Question

Mgo+co2= CuSo4+Koh= Al+H2So4=

Answer 1

$MgO + CO_2 \rightarrow MgCO_3 \\ CuSO_4 + 2KOH \rightarrow K_2SO_4 + Cu(OH)_2 \\ 2Al + 3H_2SO_4 \rightarrow Al_2(SO_4)_3 + 3H_2$

Answer 2

It looks like you've provided three chemical reactions. However, the first and second reactions are incomplete, and the third reaction is missing the products. Let's try to complete and balance the reactions:

1. Incomplete reaction: Mgo + CO2 = CuSo4 + KOH

To balance this reaction, we need the correct reactants and products. Assuming you meant magnesium oxide (MgO) as the reactant, the balanced equation would be:

MgO + CO2 → MgCO3

2. Incomplete reaction: CuSo4 + KOH = ?

Similar to the previous reaction, we need the correct products for this equation. Assuming you meant copper(II) sulfate (CuSO4) and potassium hydroxide (KOH) as the reactants, the balanced equation would be:

CuSO4 + 2KOH → Cu(OH)2 + K2SO4

3. Reaction: Al + H2SO4 = ?

In this reaction, aluminum (Al) reacts with sulfuric acid (H2SO4). The balanced equation would be:

2Al + 3H2SO4 → Al2(SO4)3 + 3H2

Now, all three reactions are balanced with their correct reactants and products.
