The volume of o2 at NTP required for combustion of 1 mole of methane is​

Thus for 1 mole methane we need 2 mole of oxygen for complete combustion. Hence 0.5 moles of oxygen will occupy 22.4 L x 0.5 = 11.2 L. hope it helps you.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

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.
