Answer:
A metal atom loses electrons and becomes a positive ion and a non-metal atom gains electrons and becomes a negative ion.
The amount of sodium bromide that would be formed from the reaction will be 7.5524 grams
<h3>Stoichiometric calculation</h3>
Looking at the equation of the reaction:
The mole ratio of CuBr2 and NaCl is 1:2.
Mole of 16.4 grams of CuBr2 = 16.4/223.37
= 0.0734 moles
Mole of 22.7 grams of NaCl = 22.7/58.44
= 0.3884 moles
Equivalent mole of NaCl = 0.1468 moles
Thus, NaCl is in excess while CuBr2 is limiting.
Mole ratio of CuBr2 and NaBr = 1:1
Mass of 0.0734 mole NaBr = 0.0734 x 102.894
= 7.5524 grams

From the Dalton's law of partial pressures, the pressure of the hydrogen gas is 91.83 kPa.
<h3>What is partial pressure?</h3>
In a mixture of gases, the total pressure is the sum of the pressures of the individual gases in the mixture according to the Dalton's law of partial pressures.
In this case, the partial pressure of the hydrogen gas is Phydrogen, the partial pressure of water is Pwater and the total pressure is PT.
Hence;
Phydrogen = PT - Pwater
95 - 3.17 = 91.83 kPa
