4) decreases, decrease

Explanation:

If the weight of an object decreases the mass of the object decreases. Weight is a form of force that acts under the acceleration due to gravity.

       Weight = mass x acceleration due to gravity

Acceleration due to gravity on earth is a constant value of 9.8m/s²

 from the problem, we see that mass is directly proportional to the weight of an object.

If the weight increases, the mass increases. If the weight increases then mass will increase.

Citrus2011 [14]
10 / (7.89) (2) 

molarity equation is M = Moles of solute / Liters of solution

7.89 = Moles of solute / 2

(7.89)(2). The question asks for the molar mass which is defined as g/mol. Dividing would give you the unknown compound.

In a metabolic pathway, succinate dehydrogenase catalyzes the conversion of succinate to fumarate. The reaction is inhibited by
Tom [10]

Answer:

B. Succinate is the substrate, and fumarate is the product in the reaction.

Explanation:

The substrate is the reactant, i.e. the compound that is being acted upon in the reaction. In this case, the substrate is succinate.

The enzyme is the compound that is doing the catalysis, in this case it is succinate dehydrogenase.

The product is what is made by the reaction, in this case it is fumarate

A non-competitive inhibitor is one that reduces the activity of the enzyme regardless of whether or not it has already bound the substrate. This is not true for this reaction, as the inhibitor - malonic acid - acts as a competitive inhibitor, in the presence of more succinate acid, its effects are reduced.

Therefore, the correct answer is B.

Give regents and mechanism
Kryger [21]

Answer:

Reagents: 1) BH_3 2) H_2_O2, OH^-

Mechanism: Hydroboration

Explanation:

In this case, we have a <u>hydration of alkene</u>s reaction. But, in this example, we have an <u>anti-Markovnikov reaction</u>. In other words, the "OH" is added in the least substituted carbon. Therefore we have to choose an anti-Markovnikov reaction: <u>"hydroboration"</u>.

The <u>first step</u> of this reaction is the addition of borane (BH_3) to the double bond. Then in the <u>second step</u>, we have the deprotonation of the hydrogen peroxide, to obtain the peroxide anion. In the <u>third step</u>, the peroxide anion attacks the molecule produced in the first step to produce a complex compound in which we have a bond "BH_2-O-OH". In <u>step number 4</u> we have the migration of the C-B bond to oxygen. Then in <u>step number 5</u>, we have the attack of OH^- on the O-BH_2 to produce an alkoxide. Finally, the water molecule produce in step 2 will <u>protonate</u> the molecule to produce the alcohol.

See figure 1

I hope it helps!
