A
Explanation:
Waxing means getting bigger.
Waning is.. you guessed it... the exact opposite.
The density of liquid water is 1 kg/L.
Mass of water = (1 kg/L)(2.5 L)(1000 g/1 kg) = 2500 g water
The molar mass of water is 18 g/mol.
Moles of water = 2500 g / 18 g/mol = 138.889 mol water
According to Avogadro's number, in one mole of any substance, there are 6.022×10²³ atoms.
Atoms of water = 138.889 mol * 6.022×10²³ atoms/mol = 8.364×10²⁵ atoms of water
In every atom of water, there are 10 protons: 8 from one oxygen atom, and 1 each from the two hydrogen atoms.
Protons of water = 8.364×10²⁵ atoms * 10 protons/atom
<em>Protons of water = 8.364×10²⁶ </em>

Answer: The reaction between bromine gas and fluorine gas to create bromine monofluoride gas has reached equilibrium. What is the effect of adding more bromine gas to the reaction chamber?
More fluorine gas will be produced.
More bromine gas will be produced.
More bromine monofluoride gas will be produced.
Less bromine monofluoride gas will be produced.
I think it is more bromine monofluoride will be produce
