But global warming has changed some of the underlying variables that make wildfires more or less likely to occur every year. Warmer temperatures increase the likelihood that fires will burn more intensely. They also cause snow to melt sooner, and lead to drier soils, forests, and plants, which act as kindling.Sep 8, 2020

What compound is formed when methyloxirane (1,2-epoxypropane) is reacted with ethylmagnesium bromide followed by treatment with
Pavlova-9 [17]

Answer:

Pentan-2-ol

Explanation:

On this reaction, we have a <u>Grignard reagent</u> (ethylmagnesium bromide), therefore we will have the production of a <u>carbanion</u> (step 1). Then this carbanion can <u>attack the least substituted carbon</u> in the epoxide in this case carbon 1 (step 2). In this step, the epoxide is open and a negative charge is generated in the oxygen. The next step, is the <u>treatment with aqueous acid</u>, when we add acid the <u>hydronium ion</u> (H^+)  would be produced, so in the reaction mechanism, we can put the hydronium ion. This ion would be <u>attacked by the negative charge</u> produced in the second step to produce the final molecule: <u>"Pentan-2-ol".</u>

See figure 1

I hope it helps!

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.

Calculating molarity using solute moles A chemist prepares a solution of sodium chloride (NaCl) by measuring out 6.89 mol of sod
hram777 [196]

Answer: Concentration of the chemist's sodium chloride solution is 34.4 mol/L.

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

n= moles of solute

V_s = volume of solution in ml

Given : moles of NaCl = 6.89

volume of solution = 200 ml

Putting in the values we get:

Molarity=\frac{6.89\times 1000}{200}=34.4mol/L

Thus the concentration of the chemist's sodium chloride solution is 34.4 mol/L.
