Consider the following unbalanced particulate representation of a chemical equation: H = light blue
I = purple
Write a balanced chemical equation for this reaction, using the smallest integer coefficients possible. Do not include states.

H₂ + I₂ —> 2HI

Explanation:

From the question given above, we were told that:

H => Light ball

I => Purple ball

We can obtain the balanced equation for the reaction as follow:

H₂ + I₂ —> HI

There are 2 atoms of H on the left side and 1 atom on the right side. It can be balance by writing 2 before HI as shown below:

H₂ + I₂ —> 2HI

Now, the equation is balanced.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
