F₂ + 2NaBr→ 2NaF +Br₂

The chemical equation above show the conservation of matter because

The number of F atoms in the reactants equal the number of F atoms in the product (answer C)

Explanation

According to the law of mass of matter conservation, the number of atoms in the reactants side should be equal to number of atoms in products side.

For example in reaction above the number of F atoms in reactants side equal the number of F atoms in the products side.Therefore the equation above show the conservation of matter.

Answer :

$MgSO_4$ solution contains $Mg^{2+}$ and $SO_4^{2-}$

$NaNO_3$ solution contains $Na^{+}$ and $NO_3^{-}$

Explanation :

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

All the polyatomic ions always form an ionic compound.

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

The given compounds are, $MgSO_4$ and $NaNO_3$

$MgSO_4$ is an ionic compound which is formed by the combination of $Mg^{2+}$ cation and $SO_4^{2-}$ anion.

and,

$NaNO_3$ is an ionic compound which is formed by the combination of $Na^{+}$ cation and $NO_3^{-}$ anion.

<h2>9. Given : P + O2 = P2O5</h2>

Balanced Chemical Equation: 4P + 5O2 = 2P2O5

Reactant Product

P = (1) 4 | P = (2) 4

O = (2) 10 | O = (5) 10

Reaction Information

Phosphorus + Dioxygen = Phosphorus Pentoxide

Reaction Type: Synthesis

<h2>10. Given: HCl + NaOH = NaCl + H2O </h2>

Reactant Product

H = 2 | H = 2

Cl = 1 | Cl = 1

Na = 1 | Na = 1

O = 1 | O = 1

<h3>Chemical Equation is already in balance.</h3>

Reaction Information: Hydrogen Chloride + Sodium Hydroxide = Sodium Chloride + Water

Reaction Type : Double Displacement (Acid-Base)
