The compound 3-methyl-1-butanethiol, (ch3)2chch2ch2sh, is found in the defensive secretion, or \"spray,\" of striped skunks. dra
w the skeletal structure
1 answer:
Explanation: The given compound is an organic compound because it has hydrogen and carbon atoms in it.
Skeletal structure of an organic compound is defined as a structure which is composed of the skeletal atoms that are used to define a structure.
In organic chemistry, the skeletal atoms are hydrogen and carbon. The atoms other than hydrogen and carbon are termed as heteroatoms and are shown in the structure.
The skeletal structure of 3-methyl-1-butanethiol is given in the image attached.
Here, the functional group is thiol group which has a heteroatom S.

Answer: A) This reaction will be spontaneous only at high temperatures
Explanation:
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
Using Gibbs Helmholtz equation:
Given :
Thus the value of is negative and spontaneous when temperature is high.
This is an incomplete question, here is a complete question.
A weighed amount of sodium chloride is completely dissolved in a measured volume of 4.00 M ammonia solution at ice temperature, and carbon dioxide is bubbled in. Assume that sodium bicarbonate is formed util the limiting reagent is entirely used up. the solubility of sodium bicarbonate in water at ice temperature is 0.75 mol per liter. Also assume that all the sodium bicarbonate precipitated is collected and converted quantitatively to sodium carbonate.
Data to be used for calculating the results
-The mass of sodium chloride in (g) is 14.19
-The volume of ammonia solution in (mL) is 36.15
Calculate the following: What is the theoretical yield of sodium bicarbonate in grams?
Answer : The theoretical yield of sodium bicarbonate in grams is, 20.4 grams.
Explanation :
First we have to calculate the moles of NaCl and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction will be:
From the balanced reaction we conclude that
As, 1 mole of react with 1 mole of
So, 0.243 mole of react with 0.243 mole of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and
is a limiting reagent and it limits the formation of product.
Now we have to calculate the moles of
From the reaction, we conclude that
As, 1 mole of react to give 1 mole of
So, 0.243 moles of react to give 0.243 moles of
Now we have to calculate the mass of
Molar mass of sodium bicarbonate = 84 g/mol
Thus, the theoretical yield of sodium bicarbonate in grams is, 20.4 grams.
