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 ![NH_3](/tpl/images/0522/9286/b033f.png)
So, 0.243 mole of
react with 0.243 mole of ![NH_3](/tpl/images/0522/9286/b033f.png)
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![NaHCO_3](/tpl/images/0522/9286/08309.png)
From the reaction, we conclude that
As, 1 mole of
react to give 1 mole of ![NaHCO_3](/tpl/images/0522/9286/08309.png)
So, 0.243 moles of
react to give 0.243 moles of ![NaHCO_3](/tpl/images/0522/9286/08309.png)
Now we have to calculate the mass of![NaHCO_3](/tpl/images/0522/9286/08309.png)
Molar mass of sodium bicarbonate = 84 g/mol
Thus, the theoretical yield of sodium bicarbonate in grams is, 20.4 grams.

It is a mixture because the compounds that make up air e.g. oxygen (o2), Carbon dioxide (co2) and the most important Nitrogen which is an element and makes up 78.09% of air are not chemically bound in the way that compounds are because they can be separated easily and there has been no change in state to any of the compounds or elements in air!hope this helpful!
