34 atoms of carbon (C) react with 22 molecules of hydrogen gas (H2). How many molecules of methane (CH4) will be formed, and what will be left over? A. 17 molecules of methane formed, 5 molecules of hydrogen left over
B. 11 molecules of methane formed, 23 molecules of carbon left over
C. 5 molecules of methane formed, 24 atoms of carbon and 2 molecules of hydrogen left over
D. 22 molecules of methane formed, 12 atoms of carbon left over

so what is the problem with your lab report and whats the subject of the lab report? i will you

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.
