Hi,
Homogeneous mixture 2
Heterogeneous 3

Solution 5
Compound 4
Molecules arranged in regular pattern changes into an irregular pattern
An an increase in
temperature lead to more effective collisions between reactant particles and an
increase in the rate of a chemical reaction because the number of
molecules with sufficient energy to react increases. The answer is number 3.
