When a candle burns it produced 41,300 Joules per 1 gram. Use dimensional analysis to convert this to Calories per pound. 1 cal = 4.184 J

16 ounces = 1 pound

1 ounce = 23.5 grams

1 Calorie= 1000 calories

4477381.7 calories/pound

Explanation:

It is given that,

When a candle burns it produced 41,300 Joules per 1 gram.

We need to convert it into calories per pound.

We know that,

1 cal = 4.184 J

⇒ 1 J = (1/4.184) cal

1 pound = 453.592 grams

⇒1 g = (1/453.592) pounds

Now,

Hence, 41,300 Joules/gram = 4477381.7 calories/pound.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
