Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water.
D. More collisions occur and the time required for the reaction decreases
This happens because according to collision theory, when energy (in this case, thermal energy) is applied to particles, they move/vibrate more quickly.
Answer : The lewis dot structure includes the lone pair of electrons in any element and is helpful for defining the bond formation using the electrons.
In the molecule of HOI hydrogen is to the left of oxygen; oxygen is in middle and Iodine is at right of oxygen.
The picture is attached for better understanding.
Answer:
is reduced in the reaction
Explanation:
The given reaction is

The oxidation number of
is changed from 

And The oxidation number of
is changed from 

Hence,
is oxidized and
is reduced
Gas, as the particles have the most energy, and thus move the most.
