It means that it has to be able to be test in an expermint that your doing
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:
1) first order
2) zero order
3) second order
Explanation:
For a first order reaction, the concentration of the reactants varies exponentially with the rate of reaction. The curve of a first order reaction shows an exponential relationship between the rate of reaction and the change in the concentration of reactants.
For a zero order reaction, the rate of reaction is independent of the concentration of the reactants. So, regardless of the amount of reactant in solution, the rate of reaction is constant.
For a second reaction, the reaction rate increases in direct proportion to the concentration of the reactant in solution.
If the equation is not balanced, you have extra of one substance. If you try to do an experiment, you could wind up with a totally different outcome. Its kind of like baking a cake. If the ingredients aren't the right amounts, you dont get an edible cake.
