sure :). Problem?

anonymous · Answer

What volume (in ml) of 1.50 M hydrochloric acid is required to completely react 4.30 g of nickel metal producing nickel (II) chloride (assuming 100% yield)?

What mass of nickel (II) chloride would be predicted to be produced (after all the water is evaporated)?

What mass of hydrogen gas and how many atoms of hydrogen were released by the reaction?

ok, so first you need to set up a balanced equation.

From reading the question, you know that the reactants will be hydrochloric acid and nickle metal, and product will be nickle (II) chloride and hydrogen gas. Now balance it :)
