4. Calculate the mass of each element: a) 3.25 mol of He
b) 0.0455 mol of Ni
c) 1.33 mol of K

Matches the chemical name of each oxide of phosphorus to its chemical formula

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 -

Solutions of sodium carbonate and silver nitrate react to form solid silver carbonate and a solution of sodium nitrate. a solution containing 3.50 g of sodium carbonate is mixed with one containing 5.00 g of silver nitrate. how many grams of sodium carbonate, silver nitrate, silver carbonate, and sodium nitrate are present after the reaction is complete?
