron or have one or two extra electrons.

Which aqueous solution has the lowest boiling point? A.0.20 m (NH4)2S
B. 0.20 m FeI3
C. 0.20 m K2SO4
D. 0.20 m C2H5OH

Answers

Answer:- D. 0.20 m $C_2H_5OH$

Explanations:- When a on volatile solute is added to a solvent then the boiling point of the solution increases(elevated) and we call it elevation in boiling point.

Elevation in boiling point is directly proportional to the molality of the solution and the Van't Hoff factor "i" which is the number of ions we get on dissociation.

The equation is written as:

$\Delta T_b=imk_b$

where $k_b$ is the boiling point elevation constant.

We have all the aqueous solutions, so the boiling point elevation constant value will remain same for all of them. The molality for all the solutions is also same. So, elevation in boiling point will depend only on the value of Van't Hoff factor.

Lower is the value of "i", lower will be the boiling point and vice versa.

The question asks, which aqueous solution has the lowest boiling point. So, we nede to choose the one with the lowest value of "i".

$(NH_4)_2S(aq)\rightarrow 2NH_4^+(aq)+S^2^-(aq)$

i = 3

$FeCl_3(aq)\rightarrow Fe^3^+(aq)+3I^-(aq)$

i = 4

$K_2SO_4(aq)\rightarrow 2K^+(aq)+SO_4^2^-(aq)$

i = 3

$C_2H_5OH$ is a covalent molecule and so it does not dissociate to give the ions and hence the value of "i" for this is 1.

Comparing the "i" values for all the solutions, the least value is for ethyl alcohol means the boiling point of 0.20 m ethyl alcohol solution will be lowest.

So, the correct answer is D. 0.20 m $C_2H_5OH$ .
