How many liters of chlorine gas, at standard temperature and pressure, will react with 15.5 grams of potassium metal? show all of the work used to solve this problem. 2k + cl2 yields 2kcl

Explain which group an element with the electron configuration 1s2 2s2 2p6 3s2 3p6 3d1 4s2 belongs to.

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.
