Answer:
the number of moles of the gas is 0.00174 mol.
Explanation:
Given;
temperature of the, T = 300 K
volume of the gas, V = 1.45 L
Pressure of the gas, P = 3.0 kPa
The number of moles of the gas is calculated using Ideal gas equation, as follows;
PV = nRT
Where;
n is number of moles of the gas
R is the ideal gas constant, = 8.315 L.kPa/mol.K
n = PV / RT
n = (3 x 1.45) / (8.315 x 300)
n = 0.00174 mol.
Therefore, the number of moles of the gas is 0.00174 mol.
Answer:
Volume and number of moles.
Explanation:
- Gay-Lussac's law was found by Joseph Louis Gay-Lussac in 1808.
- It states that, for a given mass (no. of moles) and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.
So, no. of moles and V are constant.
P ∝ T,
<em>∴ P1/T1 = P2/T2.</em>
- So, the right choice is: <em>Volume and number of moles.</em>
You would have to divide 50/1,000 to get 0.05kg B.
So the answer is 0.05
REDOX is the process whereby electrons are transfered from one specie to another, via oxidation-reduction.
In a chemical reaction, when one specie causes another to gain electrons, it is called a reductant (it gives electrons). This is an oxidation reaction, because it loses electrons of its own. While the other specie goes through reduction from gaining electrons.
Answer:
The answer to your question is: C. A gas turning into plasma.
Explanation:
The plasma state is similar to the gas state, but these to states behave very different.
Like gases, plasma does not have a shape or fixed volume and are less denser than solids and liquids.
But, unlike gases, plasma are made up of atoms in which some of the electrons have been stripped away.
