Question

K8 + CI2 > KCl6

K + B2O3 > K2O + B



balance the equation and show me the new equation

Answer 1

To balance the given chemical equations, we will ensure that the number of atoms of each element is the same on both sides of the reaction.

1. **For the first equation:**
\[
K_8 + Cl_2 \rightarrow KCl_6
\]

The balanced equation can be derived as follows:

- On the reactant side, we have 8 potassium (K) atoms.
- On the product side, KCl is producing 6 Cl atoms for every K, so we need to balance Cl2 to provide the correct number of chlorine atoms.

The balanced equation is:
\[
K_8 + 6Cl_2 \rightarrow 4KCl_6
\]
Here, we have 8 K atoms and 12 Cl atoms on both sides.

2. **For the second equation:**
\[
K + B_2O_3 \rightarrow K_2O + B
\]

To balance this reaction:

- We recognize that 1 formula unit of B2O3 contains 2 B, so we’ll need 2 K2O molecules to balance the potassium (K) atoms.
- Therefore, we will need 6 K from 2 K2O, and this will produce 2 B.

The balanced equation is:
\[
6K + B_2O_3 \rightarrow 3K_2O + 2B
\]

Now both equations are balanced:

1. \( K_8 + 6Cl_2 \rightarrow 4KCl_6 \)
2. \( 6K + B_2O_3 \rightarrow 3K_2O + 2B \)
