To determine how many grams of ethylene (C₂H₄) must burn to release 70.0 kg of heat, we first need the heat of combustion of C₂H₄, which is approximately 1410 kJ/mol. Converting 70.0 kg of heat to kJ gives 70,000 kJ. Using the heat of combustion, we can calculate the moles of C₂H₄ needed: 70,000 kJ ÷ 1410 kJ/mol ≈ 49.6 mol. Finally, multiplying by the molar mass of C₂H₄ (about 28.05 g/mol) gives approximately 1390 grams of C₂H₄ required.

How many grams in 1 cm cube?
It is a very good question. I am pretty sure it is about 10 grams. This is possible because one millimeter is the same as one gram. Hence I figured that since one centimeter in ten millimeters I thought that you should times it by ten. So the answer should be ten.

A person would have to burn about four calories to equate one gram of protein. Carbohydrates also contain four calories per gram, while fat contains nine.
Why would a burn produced by 1 gram of steam do more damage than a burn caused by 1 gram of water?
Greater latent heat in steam due to phase change.
How long to burn 1 gram of trans fat?
A gram of any kind of fat is about 8 calories. The time to burn it depends on your activity. You burn calories even at rest (1.6 calories/hour) so at rest it would take you about 5 hours to burn 1 gram of fat. If instead of sitting alone in a chair you were kissing someone you would burn 8 calories in about 5 minutes. If you were walking you would burn 8 calories in 2 or 3 minutes.

How many molecules of in 1.26 x 10 3 grams of c2h4?
The gram molecular mass of C2H4 is 28.05. Therefore, 1.26 X 103 grams constitutes (1.26/28.05) X 103 or about 44.9 moles. Each mole contains Avogadro's number of molecules; therefore, 1.26 X 103 grams contains 2.71 X 1025 molecules, to the justified number of significant digits.
