Which of the following is the balanced chemical equation for the combustion of methane, CH4? A) CH4 (g) + 2O2 (g) → CO2 (g) + 2H20 (g)

B) 2CH4 (g) + O2 (g) → 2CO2 (g) + H20 (g)

C) CH4 (g) + 2O2 (g) → 2CO2 (g) + 2H20 (g)

D) CH4 (g) + 2O2 (g) → CO2 (g) + H20 (g)

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
