231.75 because 3.09 (gas price) times 75 equlas 231.75
Bromine and Iodine are both
totally soluble in mineral oil because these substances are all made up of
non-polar molecules. And because water is a polar molecule, Bromine and Iodine
is not soluble in it.
Non polar solvents contain
bonds that have similar electronegativity, an example of this is carbon and
hydrogen such as gasoline. Some other examples are pentane, hexane, benzene
and toluene.

Answer:

Explanation:
The heating process is modelled after the First Law of Thermodynamics:

The specific heat of the aluminium can is:



Answer:
0.0107 mol
Explanation:
Multiply concentration by volume (in liters) to get moles.
0.5 M • 0.0213 L = 0.0107 mol
Answer:
a) 3.98 x 10^-10
Explanation:
Hello,
In this case, for the given pH, we can compute the concentration of hydronium by using the following formula:
![pH=-log([H^+])](https://tex.z-dn.net/?f=pH%3D-log%28%5BH%5E%2B%5D%29)
Hence, solving for the concentration of hydronium:
![[H^+]=10^{-pH}=10^{-9.40}\\](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-pH%7D%3D10%5E%7B-9.40%7D%5C%5C)
![[H^+]=3.98x10^{-10}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D3.98x10%5E%7B-10%7DM)
Therefore, answer is a) 3.98 x 10^-10
Best regards.
