The following statements are correct:
ZINC SULPHATE ARE SOLUBLE IN WATER.
TABLE SALT DISSOLVES IN WATER TO FORM A SOLUTION.
CARBON DIOXIDE GAS WILL BE MORE SOLUBLE IN WATER WHEN THE PARTIAL PRESSURE IS HIGH.
The average atomic mass of Sn is 118.71 g/mol
the percentage of heaviest Sn is 5.80%
the given mass of Sn is 82g
The total moles of Sn will be = mass / atomic mass = 82/118.71=0.691
Total atoms of Sn in 82g = 
the percentage of heaviest Sn is 5.80%
So the total atoms of
= 5.80% X 
Total atoms of
=
atoms
the mass of
will be = 
Answer:
No
Explanation:
The same amount of matter is present before and after chemical and physical changes. Matter cannot be created or destroyed
Unsaturated organic compounds with a carbon-to-carbon double bond and alkynes with a carbon-to-carbon triple bond, as well as aldehydes and ketones with a carbon-to-oxygen double bond, undergo addition reactions.
