Explanation:
Chemical formula of gypsum is 
and it is a soft sulfate mineral that consists of calcium sulfate dihydrate.
Some uses of gypsum are as follows.
- It is used for manufacturing wall board.
- It is used in the manufacture of plaster of paris.
- It is also used as a fertilizer.
Thus, we can conclude that out of the given options, fertilizer, wallboard, and plaster of paris are some uses of the mineral gypsum.
S. Properties can be anything from composition to color to ductility. Without knowing an object's properties, it is impossible to characterize it. For example, looking at some common properties of metals helps to differentiate them from non-metals or metalloids.
Answer:
Option 3 = i.e. If you add the masses of all the products after fission, they are LESS than the mass of the reactants
Explanation:
Nuclear fission: Is the process in which the nucleus of radioactive element with higher mass undergoes fission and get into fragment of smaller mass with release of high energy.
The products of the nuclear fission are the fragment of smaller nuclei.
For example, larger nucleus that of uranium split into two small nuclei along with some neutrons, energy and gamma rays.
The mass of the original atom always more than the sum of the atomic masses of the atoms produce by fission. The reason is neutrons and kinetic energy lost, and upon cooling we get product masses less than original.
Pb(OH)2
This is the formula
Alkanes can, the double bonds mean that something can be added across it
