Answer:
Sodium Bromide + Dichlorine = Sodium Chloride + Dibromine
Reaction Type
Single Displacement (Substitution)
Explanation:
Explanation:
Every valid chemical equation must be balanced i.e the same number of atoms must be present on both sides of the equation.
The law of conservation of mass states that "matter cannot be created nor destroyed in a chemical reaction but are transformed from one form to another".
- A chemical equation contains reactants on the left hand side.
- On the right hand side, the products are formed.
- For the reaction to be valid, there must be equal numbers of atoms of any specie on both sides of the equation.
- This way the law of conservation of mass holds true.

When parallel light rays comes across a concave lens, the rays are refracted outwards. Concave lenses are thinner in the middle part. Parallel light rays diverge and seems to appear from one point called the principal focus. The image formed is smaller.
The frequency waves are higher as it approaches, and lower as it goes past.
