Answer:
Pencil is an element and a heterogeneous mixture
Explanation:
CLOUDS would be one of the interacting parts in a weather system.
Answer:
In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.

H2SO4
oxidation number of hydrogen :- +1
oxidation number of oxygen :- -2
if oxidation number of H2SO4 is x
2x (+1) + x + 4x (-2) = 0
+ 2 + x -8 = 0
x = +6
<u>oxidation number of H2SO4 :- +6</u>
