Question

Al + H SO = Ca + HCl =Ag + HCl =Fe,, + HCl =HgO + H.SO, =CaO + H PO =Fe(OH), + H,SO, =CuO + H,SO=​

Answer 1

Ответ:

1) 2Al + 3H2SO4 = Al2(SO4)3 + 3H2

2) Ca + 2HCl → CaCl2 + H2

3) 2 Ag + 2 HCl ← H2 + 2 AgCl (эта реакция в нормальных условиях не происходит, потому что H2 является более реакционноспособным чем Ag)

4) Fe + 2 HCl → FeCl2 + H2

5) HgO + H2SO4 → HgSO4 + H2O

6) 2 HPO3 + 3 CaO = Ca3(PO4)2 + H2O

Answer 2

It seems like you've written some chemical equations, but some of them are incomplete or incorrect. I'll try to correct and balance them for you:

1. Balanced equation for the reaction between aluminum (Al) and sulfuric acid (H2SO4): 2 Al + 3 H2SO4 → Al2(SO4)3 + 3 H2

2. Balanced equation for the reaction between calcium (Ca) and hydrochloric acid (HCl): Ca + 2 HCl → CaCl2 + H2

3. Balanced equation for the reaction between silver (Ag) and hydrochloric acid (HCl): Ag + HCl → AgCl + H2

4. Balanced equation for the reaction between iron (Fe) and hydrochloric acid (HCl): Fe + 2 HCl → FeCl2 + H2

5. Balanced equation for the reaction between mercury oxide (HgO) and sulfuric acid (H2SO4): HgO + H2SO4 → HgSO4 + H2O

6. Balanced equation for the reaction between calcium oxide (CaO) and phosphoric acid (H3PO4): CaO + 3 H3PO4 → Ca(H2PO4)2 + H2O

7. Balanced equation for the reaction between iron(III) hydroxide (Fe(OH)3) and sulfuric acid (H2SO4): Fe(OH)3 + 3 H2SO4 → Fe2(SO4)3 + 3 H2O

8. Balanced equation for the reaction between copper oxide (CuO) and sulfuric acid (H2SO4): CuO + H2SO4 → CuSO4 + H2O

Please note that some of the reactions you provided might not be feasible or realistic under standard conditions, and they could involve more complex chemical species or require specific reaction conditions to occur.
