What is the theoretical yield of CC14 for a reaction using 80 g C12? If the actual yield from the reaction is 38 g of CCI4, what is the percent yield of CC14? Step 1 gram to gram Step 2 PY= (Actual/Theoretical) x 100. Molar Mass of Ch2= 70 g/mol, Molar mass of CC14= 152 g/mol C + 2C12--> CC14

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
