If the original sample of zn had a mass of 1.4 g, what mass of zncl2 can be produced in the reaction?

Zn is a metal that used several industries and factories for making a regular-use item. Zinc has also been beneficially used in the ecosystem and also helps to make the soil fertile. Zinc is take-up by the plant from soil to increase the shoot growth of the plant.

According to the law of mas of conversation, the mass of the element remains the same before the reaction and after the reaction.

The consumed mass and the produced mass are always the same in the reaction process.

Hence, the amount of zinc has remained the same in the reaction that is 1.4g.
