2. Write word equations for these reactions: (a) Sugar breaks down into carbon and water,
(b) Iron, water, and oxygen produce rust.
(c) Carbonic acid breaks down

Explanation:

glucose -> carbon + water

iron + water + oxygen -> iron oxide

carbonic acid -> carbon dioxide + water

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

beta decay is the answer
