5) How many Kilograms are in 12 L of Chlorine Gas?

0.03798 kilograms

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

To calculate the moles, we use the equation:

1 mole of chlorine gas weighs = 71 g

Thus 0.535 moles of chlorine gas will weigh =            (1kg=1000g)

Thus there are 0.03798 kilograms in 12 L of chlorine gas.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
