I think so... I'm currently learning this too but you should be correct
Answer:
The law of the conservation of mass states that matter is neither created nor destroyed, only converted to other forms. Therefore, the mass never changes, even if its appearance does.
Explanation:
Answer:
5.64×10²³ atoms C
Explanation:
Convert moles of H to moles of C:
2.81 mol H × (2 mol C / 6 mol H) = 0.937 mol C
Convert moles of C to atoms of C:
0.937 mol C × (6.02×10²³ atoms C / mol C) = 5.64×10²³ atoms C
It's simple, just follow my steps.
1º - in 1 L we have
of
2º - let's find the number of moles.
3º - The concentration will be
But we have this reaction
This concentration will be the concentration of
considering
and
We can replace it
Therefore the
is:
