The most abundant dissolved salt in ocean water is
a. sodium saline.
c. sodium chloride.
b. sodium fluoride.
d. sodium chlorine.

Sodium chloride is the most most abundant dissolved salt in ocean water.

Explanation:

Oceans are made of sea water and sodium chloride is the most abundant dissolved salt in ocean water.

Sea water upon evaporation leaves a salt. This salt is then collected and purified for human use. As sea water gets contaminated due to the dirty water coming from various sources.

Therefore, the sodium chloride in sea water also gets contaminated. Hence, purification of this salt is required.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

it means there are 3 atoms of oxygen
