Answer:
17.92L or 17.92dm³1
Explanation:
number of moles of a gas = volume of that gas/ 22.4(S.V.P)
0.8 mol = x / 22.4
cross multiplication
x = 22.4 × 0.8
x = 17.92
:. the volume of 0.8 mol of nitrogen gas is 17.92dm³ or 17.92L
1) Chemical equation.
2) Types of reaction.
In the reaction above, we can see that two different compounds get together to form a new compound. <em>This is called a synthesis or a combination.</em>
Decomposition: A compound is broken down into simpler compounds.
Combustion: A compound containing Carbon and Hydrogen combines with oxygen.
Double replacement: Positive and negative ions in two compounds switch places.
By 1920, physicists knew that most of the mass of the atom was located in a nucleus at its center, and that this central core contained protons. In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron
