Chemistry

Answer:

A is correct...B and C wrong I believe

Explanation:

So basically the reason A should be correct is because all enzymes do is provide alternative mechanisms for reaction to proceed and in that alternative mechanism the activation energy is lowered allowing the reactions to progress at greater speeds.

So A makes sense because The aerodynamic shape of a car, like an enzyme, does not supply energy to the car, but it can make it easier for the car to move (basically like an enzyme the car's shape is allowing the car to move faster... enzymes are not consumed in a reaction; they simply help it to occur.)

B is not correct because enzymes do not provide energy for reaction to occur. All they provide is an alternate mechanism where the activation energy is lowered so the reactions can occur at greater rate.

C is not correct because some reactions can occur without enzymes its just that they will occur at a much slower speed.

Hope this helps! I think this should be correct plz double check with your friends.

7. Write a formula for each of the following:

sergeinik [125]

Answer : The formula for each of the following is:

(a) $C_{22}H_{46}$

(b) $C_{17}H_{34}$

(c) $C_{13}H_{24}$

Explanation :

Alkanes are hydrocarbon in which the carbon atoms are connected with single covalent bonds.

The general formula of alkanes is $C_n H_{2n+2}$ where n is the number of the carbon atoms present in a molecule of alkane.

Alkenes are hydrocarbon in which the carbon atoms are connected with double covalent bonds.

The general formula of alkenes is $C_n H_{2n}$ where n is the number of the carbon atoms present in a molecule of alkene.

Alkynes are hydrocarbon in which the carbon atoms are connected with triple covalent bonds.

The general formula of alkynes is $C_n H_{2n-2}$ where n is the number of the carbon atoms present in a molecule of alkyne.

(a) An alkane with 22 carbon atoms

Putting n = 22 in the general formula of alkane, we get the formula of alkane as, $C_{22}H_{2(22)+2}$ or $C_{22}H_{46}$

(b) An alkene with 17 carbon atoms

Putting n = 17 in the general formula of alkene, we get the formula of alkene as, $C_{17}H_{2(17)}$ or $C_{17}H_{34}$

(c) An alkyne with 13 carbon atoms

Putting n = 13 in the general formula of alkyne, we get the formula of alkyne as, $C_{13}H_{2(13)-2}$ or $C_{13}H_{24}$

What happens to the temperature and density of the material between points B and C?

makvit [3.9K]

Answer:

Temperature decreases and density increases

Explanation:

Let us remember that density of a material increases as the temperature of the material decreases. So the cooler a material becomes, the denser it becomes also.

Between points B and C, the material rapidly cools down and the temperature decreases accordingly. This ultimately results in an increase in density since cooler materials are denser than hot materials.
