The given gives an equation <span>4NH➡ 2N² + 6H². The equation given is not correct since H is not balanced. on the right side,H is counted as only 4 while on the right side, H is 12. The compound on the right should be ammonia, NH3 in order to balance the equation.</span>
First you should know that there is seven oxygen atoms in one Mn2O7
So
2.00 moles of Mn2O7 contain 14.00 moles of oxygen...
Then you multiply this no. with Avagadro no....
from formula
Number of moles= no. of particles/avagadro's no..
14.00×6.02×10²³=84.28 atoms of oxygen...
Answer:
It can enhance survival because the animals for example birds are migrating to those places for high or increasing resources
Explanation:
the cell structure represented by x is the nucleus
As the metal rusts it expands increasing its mass therefore increasing the weight.
