Answer:
The salt that is produces is NaBr.
Explanation:
When an acid react with base it form the salt and water. The reaction is also called neutralization reaction because both neutralize each other.
In neutralization reaction equal amount of acid and base react to neutralize each other and equal amount of water and salt are formed. When pH does not reach to 7 its means there is less amount of one of reactant which is not fully neutralize.
Neutralization reactions are also used as first aid. For example when someone is dealing with HCl for cleaning purpose of toilet and get touched. It is advised to neutralize it with soap, milk or egg white.
Example:
Hydrobromic acid when react with the sodium hydroxide, a salt sodium bromide and water are formed.
Chemical equation:
HBr + NaOH → NaBr + H₂O
Properties of Sodium Bromide:
- It is present in the form of colorless crystals.
- It is also present in powder form.
- It is very toxic.
- It is soluble in water.
- It is bitter in taste and also odorless.
Answer:
3 moles
Explanation:
So, approximately 3 moles of NaNO3 can be obtained, by reacting 253 grams of Na2CrO4. Also, the number of moles is a dimensionless quantity.
I think the correct answer from the choices listed above is option A. A refracting telescope is made smaller than a reflecting telescope because small lenses cause less distortion in images than big lenses. <span> They are not subject to chromatic aberration because reflected light does not disperse according to wavelength.</span>
