Answer:
1 Atm
Explanation:
Dalton's law
The total pressure is 3 Atm so all you have to do is subtract the other partial pressures from 3
Answer:
oxidizer
Explanation:
an example of an oxidizers are oxygen and hydrogen peroxide
B compressed spring I’m pretty sure
Answer:
2.18x10^-9 M
Explanation:
From the question given,
Hydrogen ion concentration, [H+] = 4.59x10^-6 M
Hydroxide ion, [OH-] =?
The hydroxide ion concentration, [OH-] in the solution can be obtained as follow:
[H+] x [OH-] = 1x10^-14
4.59x10^-6 x [OH-] = 1x10^-14
Divide both side by 4.59x10^-6
[OH-] = 1x10^-14 / 4.59x10^-6
[OH-] = 2.18x10^-9 M
Answer:
1. A photon is emitted by the atom.
2. More energy is emitted or absorbed for case 2
Explanation:
The Bohr's model of the atom was based on quantum mechanics idea. He suggested that electrons move in specific spherical orbits round the nucleus.
The claims of his model emphasized on the premise that electrons only move in permissible orbits or energy levels round the nucleus.
The ground state is the lowest energy state available where n= 1.
The excited state is energy levels of n = 2,3,4 .....
Problem 1
For an electron to return to the ground state from a higher energy level, i.e from 5 to 2 in case 1, energy is emitted in form of photons.
Problem 2
More energy is emitted or absorbed when an electron moves from a higher energy level to a more lower one or jumps from a lower energy level to a more higher one.
