Answer: Nail moving towards a magnet
Explanation: Since the iron nails and pins move towards the magnet, it means that the magnet exerts a force on them. The force exerted by a magnet is called magnetic force.

The air is so dry that when it hits a snowpack, the frozen water evaporates, going directly from the ice to vapor and bypassing the liquid phase entirely. This is called sublimation, and it's a common way for snow to disappear in the arid West."
Answer:There is no change in identity of the substance and we can visually see a substance being drawn into wires. Hence ductility is not a chemical property, it is a physical property. Some examples of ductile materials, include metals such as copper, aluminium, silver, gold, etc.
Explanation:
Answer:
41.56 g
Explanation:
Given data:
Mass of NH₄Cl = 15.50 g
Actual yield of AgCl = 35.50 g
Theoretical yield of AgCl = ?
Solution:
Chemical equation:
NH₄Cl + AgNO₃ → AgCl + NH₄NO₃
Number of moles of NH₄Cl:
Number of moles = mass/ molar mass
Number of moles = 15.50 g/ 53.491 g/mol
Number of moles = 0.29 mol
Now we will compare the moles of NH₄Cl with AgCl .
NH₄Cl : AgCl
1 : 1
0.29 : 0.29
Theoretical yield of AgCl:
Mass = number of moles × molar mass
Mass = 0.29 mol ×143.32 g/mol
Mass = 41.56 g
