how many grams of benzoic acid are necessary to react with 20.00 mL of the NaOH solution? The molar mass of benzoi cb acid is 122.12 g/mol. PLZ HELP!!!

The drawing represents the movement of particles in a substance. what changes of state can this substance undergo

For ai it's atomic number is 13 and it's mass number is 27 how many neutrons does it have

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
