Answer:A- It is important to keep the developing chamber covered with plastic wrap during the development of the chromatogram so the solvent vapor can saturate the air in the chamber, the solvent does not evaporate and the chromatogram develops properly and shows the correct cations present.
Well even though im not giving you the whole answer, Im going to tell you what to do in order for you to do it. The main thing you need to do is to determine the delta H and delta S for the reaction.<span>Then subtract the reactants from the products.
On eexample of this is: </span><span>Delta H = (-634.9(CaO)+-393.5(CO2)) - (-1207.6 (CaCO3)) = 179.2 kJ
</span><span>Do the same thing for Delta S but make sure you use the correct units. Delta S is in Joules so you may need to convert. Once you have those values, plug into the equation
</span><span>Delta G= Delta H - T * Delta S
</span>And you will get your result
hope this is very useful for you

Explanation:
water is an ionizable compound, which when being ionized forms a structure, called OH- hydroxyl, when it is ionized it acquires the ionic binding capacity with other chemical compounds.
Answer:
may be exchanged for equity securities.
Explanation:
Convertible bonds -
It refers to the type of bond which can easily be converted to stocks .
It refers to as the fixed - income debt security which can give the interest payments and can be converted to some predetermined number of equity shares and common stock , is referred to as convertible bonds .
The process of conversion can be done at any time period of the bond .
Hence , from the given information of the question ,
The correct answer is may be exchanged for equity securities.
Answer: The percent yield for the 
is, 86.7 %
Explanation : Given,
Moles of 
= 2.36 mol
Moles of = 6.14 mol
First we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 2 moles of react to give 6 moles of
So, 2.36 moles of react to give 
mole of
Now we have to calculate the percent yield for the .
Experimental yield = 6.14 moles
Theoretical yield = 7.08 moles
Now put all the given values in this formula, we get:
Therefore, the percent yield for the is, 86.7 %
