Explanation:
Mole = 0.5 = n/NA
n = no. of molecule
NA = avogadro number = 6.023x 10^23
so
N/NA = 0.5
N = 0.5 x 6.023 x 10^23
N = 3.0115 x 10^23
A B and C are all chemical changes. paper tearing is not.
Answer: 448 g of
will be required to completely react with 784g moles of CO(g) during this reaction.
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of
require = 1 mole of
Thus 28 moles of
will require=
of
Mass of
Thus 448g of
will be required to completely react with 784g moles of CO(g) during this reaction.
C is the correct answer I think have a good day
