The answer would be, A) Polymerization.


Anika [276]4 years ago

Answer: Option (A) is the correct answer.

Explanation:

When monomers in a chemical reaction combine together then it results in the formation of long chains. This process is known as polymerization.

For example, rubber and plastic are formed by polymerization.

Esterification is defined as a process in which esters are formed when an acid is heated with alcohol.

Saponification is defined as a process in which aqueous alkali is heated with a fat or oil resulting in the formation of a soap.

Fermentation is a process in which bacteria like microorganisms, yeast etc help in the breakdown of a substance into simpler substances.

Thus, we can conclude that polymerization is an organic reaction which produces rubber and plastics.

Which of the following halogens has the largest atomic radius?
pickupchik [31]

Answer:

\boxed {\boxed {\sf B. \ Iodine }}

Explanation:

Atomic radius is the measurement from the nucleus to the outer edge of the electron cloud.

As you go down a group (vertically) the atomic radius increases because more electron shells are added. As you go across a period horizontally, the atomic radius decreases.  

If we look at the halogens group (17), we see they follow this order from top to bottom:

F - Fluorine

Cl - Chlorine

Br - Bromine

I - Iodine

Since it increases down the group, iodine  must have the largest atomic radius.

How many moles of H2SO4 are present in 3.63 liters of a 0.954 M solution?
azamat
For this problem, we will use the formula setup for Molarity. 
The formula is M= moles
                               ---------
                                liters

So, lets plug in the numbers we have. We know M= 0.954, and L (liters)= 3.63. Lets plug that into our equation.
                         
                         x
         0.954= -----
                     3.63

As we can see, our moles are unknown.
So, lets multiply 0.954 times 3.63 to get our moles. 
0.954 x 3.63 equals 3.46302.

We know this is our correct answer, because when we divide 3.46302 and 3.63, we get 0.954.

Why?
Because when we divide the moles by liters, we get the molarity.

I hope I helped!!!!!

Here are some common units to know if my units confused you.
M= Molarity, which is what we find by dividing moles by liters
mol= Moles
L= Liters
