It’s D because the other ones don’t aren’t true
Answer:
A
Explanation:
There are three states of mater; solid liquid and gas. The sold state is the difficult to compress while the gaseous state is quite easy to compress.
A gas is easily compressed because the particles in a gas are far apart from each other. A solid is difficult to compress because the particles of a solid are close together. From all the above statements, it is easily deducible that the compressibility property of a substance in a particular state of matter depends on the proximity of the particles to each other, hence the answer above.
Reduction
half reaction
2H_2O
+ CrO_4^2- + 3e -> CrO_2^- + 4OH^-
Oxidation
half reaction
2OH^-
+ SO_3^2- -> SO_4^2- + H_2O + 2e
Balanced
overall equation
H_2O
+ 2CrO_4^2- + 3SO_3^2- -> 3SO_3^2- + 2CrO_2^- + 2OH^-

You need to make sure all reactants and products are balanced on both sides of the equation.
