When 2.50 g of methane burns in oxygen, 125 kJ of heat is produced. The molar mass of CH4 is 16.04 g/mol. What is the enthalpy of combustion per mole of methane under these conditions?

the answer is minerals.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
