food cans are coated with tin and not with zinc because
a) zinc is costiler than tin
b)zinc has higher melting point than tin
c)zinc is more reactive than tin
d)zinc is less reactive than tin
Answers
Answer:
Food cans are coated with tin and not with zinc because zinc is above the tin in reactivity series means more reactive than tin and can react with food elements preserved in it.
Whether zinc has a higher melting point than tin, or tin has a higher melting point than zinc, is of less significance. This is because the food that you keep in the container has much lower temperature than the melting point of the container.
The higher the metal in the series, the more reactive it is and the more vigorously it reacts with water, oxygen and acid. ... Examples for metal-displacement reactions: Zinc can displace copper from copper sulphate solution and iron from ferrous sulphate solution. So zinc is more reactive than iron and copper.
