Class 9 Chapter: Structure of the Atom What are the alpha particles compared to?Why?

1 answer:

7 0

Alpha particles are highly ionising because of their double positive charge, large mass (compared to a beta particle) and because they are relatively slow. They can cause multiple ionisations within a very small distance.

When iron rusts in air iron3 oxide is produced. How many moles of oxygen react with 28.0 mol of iron in the rusting reaction 4fe

Marrrta [24]

This the balanced equation based on the question $4Fe + 3O_2 -\ \textgreater \ 2Fe_2O_3$ .

We then proceed with the following calculations

$28.0molFe*(\frac {3molO_2}{4mol Fe})= 21molO_2$

The answer is $21molO_2$ is produced.
