Answer:
Approximately
.
Explanation:
<h3>Number of moles of formula units of magnesium sulfate required to make the solution</h3>
The unit of concentration in this question is "
". That's equivalent to "
" (moles per liter.) In other words:
.
However, the unit of the volume of this solution is in milliliters. Convert that unit to liters:
.
Calculate the number of moles of
formula units required to make this solution:
.
<h3>Mass of magnesium sulfate in the solution</h3>
Look up the relative atomic mass data of
,
, and
on a modern periodic table:
Calculate the formula mass of
using these values:
.
Using this formula mass, calculate the mass of that (approximately)
of
formula units:
.
Therefore, the mass of
required to make this solution would be approximately
.
Answer:
Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring.
Answer:
is larger
Explanation:
, where
is the acid dissociation constant.
For a monoprotic acid e.g. HA,
and ![\frac{[A^{-}]}{[HA]}=\frac{K_{a}}{[H^{+}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BA%5E%7B-%7D%5D%7D%7B%5BHA%5D%7D%3D%5Cfrac%7BK_%7Ba%7D%7D%7B%5BH%5E%7B%2B%7D%5D%7D)
So, clearly, higher the
value , lower will the the
In this mixture, at equilibrium,
will be constant.
of HF is grater than
of HCN
Hence, ![(\frac{F^{-}}{[HF]}=\frac{K_{a}(HF)}{[H^{+}]})>(\frac{CN^{-}}{[HCN]}=\frac{K_{a}(HCN)}{[H^{+}]})](https://tex.z-dn.net/?f=%28%5Cfrac%7BF%5E%7B-%7D%7D%7B%5BHF%5D%7D%3D%5Cfrac%7BK_%7Ba%7D%28HF%29%7D%7B%5BH%5E%7B%2B%7D%5D%7D%29%3E%28%5Cfrac%7BCN%5E%7B-%7D%7D%7B%5BHCN%5D%7D%3D%5Cfrac%7BK_%7Ba%7D%28HCN%29%7D%7B%5BH%5E%7B%2B%7D%5D%7D%29)
So,
is larger
