Explanation:
For ICl²-, the central iodine atom is bonded to the 2 chlorine atoms and has 3 lone electron pairs.
Altogether it has 5 electron domains, which means it is sp3d hybridized. (C)
Smashing the cube into pieces
Explanation:
Smashing the cube into pieces will most likely increase the reaction rate between the manganese oxide and hydrogen peroxide.
The rate of a chemical reaction is a measure of the speed of a chemical reaction.
Some factors that affects the rate of chemical reaction are:
- Nature of the reactants
- Concentration of the reactants or pressure if gases.
- Temperature
- Presence of a catalyst.
- Sunlight(some reactions are light catalyzed)
- The nature of reactants implies the physical state of matter, bond type or surface area exposed of reacting species.
- The surface area exposed is directly proportional to the reaction rate.
- Breaking the cubes into smaller pieces exposes more surface area to the chemical action and the reaction rate increases.

Break down the table into smaller sections. Memories period by period or if you like by group (like halogens or noble gases).
Just say the elements in order everyday 1-10 then when you get those 11-20 and continued.
I think the molecular formula would be CHO.
