Ions are Formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells.
Answer: 75%
Explanation:
The following information can be gotten from the question:
Waste = 70kg
Theoretical yield = 280kg
Therefore, the actual yield will be the difference between the theoretical yield and the waste which will be:
= 280kg - 70kg = 210kg
The percent yield will now be:
= Actual yield / Theoretical yield × 100
= 210/280 × 100
= 3/4 × 100
= 75%
Answer:
combination reaction
Explanation:
i'm not sure i just searched it on the internet
Molality= moles of solute /kg of solvent
moles of solute= mass/molar mass
moles of solute= 3.94 g / (342 g/mol)
moles of solute= 0.01 mol
molality= 0.01 mol / 0.285 kg
molality= 0.04 m
