I really don’t know the answer, please help this kiddo with his question
Answer:
The answer is the solution containing the 90g of water.
Explanation:
Because both solutions have the same amount of the sodium chloride, the concentration would be the same if they both had the same amount of water.
Because the second solution has less water, there is more of the sodium chloride per each drop of water.
I hope this helps :)
<u>Answer:</u> For the given reaction, the value of
is greater than 1
<u>Explanation:</u>
For the given chemical equation:

The expression of
for above equation follows:
![K_c=\frac{[Ca^{2+}]\times [CO_3^{2-}]}{[CaCO_3}]\\\\K_c=[Ca^{2+}]\times [CO_3^{2-}]](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCa%5E%7B2%2B%7D%5D%5Ctimes%20%5BCO_3%5E%7B2-%7D%5D%7D%7B%5BCaCO_3%7D%5D%5C%5C%5C%5CK_c%3D%5BCa%5E%7B2%2B%7D%5D%5Ctimes%20%5BCO_3%5E%7B2-%7D%5D)
The concentration of pure solids and pure liquids are taken as 1 in equilibrium constant expression
As, the denominator is missing and the numerator is the only part left in the expression. So, the value of
will be greater than 1.
Hence, for the given reaction, the value of
is greater than 1
