The answer for the following questions is explained below.

Explanation:

The two variables that affect kinetic energy are:

mass and
velocity

velocity - The faster an object moves,the more the kinetic energy it has.

mass - Kinetic energy increases as mass increases

The kinetic energy of an object depends on both its mass and its velocity

Kinetic energy increases as mass increases

For example,think about rolling a bowling ball and a golf ball down a bowling lane at same velocity

Here,the bowling ball has more mass than the golf ball

Therefore you use more energy to roll the bowling ball than to roll the golf ball

The bowling ball is more likely to knock down the pins because it has more kinetic energy than the golf ball

Why a real diamond that is made in a laboratory under great heat<br> and pressure is not a mineral.

Ierofanga [76]

Answer:

A “Lab Diamond” is just like a Natural Diamond, except instead of growing in the Earth, they grow in a lab. The only chemical difference between Lab Diamonds vs Natural Diamonds is that most Natural Diamonds contain tiny amounts of nitrogen, and Lab Diamonds do not.

Diazomethane, CH2N2, is used in the organic chemistry laboratory despite its danger because it produces very high yields and is

dexar [7]

Answer:

See picture below

Explanation:

You are not providing the starting compound. However, I found a similar question so, I will draw the product of this compound, and then, you follow the same procedure.

As the problem states, the diazomethane is often used in reaction with carboxilic acid. This kind of reaction will do an esterification reaction, and the final product will always result in an esther.

So, with the example I give you here, all you have to do is replace the OH in the carboxilic group of your initial compound, for the OCH₃ group.

See picture below.

Select the term that matches each definition:

Zinaida [17]

Answer:

a) common ion effect

b) solubility

c) saturated solution

d) solubility product constant

e) molar solubility

Explanation:

When a substance, say BA2 is dissolved in a solution and another substance CA2 is dissolved in the same solution. The solubility of BA2 is decreased due to the addition of CA2. This is known as common ion effect.

The mass of a substance that will dissolve in a given Volume of solvent is known as it's solubility.

The molar solubility is the amount of moles of solvent that dissolves in 1 dm^3 of solvent.

A solution that contains just as much solute as it can normally hold at a given temperature is known as a saturated solution.

Lastly, the product of molar solubilites raised to the power of the molar coefficient is know as the solubility product constant.

A car moving at 12 m/s applies its brakes and comes to a stop in 2 s. What was its acceleration?

vredina [299]

Answer:

Explanation:

The acceleration of an object given it's velocity and time taken can be found by using the formula

$a = \frac{v}{t} \\$

where

a is the acceleration

v is the velocity

t is the time

From the question we have

$a = \frac{12}{2} \\$

We have the final answer as

Hope this helps you
