In the reaction ______ H2 + N2 ----> 2 NH3, what coefficient should be placed in front of H2 to balance the reaction?
schepotkina [342]

2NH3 is equivalent to N2 + H6 since the 2 at the beginning gets distributed to both atoms. Knowing this you can rewite the equation as

H2 + N2 = H6 + N2

The N2 can cancel out leaving

H2 = H6

You now have to ask ‘2 times what equals 6?’ The answer is obviously 3 at this point.

Bas_tet [7]
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels overtime by not allowing water to INFILTRATE.

Greenhouse gases trap the sun's heat and this is how we can feel it. Without greenhouse gases the earth's average temperature would be 30 degrees less. Other greenhouse gases include water vapor and methane. Increases in the levels of Greenhouse gasses are responsible for present day global warming.

Infiltration is the process by which water enters the soil and eventually becomes part of the groundwater.
