Answer:

B. A tertiary alcohol; a secondary alcohol

Explanation:

Grignard reagent has a formula RMgX where X is a halogen, and R is an alkyl or aryl group.

Grignard reagent reacts with aldehydes and ketones to form alcohol. However the classification (that is; Primary, secondary and tertiary)  varies depending on which it reacts with.

2-butanone is a ketone.

Ketones reacts with Grignard reagent to form tertiary alcohol

Butanal is an aldehyde.

Aldeyde reacts with grignard reagent to form Secondary alcohol

The answer is; Tertiary alcohol; Secondary alcohol

Answer:

It takes 30 minutes to feel the effects of alcohol.

Explanation:

It may take an hour to metabolize a drink, but it takes approximately thirty minutes before you feel alcohol's effects. This is a good gauge for pacing yourself. Drinking more than one drink every 30 minutes means you are probably drinking too much, too fast.

The force of 75 N must overcome in order to get the truck to start moving. What type of friction must be overcome?
Tamiku [17]

Answer:

Static Friction.

Explanation:

Friction is the force that resists the relative motion between the surfaces sliding against each other.

Static friction is friction between objects that are not in relative motion with each other.

The coefficient of static friction, typically denoted as  μs,

Static friction arises due to surface roughness( relative term)

The static friction force can be overcome by an applied  maximum force

F max =  μs x N

N= normal force

Any force smaller than F max attempting to slide one surface over the other is opposed by a frictional force of equal magnitude and opposite direction.

Any force larger than F max overcomes the force of static friction and causes sliding to occur.

This maximum force is sometimes called the limiting value also. Here that value is 75 N.

200.0 mL of water is added to 300.0 mL of 3.78 M LiClO3, what is the concentration of the resulting solution?
Kamila [148]
Molarity = number of moles/Volume (L). Solve for the number of moles in the initial solution (3.78M = n/0.3 L) and then use that amount of moles and the new volume (0.5 L) to solve for the new Molarity.
