A 10.0 gram sample of a compound that had a molar mass of 156 g/mol is placed into a perfect calorimeter containing 100.0 mL of water. It decomposes in aqueous solution and the temperature rises from 25C to 35C. For this compound, what is the enthrall of decomposition?

The compound methyl butanoate smells like apples. its percent composition is 58.8% c, 9.9% h, and 31.4% o. what’s the empirical formula ?

What is the mass of 8 moles of sodium atoms

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
