Hey there!:
HA <=> H⁺ + A⁻
pH = -log[H+] = 6
[ H⁺ ] = 10^-pH
[ H⁺] = 10 ^ -6
[ H⁺ ] = 0.000001 M
Percent dissociation:
[ H⁺ ] / [ HA]o * 100
[ 0.000001 / 0.10 ] * 100
0.00001 * 100 => 0.0010%
Answer D
Hope that helps!
Answer:
Higher molar mass compounds will be less soluble than lower molar mass molecules of the same type.
Explanation:
Bigger Mass = slower/less soluble
Small Mass = faster/more soluble
They are all layers of the atmosphere that exist as separate layers but cooperate with each other. The hydrpsphere is the water part of the atmosphere such as oceans, sea, and lake's. The lithosphere is the under earth action that is happening where such things as faults, and volcanoes occur. The biosphere is where all life exist such as me, you, and animals.
<u>Answer:</u> The correct answer is option A.
<u>Explanation:</u>
Nuclear fission reactions are a type of nuclear reactions in which larger nuclei breaks apart into two or more smaller fragment releasing alpha, gamma of beta particles.
There are 3 types of particles that can be released during this process:
1. Alpha particles: These particles are released when a nuclei undergoes alpha-decay process.
2. Beta particles: These particles are released when a nuclei undergoes beta-minus decay process.
3. Gamma radiations: these radiations are released when an unstable nuclei gives off excess energy by a process of spontaneous electromagnetic process.
Hence, any of these particles can be released during the process of fission reaction with smaller atoms.
Therefore, the correct answer is option A.
Hidrogen gas is a diatomic gas, this is H2, which means that one molecule of gas has two atoms (every molecule of hydrogen gas consists in H2).
The particles in gases are the molecules, not atoms.
So, every molecule is a particle, and when you are told that you have 1 mole of hygrogen gas means that you have 1 mole of H2 molecules which is the same that 1 mole of particles.
Therefore, the answer is one mole.
