You would weigh the zinc with a weight, Zinc is a mineral so wether it's a solid or a liquid you would measure it with a zinc.
Answer:
figure is attached
Explanation:
When we treat alcohol with H₂SO₄ we get elimination as the major product.
As we can see in the given reaction that in step 1 the lone pair of electrons of oxygen attached to the alcohol make a bond with the hydrogen of H₂SO₄.
In the 2nd step H₂O gets detached from the parent ring which generated a positive charge on the ring.
In the 3rd step elimination of hydrogen from the carbon next to the carbonium carbon results into formation of an alkene.

Explanation:
Molecular Weight : It is the sum of atomic weights of each atoms present in the compound.
The molecular weught is measured in atomic mass.unit( amu) or simply"u"
This is calculated by using :
Molecular weight = number of atom x atomic mass of the atom
For H2O
Number of H atoms = 2
Number of O atom = 1
Molecular weight of H2O = 2(mass of H atom) + 1(mass of O atom)
Molecular weight = 2(1.00784) + 15.999
= 18.01558 u
= 18.016 u
Two things that store chemical energy are coal, and wood cause when you have a fire you have to get the chemicals from somewhere to keep your fire live.
Dalton thought that atoms were indivisible particles. But Thomsons discovery of the electron proved that the subatomic particles exist.
