What is the molarity of a solution that contains 2 moles of KCl in 4 L of solution? a 2.0 M b 0.5 M c 0.25 M d 8.0 M

Which list of elements contains two metalloids? (1) Si, Ge, Po, Pb (3) Si, P, S, Cl (2) As, Bi, Br, Kr (4) Po, Sb, I, Xe

he compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 3.376 g sample of BHT was combusted in an oxygen rich environment to produce 10.11 g of CO2 (g) and 3.312 g of H2O (g).

You already saw that 1.00 g of Al should yield 3.53 g of copper for the reaction below. 3CuCl2 (aq) + 2Al (s) ⟶ 2AlCl3 (aq) + 3Cu (s) However, impurities and errors can occur easily. Suppose that only 2.86 g of copper is produced.
