Gamma rays
Explanation:
Gamma rays is a form of electromagnetic radiation. It has zero mass and no charge.
Most radiations are particles but gamma rays are not particles they are mere rays.
- They have an energy range between 10KeV and 3Mev
- The range of gamma rays is not definite but it is very long.
- The intensity of gamma rays for any medium decreases exponentially from the source.
- Gamma rays are ionizing radiations

Explanation:
An acid is a substance that ionizes to produce excess hydrogen ion in solutions.
- A concentrated acid contains a high amount of hydrogen ions in solution compared to other ions.
- Such solutions usually ionizes completely.
- A dilute solution contains a high proportion of water and with low amount of hydrogen ions.
- They do not ionize easily and as fast as strong acids.
Answer:
HBr + H₂SO₄ → SO₂ + Br₂ + H₂O An oxidizing agent is a substance that itself becomes reduced and oxidizes the other chemical species in the reaction mixture. A reducing agent is similar, except that it becomes oxidized and reduces the other substance. In the reaction, the valency of bromine changes from -1 to 0, so it is oxidized
Explanation:
It is Cobalt(II)chloride dihydrate. The value of x is 2.
First, we have to determine the mass of H₂O that was evaporated upon heating which will be = 2.00g - 1.56 g
= 0.435 g
So,
CoCl₂ + x.H₂O → CoCl₂.xH₂O
Molecular mass of CoCl₂ = 129.839 g/mol
Molecular mass of H₂O = 18 g/mol
Weight of sample after heating = 1.565 g
Weight of H₂O evaporated = 0.435 g
Hence,
x ≈ 2
So, it is Cobalt(II)chloride dihydrate.
