How many liters of C12 gas at 200°C and 0.75
atm can be produced by
the reaction of 12.0 g of
MnO2 (MM= 87 g/mol)
with HCl as follows?
MnO2(s) + 4HCI(aq)
MnCl2(aq) + 2H20(1) +
Cl2(g)​

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

Sally is making a model of a magnesium atom with an atomic mass number of 24 for her chemistry class. she has foam balls for the protons, neutrons, and electrons. she has added 6 neutrons to her model so far. how many more neutrons does she need to add to complete her neutral atom of magnesium?
