Type the correct answer in the box. express the answer to three significant figures.
given:
ch4 + 2o2 → co2 + 2h2o, δh = -890 kj/mol
how much energy is released when 59.7 grams of methane (ch4) reacts with oxygen?
the combustion of 59.7 grams of methane releases
kilojoules of energy.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
