Which half-reaction goes first in a REDOX process?

Don't think it matters.

Explanation:

In terms of classifying them, find the oxidation numbers first. Reduction half-reaction will gain electrons, so oxidation number will decrease across. Oxidation half-reaction will lose electrons, so oxidation number will increase across.

the answer is a. co2, this would be colder than the : )

explanation:

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
