Answer:
8o/58*6*10power23 gives u the answer. molecules=moles*avagadrono
moles=weight/molecular wt
hope u understandmark me as branliest
Answer: Im thinking the answer Is B) Bar graph?
Explanation:
First we must write a balanced chemical equation for this reaction

The mole ratio for the reaction between
and
is 1:2. This means 1 moles of
will neutralize 2 moles
. Now we find the moles of each reactant based on the mass and molar mass.



The
was enough to neutralize the acid because 18.87:39.67 is the same as 1:2 mol ratio.
5CO2 should be in the blank spot.
the reaction would be 7
Yeah, it would be B (1.2 x 102 m^3) because the measurement gave it away even though other numbers were higher, however, the measurements for those were smaller in size.
