Answer:
I believe its A. Mass
Explanation:
An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. For example, the electrical conductivity of a pure substance is a property that depends only on the type of substance. Silver, gold, and copper are excellent conductors of electricity, while glass and plastic are poor conductors.. Other intensive properties include color, temperature, density, and solubility.
Answer:
C
Explanation:
Since they all are 2 mols worth, all you have to do is count the number of atoms in each molecule
H2SO4 contains 2 hydrogen 1 sulfur 4 oxygen = 7 atoms
H2S contains 2 hydrogen and 1 sulfur = 3 atoms
H3PO4 contains 3 hydrogens 1 phosphorus 4 oxygens = 8 atoms
HNO3 contains 1 hydrogen 1 nitrogen and 3 oxygens = 5 atoms
You have the right answer.
Aluminium nitrate is acidic as its made by a weak base with a relatively stronger acid.
Hope that helps ;)
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.
