Answer: The correct option for the chemical equation
is 1.
The correct option for the chemical equation
is 3.
Explanation:
- For the chemical equation:

is a weak acid and hence will not dissociate into ions whereas LiOH is a strong base and will easily dissociate into ions.
The product
is soluble in water and hence, will dissociate into its respective ions. Hence, the ionic equation for this reaction is:

Net ionic equation becomes:

So, the correct option is 1.
- For the chemical equation:

HBr and
are strong acid and strong base respectively, hence they will easily dissociate into ions.
The product,
is is soluble in water and hence, will dissociate into its respective ions. Hence, the ionic equation for this reaction is:

The net ionic equation becomes:

So, the correct option is 3.
Answer: ITS FALSE

If I'm correct the answer should be a series circuit :) Hopefully this helps you out
Answer : The correct option is, (C) 10-mL volumeric pipet.
Explanation :
Graduated cylinder : It is a measuring cylinder that is used to measure the volume of a liquid. It has a narrow cylindrical shape. The marked line drawn on the graduated cylinder shows the amount of liquid that has been measured.
Pipet : It is a type of laboratory equipment that is used to measure the volume of a liquid. It is small glass tube and the marked line drawn on the pipet. It is used to accurately measure and transfer of volume of liquid from one container to another.
Volumetric flask : It is a type of laboratory tool that is also used for measuring the volume of liquid. It is used to make up a solution to a known volume. It measure volumes much more precisely than beakers.
Beaker : It is a type of laboratory equipment that has cylindrical shape and it is used for the mixing, stirring, and heating of chemicals.
As per question, we conclude that the pipet is most precise than other devices because in pipet the marking lines are more accurate. Thus, it can be used to measure volume to precision.
Hence, the correct option is, (C) 10-mL volumeric pipet.
