Suppose that new evidence from many new experiments does not support an existing scientific theory. Which of the following is most likely to happen? A. The theory will be revised.
B. The new evidence will be changed to support the theory.
C. New experiments will be conducted until evidence supporting the theory is obtained.
D. The theory will not be affected in any way.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

option c: 1605.1 kj

the balanced chemical reaction for combustion of methane is as follows:

here, enthalpy formation of is -74.7 kj/mol, 0 kj/mol, -393.5 kj/mol and -241.82 kj/mol respectively.

the heat released or can be calculated as follow:

putting the values,

thus, heat released by combustion of 1 mol of methane is 802.54 kj/mol. thus, for 2 mol, heat released will be:

therefore, heat released by the combustion of 2 mol of methane is 1605.1 kj.
