Zinc metal (Zn) reacts with sulfur (S) to create zinc sulfide (ZnS), and the chemical reaction is: Zn (s) + S (s) = ZnS (s).
Importance of Zinc (Zn) and sulfur (S):
- Zinc(Zn) is a vital element that our systems need to absorb food and nutrients as well as create healthy skin and bones. Zinc(Zn) ions play a crucial role in a number of the body's enzymes.
- Sulfur(S) is a pale yellow, tasteless, brittle solid that is also necessary for life. It is found in many proteins as well as the amino acids cysteine and methionine. It is a trace element found in bone minerals, bodily fluids, and lipids.
Chemical reaction -
In this experiment, heating a zinc(Zn) and sulfur(S) combination causes an interesting chemical reaction. A blinding flash of light, hot sparks, a hissing sound, and a cloud of white smoke in the shape of a mushroom are produced.
Therefore, the following chemical processes are taking place in the reaction: Zn (s) + S (s) = ZnS (s).

How many meters per second was it traveling
U=70 , v= 0, t=35, a=?
v=u+at
0=70+a(35)
-70=35a
a=-2m/s^2
Decelerate 2ms^-2 or acceleration is -2ms^-2
