CuSO4(aq) + Zn(s) — Cu(s) + ZnSO4(aq) The single-replacement reaction above produces 102.0 g of copper and an unknown
concentration of zinc sulfate. With excess CuSO4, what mass of Zn was used?
Molar mass of Cu: 63.55 g/mol
Molar mass of Zn: 65.38 g/mol

g of zinc (Use 4 sig figs)

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

Chromosome 17 is made of over million base pairs.
