Answer 2

Matching Equations with Reaction Types:

1) 2K + 2H2O → 2KOH + H2 - This equation represents a combination reaction, also known as a synthesis reaction. In a combination reaction, two or more substances combine to form a single product.

2) Al(OH)3 + HNO3 → Al(NO3)3 + 3H2O - This equation represents a double displacement reaction, also known as a metathesis reaction or a precipitation reaction. In a double displacement reaction, the positive and negative ions of two compounds switch places to form two new compounds.

3) BaO + N2O5 → Ba(NO3)2 - This equation represents a combination reaction. As mentioned earlier, a combination reaction involves the combination of two or more substances to form a single product.

4) 2KClO3 → 2KCl + 3O2 - This equation represents a decomposition reaction. In a decomposition reaction, a single compound breaks down into two or more simpler substances.
