Factories that produce cement account for around 5% of global emissions of carbon dioxide worldwide. Carbon dioxide is a greenhouse gas that absorbs solar radiation and rereleases it into Earth's atmosphere.
Cement production has increased over time because the demand for cement has increased. Suppose that cement production continues to increase significantly over the next 50 years. Assuming that all other factors remain the same, what impact will this most likely have on the Earth?
A Gas other than carbon dioxide will become more concentrated in the atmosphere.
B Global temperatures on Earth will increase.
C Global temperatures on Earth will decrease.
D Gases other than carbon dioxide will become depleted in the atmosphere.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
