Balance the follow equations
_N2+_H2 ->_NH3

N2 + 3H2 —> 2NH3

The coefficients are 1, 3, 2

Explanation:

N2 + H2 —> NH3

The equation can be balance by doing the following:

There are 2atoms of N on the left side and 1atom on the right. It can be balance by putting 2 in front of NH3 as illustrated below:

N2 + H2 —> 2NH3

Now, there are 6 atoms of H on the right side and 2 atoms on the left. It can be balance by putting 3 in front of H2 as shown below

N2 + 3H2 —> 2NH3

Now the equation is balanced.

The coefficients are 1, 3, 2

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
