This question involves a reaction between copper oxide, CuO, and sulfuric acid, H2SO4: CuO+H₂SO₄→CuSO₄+H₂O
What mass of water is produced when 2.0 g of copper oxide reacts with an excess of sulfuric acid?
(Relative formula masses are: CuO = 79.5; H2O = 18)
Give your answer to 2 decimal places.

What is the solubility of substance?

Which statement correctly describes metallic bonds? a. they form when certain atoms lose electrons and other atoms gain electrons. b. they involve an attraction between anions and cations. they always involvpoth a metal and a nonmetal. d. they can only form between atoms of the same element. e. they form because electrons can move freely between atoms.

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?
