Answer:To speed up the rate of hydrogen production
Explanation:
In the preparation of Hydrogen from the action of dilute acid on zinc metal, few drops of Copper(II)tetraoxosulphate(VI) solution is added to speed up the rate of production.
The hydrogen produced is shown in the equation below
Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
Thus, Copper(II)tetraoxosulphate(VI) solution, a catalyst is used to speed up hydrogen production.
B.soda water
C.milk
D.mud
Is my definition right?
Answer : When the forces are acting in the same direction of movement of the object it can be said as sum of the two individual forces will be equal to the "NET FORCE" .
Example : If two forces (2 kids pushing in the same direction to move the object big box) act on an object(big box) in the same direction, then the net force is equal to the sum of the two forces.
