Benzaldehyde or C6H5CHO would not undergo the aldol condensation because it does not contain an alpha-hydrogen in its structure. Aldol condensation is a type of reaction that happens between an enolate and an aldehyde or ketone leading to a alkene that has a planar structure. The lack of an alpha-hydrogen would not allow for it to undergo such process since it cannot enolize. Benzaldehyde undergoes a nucleophilic reaction known as Claisen-Schmidt condensation. It has somehow same mechanism of the aldol reaction however, the nucleophilic attack on the carbonyl happens even without the alpha-hydrogen but with an enolate that is from a ketone.
Answer:
1.728 mg/kg
Explanation:
First have to convert the patient's weight to kg
1 lb = 0.454 kg
185 lb in kg = 83.9 kg
Then we have to divide the dose per the weight of the patient
145 mg for 83.9 kg = 145/83.9
= 1.728 mg/kg
It is know as the normal force.
When a solid is placed on a support, the latter exerts forces on the solid at each point of contact. These are forces that oppose the weight and prevent an object from falling.
This force is usually vertical and upward and often offsets the weight. If the solid is in equilibrium on the support the forces compensate the weight of the solid.
When the disk of the moon mask the the disk of the sun,it creates a (solar) eclipse.
1. The currents in North Pacific gyre rotate more or less clockwise while those of South Pacific rotate counter-clockwise. This is mainly due to the Coriolis effect brought about by the rotation of the earth. Currents above the equator are deflected from west to east while those in the south, east to west.
2. Winds are the main driver of ocean currents because they cause frictional drag on the surface of the oceans in the direction in which the blow. These winds also cause Ekman spirals that are 90 degrees right to the wind direction in the Northern hemisphere and 90 degrees left to the winds in the southern hemisphere.
