Cathode rays are made up of negatively charged particles.
Atoms contain negatively charged particles.
Explanation:
The experiment carried out by J.J Thomson provided evidence to support that fact that atoms contains negatively charged particles and that cathode rays are negatively charged.
J.J Thomson performed experiments using a gas discharge tube.
- Through his experiment, he discovered cathode rays.
- From his observation, he noticed that they were attracted to the another so they must be negatively charged.
- He called the rays cathode rays.
- Today, they are known as electrons.
- Thomson's experiment discarded the widely held believed that atoms are indivisible.

Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, 10L of H₂S should react with 6.6L of oxygen at stanadard pressure and temperature.
<h3>
What is ideal gas equation?</h3>
Ideal gas equation is the mathematical expression that relates pressure volume and temperature.
Mathematically the relation between Pressure, volume and temperature can be given as
P×V=n×R×T
where,
P = pressure of gas
V= volume of gas
n =number of moles of gas
T =temperature of gas
R = Gas constant = 0.0821 L.atm/K.mol
At Standard temperature and pressure, 2 moles of H₂S react with 3 moles of 0₂. S0, 10L of H₂S should react with 0.66×10=6.6L of oxygen.
Therefore, 10L of H₂S should react with 6.6L of oxygen.

The 3 common gases that give off reactions are Hydrogen sulfide, Carbon monoxide, Nitrogen oxides.
<h3>What are off reactions</h3>
Off reactions are defined as chemical reactions that occurs when something burns or during combustion of materials which gives off energy.
Some gases that give off reaction are:
- Hydrogen sulfide
- Carbon monoxide
- Nitrogen oxides
Note that these gases are mostly poisonous.
Therefore, the 3 common gases that give off reactions are Hydrogen sulfide, Carbon monoxide, Nitrogen oxides.
