Zinc is amphoteric which means it reacts with both acids and alkalis.
The balanced equation is: Zn + 2NaOH + 2H2O --> Na2Zn(OH)4 + H2(g).
Sodium zincate and hydrogen gas are the products.
I would say letter C.
"the oxygen atom<span> attracts </span>electrons<span> a bit </span>more<span> strongly </span>than the hydrogen atoms. The unequal sharing of electrons<span> gives the </span>water<span> molecule a slight </span>negative charge<span> near its </span>oxygen atom <span>and a slight </span>positive charge<span> near its </span>hydrogen atoms<span>."

Answer: Plaster of paris cast
Explanation:
Calcium sulphate,CaSO4, is a odourless, white powder or a colourless, crystallines solid.It exists in as different hydrates: anhydrous(CaSO4), dihydrate(CaSO4.2H2O) and hemihydrate(CaSO4. 1/2 H2O).
The main use of calcium sulphate,specifically in hospitals,is plaster of paris cast.The powdered form of CaSO4 can be formed into a moldable paste upon hydration.
By the process of Nuclear Fission:
1) We Generate Electricity. - If the process is controlled, then we can do this. It's very better way to generate electricity. 'cause of it's many advantages, all nation wants to enhance their electricity production through this mean.
2) We Create explosive. - Again, with the help of nuclear fission we can create certain helpful bombs like Atom Bomb which will help us in war.
Hope this helps!
