Put the following steps in sequence to describe how chemical sedimentary rocks form ?
1. when a body of water becomes saturated with dissolved minerals, crystal precipitate out of solution
2) they settle to the bottom , creating layers of sedimentary rock
3) during chemical weathering , minerals can be dissolved and carried into lakes and ocean

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.
