The rate of movement increases, as they get faster with more energy.
Answer:
c.)the reactants have the same mass as the products
Explanation:
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Answer: The average kinetic energy is proportional to the absolute temperature of the gas. Gas particles are in random motion. Gas particles have no volume. And the collisions between gas particles are elastic.
Explanation: I heard this question before, I think. Hope this helps!
An atom. An atom has no charge. The number (and charge) of protons in atom's nucleus is balanced by the electrons orbiting the nucleus. If it had charge it would be called an ion.
1) In <span>dithionite anion (S</span>₂O₄²⁻) sulfur has oxidation number +3, because oxygen has oxidation number -2, so:
2 · x + 4 ·(-2) = -2.
2x = +6.
x = +3; oxidation number of sulfur.
In sulfur(IV) oxide (SO₂), sulfur has oxidation number +4, because oxygen is again -2 and compound has neutral charge:
x + 2 · (-2) = 0.
x = +4.
Change in sulfur is from +3 to +4.
Sulfur atoms lose electrons in the reaction. Sulfur is oxidized in the reaction, because his oxidation number raise from +3 to +4.
