The answer is d. Each of its particles becomes surrounded by water molecules.
Notice that when you dissolve a solid compound in the water, it is no longer visible in or eyes, it mixes in the water, it is because it is being divided into smaller particles and each particles were surrounded by the water molecules.
A. 8,330 --> 8.33 × 10^3
B. 83.3 --> 8.33 × 10^1
C. 0.00833 --> 8.33 × 10^-3
D. 0.0833 --> 8.33 × 10^-2
E. 83,330 --> 8.33 × 10^4

Answer:
See explanation below
Explanation:
This reaction is known as the Grignard reaction. If's often used to add an alkyl to a molecule, in this case, a ketone. This also helps to reduce the carbonile to an alcohol.
The mechanism is taking place in 3 steps.
The first step involves the attack of the pair of electrons of the oxygen from the cyclohexanone to the MgBr, and the other pair takes the propyl.
The second step involves the breaking of this bond to have the OMgBr and the propyl attached to the carbon of the chain.
The last steps involves an hydration of the molecule, to turn the OMgBr into OH, and that would be the final product.
In this case, the final product will be 1-propyl-cyclohexanol.
The picture below, shows the mechanism and the drawing of the final product.

Answer:
D.)more collisions --> greater collision force --> higher pressure
Explanation:
The temperature of an ideal gas is directly proportional to the average kinetic energy of the particles in the gas, according to the equation:
where
KE is the kinetic energy
k is the Boltzmann's constant
T is the absolute temperature of the gas
As a result, when the temperature of a gas increases, the kinetic energy of the particles increases too. This means that overall, they will move faster, therefore there will be more collisions between the particles and the walls of the container. As a result, the particles will exert on average a greater force of collision agains the walls, and therefore, they will exert a higher pressure.
So, the correct option is
D.)more collisions --> greater collision force --> higher pressure
