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.

Answer:
The number of atoms contained by one molecule of Iron (II) Sulfate are 6.
Explanation:
Iron (II) Sulfate is mage up of two parts. One is the Positive part which constitutes of Fe⁺² and a negative part which constitutes of a polyatomic anion i.e. SO₄²⁻. As there are four Oxygen and one sulfur atom in sulfate Ion so sulfate ion contains 5 atoms in total. Therefore, five atoms from sulfate iona dn one atom of Iron ion makes a total of 6 atoms in one molecule of Iron (II) Sulfate.

Explanation:
Answer:
Equilibrium will lie to the right.
Explanation:

That means HF is stronger acid than
.
Alternatively, it can be said that
is a stronger base than
.
Therefore HF readily gives proton to
to form
and
than the reverse reaction.
So, the equilibrium will lie more towards the right i.e. towards formation of
and
.
