Chemistry
1 answer:
Alla [95]3 years ago
4 0

Answer:

d). A catalyst lowers the activation energy for a chemical reaction.

Explanation:

From the given choices, it is true that a catalyst lowers the activation energy for a chemical reaction.

The activation energy is the energy barrier that must be overcome before a chemical reaction can occur.

Some reactions have very high activation energy and would not occur without the introduction of a catalyst.

The catalyst brings the reactants into contact by removing the energy deficiency in the system.

How does a heat sink improve cooling inside computers?
amid [387]

Answer:

It does this by using a thermal conductor (usually metal) to carry heat away from the processor into fins that expose a high amount of surface area to moving air. This allows the air to be heated, thus cooling the heat sink and the processor as well.

A group of electrons is treated as a point charge of -1.12 x 10-18 C. How many electrons make up this point charge? Remember tha
Pepsi [2]

Answer:

7

Explanation:

Given that the total charge is given by;

C =nq

Where;

n = number of charges

q = quantity of charge

Where the total amount of charge is  -1.12 x 10-18 C and the magnitude of each charge is  -1.602 x 10-19 C

Then the number of electrons is obtained from;

n =  -1.12 x 10-18 C/ -1.602 x 10-19 C

n = 7
