Write a balanced Chem. Eq

1. Chlorine gas will react with aqueous sodium fluoride if 200J of energy is added and manganese is used as a catalyst.

2. Dinitrogen pentaoxide gas decomposes into its elemental parts.

Cl2 (g) + NaF (aq)>> NaCl(aq) + F2 (g)

and write heat, Mg above the >>

2N2O5>>2N2 + 5O2

1. The balanced chemical equation for the reaction between chlorine gas and aqueous sodium fluoride with the use of manganese as a catalyst, when 200J of energy is added, is as follows:

Cl2(g) + 2NaF(aq) + Mn(s) + 200J → 2NaCl(aq) + MnF2(s)

In this equation, chlorine gas (Cl2) reacts with aqueous sodium fluoride (NaF) in the presence of manganese (Mn) as a catalyst. The addition of 200J of energy is represented on the reactant side of the equation. The products of the reaction are sodium chloride (NaCl) in aqueous form and manganese fluoride (MnF2) as a solid.

2. The balanced chemical equation for the decomposition of dinitrogen pentoxide gas into its elemental parts is as follows:

2N2O5(g) → 4NO2(g) + O2(g)

In this equation, dinitrogen pentoxide (N2O5) gas decomposes to form four molecules of nitrogen dioxide (NO2) gas and one molecule of oxygen (O2) gas.

To write a balanced chemical equation, we need to determine the reactants and products involved in the given chemical reactions and then balance the equation by ensuring that the number of atoms of each element is equal on both sides.

1. The given reaction is:
Chlorine gas (Cl₂) + Aqueous sodium fluoride (NaF) → ?

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. Here's how we can do it:

First, let's identify the elements present on each side of the equation:
Reactants: Chlorine (Cl) and Sodium (Na)
Product: Sodium (Na) and Fluorine (F)

The balanced chemical equation for this reaction is:
Cl₂ + 2NaF → 2NaCl + F₂

2. The given reaction is:
Dinitrogen pentoxide (N₂O₅) → ?

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. Here's how we can do it:

First, let's identify the elements present on each side of the equation:
Reactant: Nitrogen (N) and Oxygen (O)
Products: Nitrogen (N) and Oxygen (O)

The balanced chemical equation for this reaction is:
2N₂O₅ → 4NO₂ + O₂

Note: It's important to note that while balancing the equation, we only change the coefficients (the numbers in front of the chemical formulas) and not the subscripts within the chemical formulas.
