Acompound has a chemical composition of 72 g carbon, 12 g hydrogen, 16 g oxygen. what is the empirical formula? answer asap choices are : a. c6h12o b. c1.5h6o c. cho d. no answer text provided. e. c6h12o2

The empirical formula is the formula given, but only counts one of each.

The question given gives us a composition of 72g Carbon, 12g Hydrogen, & 16g oxygen.

Carbon = C, Hydrogen = H, Oxygen = O

Remember that the empirical formula only gives one of each, and the three elements inside the question given is Carbon, Hydrogen, and Oxygen. This means that your answer is:

C. CHO: 1 Carbon, 1 Hydrogen, 1 Oxygen.

(C) is your answer

hope this helps

u i forgot the answer?

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.
