OILRIG:
Oxidation is loss (of electrons)
Reduction is gain (of electrons)
so...
The first one is an oxidation half-equation as the Sn loses electrons;
The second one is a reduction half-equation as the Cl₂ gains electrons

Explanation:
distillation, process involving the conversion of a liquid into vapour that is subsequently condensed back to liquid form. ... This basic operation requires the use of a still or retort in which a liquid is heated, a condenser to cool the vapour, and a receiver to collect the distillate.

Answer:
Cooling lowers the rate of the chemical reaction in the batteries.
Explanation:
When a battery is not in use and it may undergo some chemical changes which leads to decrease in its life (shelf life).
For example in case of Zinc battery, the zinc undergoes reaction with ammonia which deteriorate the cell or battery.
Now if we keep the battery in a cool place like refrigerator, the rate of chemical reaction will decrease (the rate of reaction generally decreases with decrease in temperature). Thus the battery stay fresh longer.
Answer:
56.97kJ
Explanation:
1 mole of N2 reacts with 73.8kJ
0.772 mole of N2 reacts with xkJ
cross multiply
x= 0.772×73.8
=56.97kJ
