Question

Решить формулы: Fe+O2=; Ag+F2=; S(2)+H2=; Cu+S(2)=; S(4)+Cl2(7)=

Answer 1

3Fe + 2O2 =Fe3O4
Ag + F2 =AgF2
S +H2= =H2S
Cu+S =CuS
S+Cl2= SCl2

Answer 2

3Fe+2O2= 2Fe3O4 - оксид железа;
Ag+F2 = AgF2 - фторид серебра (соль);
S(2)+H2= H2S - сероводород (кислота);
2Cu+S(2)= Cu2S - сульфид меди (соль);
S(4) + 2Cl2 = SCl4 - тетрахлорид серы (соль)

Answer 3

To solve these chemical equations, we need to balance them by making sure that the number of atoms of each element is the same on both sides of the equation. I'll balance each equation step by step:

1. Fe + O2 = Fe2O3
2. Ag + F2 = AgF
3. S + H2 = H2S
4. Cu + S = CuS
5. S4 + Cl2 = SCl4

Explanation:

1. Fe + O2 = Fe2O3 To balance this equation, we need to have two iron (Fe) atoms on the left side to match the two iron atoms on the right side. We also need three oxygen (O) atoms on the left side to match the three oxygen atoms on the right side.

Balanced equation: 4 Fe + 3 O2 = 2 Fe2O3

2. Ag + F2 = AgF This equation is already balanced. There is one silver (Ag) atom on both sides, and two fluorine (F) atoms on both sides.

Balanced equation: Ag + F2 = AgF

3. S + H2 = H2S To balance this equation, we need two hydrogen (H) atoms on the left side to match the two hydrogen atoms on the right side.

Balanced equation: S + H2 = H2S

4. Cu + S = CuS This equation is already balanced. There is one copper (Cu) atom on both sides, and one sulfur (S) atom on both sides.

Balanced equation: Cu + S = CuS

5. S4 + Cl2 = SCl4 To balance this equation, we need four chlorine (Cl) atoms on the right side to match the four sulfur (S) atoms on the left side.

Balanced equation: S4 + 2 Cl2 = SCl4

Note: Please keep in mind that S(2) and S(4) are not standard chemical notations. If you meant S2 and S4, then the above-balanced equations are correct. If there's a specific notation you were referring to, please clarify, and I'll do my best to address it.
