Answer:
B
Explanation:
The average kinetic energy of the particles of gases is directly proportional to the absolute temperature in kelvin and all gases at the same temperature have the same average kinetic energy, it not that average energy of the particles is dependent on the molecular mass of the particle.
Answer:
i am not so sure
Explanation:but you r beautiful
Answer:
I think its not A Or B So then its gonna be c or d and my guess is C
Explanation:
A polar molecule<span> has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from </span>polar<span> bonds arranged asymmetrically. Water (H</span>2<span>O) is an example of a </span>polar molecule<span> since it has a slight positive charge on one side and a slight negative charge on the other.</span>
Answer: Law of Conservation of Mass.
Explanation:
Law of Conservation of Mass states that during a chemical reaction mass neither created nor be destroyed or total mass of the reactants is equal to the total mass of the products in balanced chemical equation.

Total mass on the reactant side :
(Mass of one methane molecule + mass of two oxygen molecules)
=
Total mass on the product side :
(Mass of one carbon-dioxide molecule + mass of two molecules of water):
=
Total mass on the reactant side = Total mass on the product side = 80 u
