7) A gas has a volume of 1000 mL at a temperature of 20 K and a pressure of 760 torr. What will be the new volume when the temperature is changed to 40 K and the pressure
is changed to 380 torr?
I

If i make a solution by adding 83grams of sodium hydroxide to 750ml i’d water what is the molarity of sodium hydroxide

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?

In which reaction is precipitation occurring?
