Classify each of these reactions. Ba(ClO3)2 → BaCl2 3 O2 double replacement combination single replacement decomposition CaO CO2
faltersainse [42]

Answer:

Ba(ClO₃)₂ → BaCl₂ +  3 O₂ <em>Descomposition. </em>

CaO + CO₂ → CaCO₃ <em>Combination. </em>

NaNO₂ +  HCl → NaCl + HNO₂ <em>Double replacement. </em>

Mg + ZnSO₄ → MgSO₄ + Zn <em>Single replacement. </em>

Explanation:

A combination reaction is defined as a reaction in which two or more substances combine to form a single new substance.

A + B → AB

A descomposition reaction is defined as a reaction in which a compound breaks down into two or more simpler substances.

AB → A + B

A double replacement is a chemical reaction were the positive and negative ions of two ionic compounds exchange places to form two new compounds.

AB + CD → AD + CB

A single replacement is another type of reaction were one element replaces a similar element in a compound.

A + BC → AC + B

Thus, with this information it is possible to classify these reactions as:

Ba(ClO₃)₂ → BaCl₂ +  3 O₂ <em>Descomposition. </em>One single molecule breaks down into two or more molecules

CaO + CO₂ → CaCO₃ <em>Combination. </em>Two substances are combined to form one single molecule

NaNO₂ +  HCl → NaCl + HNO₂ <em>Double replacement. </em>Na and H are exchange places to form two new compounds

Mg + ZnSO₄ → MgSO₄ + Zn <em>Single replacement. </em>Mg is replacing Zn.

I hope it helps!
