Answer:

A. 1.54 mole.

B. 55.39g of carbon

Explanation:

A. Determination of the number of mole in 67.7g of C3H8.

Mass of C3H8 = 67.7g

Molar mass of C3H8 = (3x12) + (8x1) = 44g/mol

Number of mole of C3H8 =..?

Number of mole = Mass/Molar Mass

Number of mole of C3H8 = 67.7/44

Number of mole of C3H8 = 1.54 mole

B. Determination of the mass of carbon in the compound.

This is illustrated below:

The mass of C in compound can be obtained as follow:

=> 3C/C3H8 x 67. 7

=> 3x12 / 44 x 67.7

=> 36/44 x 67.7

=> 55.39g

Therefore, 55.39g of carbon is present in the compound.

What can be said of a closed system when an exothermic reaction proceeds in an aqueous solution?
lyudmila [28]
An exothermic reaction is a type of reaction that dissipates heat as the reaction proceeds. This would mean that in a closed system, when a reaction proceeds and is endothermic, the temperature of the solution  or the system would increase so as to maintain the equilibrium with the whole system.

Nitriles can be converted into carboxylic acids. how would you use ir spectroscopy to monitor the progress of this reaction?
Lady bird [3.3K]

Fats or oils are created when the hydroxide group of glycerol combines in a dehydration synthesis process with the carboxyl group of fatty acids.

<h3>What is dehydration ?</h3>

Your body loses more fluids when you are dehydrated than you are taking in. If unattended to, it could get worse and become a serious problem.

When you don't drink enough water or lose more than you take in, you become dehydrated. Sweat, tears, vomiting, urination, and diarrhea all cause fluid loss. Climate, level of physical activity, food, and other variables can all affect how severe dehydration is.

Dark urine, decreased urination, headaches, weariness, dry skin, decreased skin turgor, and poor focus are all indicators of dehydration.

How many federal agencies are responsible for managing land resources in the United States?
dimulka [17.4K]

The answer would be 4.

The agencies are:

Department of Agriculture's Forest Service (AFS)

Department of the Interior's Bureau of Land Management (BLM)

Fish and Wildlife Service (FWS)

National Park Service (NPS)

These four agencies cover around 95% of the land and are the only federal agencies.

I learned about these agencies in school.
