a. move across the membrane to the outside of the cell.
b. stop moving across the membrane.

What type of reaction is illustrated? 2c12o5 = 2cl2 + 502

Which of these features are formed when hot groundwater is forced out through cracks in the earth's surface?

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.
