The chemical reaction is written as:
2Zn + O2 = 2ZnO
We are given the amount of the product to be produced from the reaction. We use this value and the relation of the substances in the reaction to calculate what is asked. We do as follows:
2.10 g ZnO ( 1 mol / 81.408 g ) ( 1 mol O2 / 2 mol ZnO ) ( 32 g / 1 mol ) = 0.414 g O2 is needed
The best option is melting point
Answer:
use n=m/M (moles=mass/molar mass) to find out how many moles of C2H6 there are in 60g
Explanation:
Because of its chemical structure.
Yeah...it should be out of your system by then
