The image contains two questions. The first, a chemistry question, is incomplete as the chemical reaction is not provided. The second is a mathematics question.
For the mathematics question:
The dimensions of the rectangular floor are $12 \text{ m}$ by $20 \text{ m}$.
To cover the floor with square tiles of maximum size, the side length of the tile must be the greatest common divisor (GCD) of the floor's dimensions.
Step 1: Find the prime factorization of each dimension.
$$12 = 2 \times 2 \times 3 = 2^2 \times 3$$
$$20 = 2 \times 2 \times 5 = 2^2 \times 5$$
Step 2: Determine the greatest common divisor (GCD).
The common prime factors are $2^2$.
$$\text{GCD}(12, 20) = 2^2 = 4$$
The side length of the maximum size square tile is $4 \text{ m}$.
The question is cut off, but assuming it asks for the side length of the maximum size tile:
The side length of the maximum size square tile is $\boxed{\text{4 m}}$.
Regarding the chemistry question "(b) write a net ionic equation for the chemical reaction", the chemical reaction itself is not provided in the image, so a net ionic equation cannot be written.
