Answer:
0.185moles
Explanation:
1mole of bicarbonate produces 1mole of CO2
so 0.185 mole produces 0.185 moles of CO2
In order to calculate the yield, we first need the theoretical and actual yields since the formula is:
Percentage yield = (actual yield / theoretical yield) x 100
The theoretical yield is calculated using the reaction equation which is:
2NaNO₃ + CuCl₂ → 2NaCl + Cu(NO₃)₂
The moles of copper chloride reacting are: 31 / 134 = 0.23
So the moles of sodium chloride produced should be: 2 x 0.23 = 0.46
The mass of sodium chloride (theoretical yield) should be: 0.46 x 58 = 26.68 g
Percentage yield = (21.2 / 26.68) x 100
Percentage yield = 79.5%

Answer:
Explanation:
Ionic compound are compounds formed by one atom losing an electron while the other gains electron as such the solution always contain charge ions compared to covalent solution which is predominantly formed by two atoms sharing electron. The two solution should be connected to a circuit with a bulb in turns with the same circuit, the solution that turns the bulb on is the ionic solution. This is because their charged ions conducts electricity when voltage is passed through it while the covalent solution does not conduct electricity.
