Answer:
Grignard reagents are formed by the reaction of magnesium metal with alkyl or alkenyl halides. They're extremely good nucleophiles, reacting with electrophiles such as carbonyl compounds

hope this helps!
Answer:
This question is incomplete but the completed question is in the attachment below. And the correct is b
Explanation:
Specific heat capacity can be defined as the amount of heat required to raise to raise 1 kg of a substance by 1 kelvin. Thus, this means that when the specific heat capacity of a substance is high, it takes more energy to increase the temperature of that substance. This also means that when different substances are subjected to the same amount of heat, the substance with the higher specific heat capacity will absorb less heat; for example at a beach, water has a very high specific heat capacity, thus when the sand in the beach is hot, the beach water is still relatively cold.
From the description above, <u>it can be seen that the metal with the least specific capacity will absorb the greatest amount of heat, thus the metal is lead</u> with the specific heat capacity of 0.129 J/(g. °C).
Materials are transferred between individual cells and their internal environment through the cell membrane by diffusion, osmosis, and active transport. During diffusion and osmosis, molecules move from a higher concentration to a lower concentration. Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. This would be the diffusion.
To determine the time, we can simply do dimensional analysis from the given values. We are given the distance the fluid travels per sec and we are given the required distance to travel. Therefore, we simply divide the required distance with the rate given. It is important to take note with the units.
t = .01 m / .001 m/s = 10 s
OMG yessss that is so cute she will totally accept
