How many moles of copper (Cu) are in one mole of CuCl2 ? HELP ASAP

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -

What is the molarity of 60.0 grams of naoh dissolved in 750 milliliters of water? a) 1.1 m b) 2.0 m c) 12 m d) 75 m

How will the volume of a gas be affected if the pressure is tripled, but the temperature remains the same?
