Describe how elements joining together to form chemical compounds is similar to the way the letters on a computer keyboard join together to form words. Please help me with this question I need it for Science on Tuesday!

Answer 1

1.25 x 10^23 scholars x (1 mol / 6.02 x 10^23 pupils) = 0.208 mol pupils 1 mol = 6.02 x 10^23 1.44 mol Mg x (6.02 x 10^23 atoms / 1 mol) = eight.67 x 10^23 atoms Mg 99.2 mol H2O x (6.02 x 10^23 molecules / 1 mol) = 5.97 x 10^25 molecules H2O 3.44 x 10^24 molecules O2 x (1 mol / 6.02 x 10^23 molecules) = 5.Seventy one mol O2 1 mol of every of the following comes in atoms: Mg, Cu, Fe, He, Ne, etc.(monatomic factors) 1 mol of every of the following comes in molecules: H2O, SO2, CO2, Cl2, and so forth. (covalent supplies) 1 mol of every of the next is available in components units: NaCl, BaCl2, CaCO3 (ionic components)
