Match the reaction on the right with the corresponding reaction on the left by writing the correct, matching number in the space provided. solid sodium + chlorine gas → solid sodium chloride solid sodium + liquid water → aqueous sodium hydroxide + hydrogen gas 2h2(g) + o2(g) → 2h2o(g) 2h2o2(aq) → o2(g) + 2h2o(l) 1) aqueous hydrogen peroxide → oxygen gas + liquid water 2) 2na(s) + cl2(g) → 2nacl(s) 3) hydrogen gas + oxygen gas → water gas 4) 2na(s) + 2h2o(l) → 2naoh(aq) + h2(g)

Explanation:

The first given equation in words is as follows.

solid sodium + chlorine gas solid sodium chloride

The chemical equation for this reaction will be written as follows.

The second given equation in words is as follows.

solid sodium + liquid water aqueous sodium hydroxide + hydrogen gas

The chemical equation for this reaction will be written as follows.

The third given equation is as follows.

This equation can be written in words as follows.

hydrogen gas + oxygen gas water gas

The fourth given equation is as follows.

This equation can be written in words as follows.

aqueous hydrogen peroxide oxygen gas + liquid water

Thus, match the given data as follows.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

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.
