Answer:

The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate  into 355 mL of water is 0.9881M

Molarity of solution is the ratio of the number of moles of the substance to the volume.

n is the number of moles of the compound

Mass of calcium nitrate = 54.3g

Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol

Get the required molarity;

Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate  into 355 mL of water is 0.9881M

jenyasd209 [6]

Personally, I would prefer less memory and live a happier life. Let me explain why, my life is very beautiful and I am very grateful for that. However, there are many things I want to forget and erase from my memories. For example: My parents are very great, I couldn't have asked for better parents. But, my mother specifically gets easily irritated very easily, you have to treat her as if you were holding porcelain in your hands. And, there are many things that my mother has done to me that over the course of time I have not forgotten. And, even though I am no longer resentful, thinking of the past still brings back bad memories I wish I could forget. My mother is very harsh when she punishes, even for minor acts of imperfections. Sometimes, I want to forget everything from the past and even things from the present because living with family members who don't share your same beliefs isn't easy.

The process where two monomers chemically combine to form a larger polymer is called
Norma-Jean [14]

Polymerization is the process where two monomers chemically combine to form a larger polymer.

Given that in the process where monomers chemically combine to form a larger polymer.

We are required to tell the name of the process where two monomers chemically combine to form a larger polymer.

The name of the process is polymerization.

Polymerization is basically the process to create polymers. These polymers are then processed to make different kinds of plastic products. During polymerization many smaller molecules, called monomers or building blocks, are chemically combined to create larger molecules or a macromolecule.

Hence polymerization is the process where two monomers chemically combine to form a larger polymer.

Let h(x) = 2x + 5 and g(x) = 8 - 3r. What is the value of h(g(1.5))?​
balandron [24]
<h3>Answer: 12</h3>

===================================

Explanation:

First lets compute the value of g(1.5)

Plug x = 1.5 into the g(x) function

g(x) = 8 - 3x

g(1.5) = 8 - 3*1.5  <<--- note how every x is replaced with 1.5

g(1.5) = 8 - 4.5

g(1.5) = 3.5

We ultimately want the value of h(g(1.5)), but that is the same as h(3.5) because we found g(1.5) = 3.5; effectively, g(1.5) and 3.5 are the same value.

Let's compute h(3.5) by plugging in x = 3.5 into the h(x) function.

h(x) = 2x + 5

h(3.5) = 2(3.5) + 5

h(3.5) = 7+5

h(3.5) = 12

h(g(1.5)) = 12 which is the final answer

----------------

An alternative track is to first figure out what h(g(x)) would be in general, by first doing this

h(x) = 2x + 5

h(g(x)) = 2*( g(x) ) + 5  <<---- every x replaced with g(x)

h(g(x)) = 2*( 8-3x ) + 5 <<---- the g(x) replaced with 8-3x

h(g(x)) = 16 - 6x + 5

h(g(x)) = -6x + 21

From here, we plug in x = 1.5

h(g(x)) = -6x + 21

h(g(1.5)) = -6*1.5 + 21

h(g(1.5)) = -9 + 21

h(g(1.5)) = 12 which is the same answer as before
