Question

how can the ratio of different elements affect matter?
a it affects the temperature of matter.
b it has no impact on matter.
c it affects the physical and chemical properties of matter.
d it determines the size of matter.

Explanation:

The ratio of different elements in a substance determines its chemical - formula and structure. This, in turn, affects its physical and chemical properties such as melting point, reactivity, etc. Temperature is related to thermal energy, not directly to element ratios. Element ratios definitely have an impact on matter, and they do not determine the size of matter.

Answer:

C. It affects the physical and chemical properties of matter.
