What kind of solution would you have if it contained 50 grams of sodium coride in 100 ml of water at 39 c

Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

If the atomic mass of an atom is 34 and the atom contains 13 protons, how many neutrons does the atom contain?

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate, m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2
