The core of an atom contains protons and neutrons.
<span>(NH4)2SO4(aq) + BaCl2(aq) = BaSO4(s) + 2 NH4Cl(aq)</span>
<span>Reaction type: double replacement</span>
Since protons are postive and neutrons are neutral. Then it is postive.
the molecular formula is calculated as follows
find the mole of each molecule
that is for carbon = 26.7/12= 2.23 moles
hydrogen= 2.24/1=2.24 moles
oxygen= 71.1/16=4.44 moles
find the mole ratio of each element
that is divide all moles by the smallest mole( 2.23)
for carbon=2.23/2.23=1,
hydrogen = 2.24/2,23=1
oxygen= 4.44/2.23= 2
the empirical formula = CHO2
therefore the molecular formula=(CHO2)n=270.1
{ ( 12x 1) + 1x1) +(16x2)}n=270.1
45n=270.1
n=6
molecular formula is therefore=(CHO2)6=C6H6O12
<span>30 protons, 30 electrons is your answer!:)</span>
