Answer: 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.
Answer:
a what is the HCO3"/CO2 ratio
A) mixture because they are not chemically combined
Answer:
Explanation:
When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released and photon is emitted.
this emitted photon is depicted as a small wave-packet being expelled by the atom in a well-defined direction.
