Answer 1

Объяснение:

2K + Br2 → 2KBr

2CH4 → C2H2 + 3H2

3Mg + N2 → Mg3N2

2Ag2O → 4Ag + O2

H2 + F2 → 2HF

Cr2O3 + 2Al → Al2O3 + 2Cr

2CuO + 2C → 2Cu + CO2

MgCl2 + 2KOH →2 KCl + Mg(OH)2

3CaBr2 + 2K3PO4→6 KBr + Ca3(PO4)2

Answer 2

The reactions you provided are balanced chemical equations. Here is the balanced equation for each reaction:

1. K + Br2 → 2KBr
2. CH4 → C2H2 + 2H2
3. 3Mg + N2 → Mg3N2
4. 2Ag2O → 4Ag + O2
5. H2 + F2 → 2HF
6. 2Cr2O3 + 4Al → 4Al2O3 + 6Cr
7. CuO + C → Cu + CO2
8. MgCl2 + 2KOH → 2KCl + Mg(OH)2
9. 3CaBr2 + 2K3PO4 → 6KBr + Ca3(PO4)2

These equations represent the balanced chemical reactions where the reactants on the left side of the arrow undergo a chemical change and produce the products on the right side of the arrow. The coefficients in front of each compound indicate the relative number of molecules or moles involved in the reaction, ensuring that the law of conservation of mass is satisfied.
