BaCl2+K2SO4 => BaSO4+2KCl

Ba(2+) + 2Cl(-) +2K(+) + SO4(2-) => BaSO4+ 2K(+) + 2Cl(-)

Ba(2+) + SO4(2-) => BaSO4

K2CO3+2HCl => 2KCl + CO2 + H2O

2K(+) + CO3(2-) + 2H(+) + 2Cl =>

2K(+) + 2Cl(-) +CO2+H2O

2H(+) + CO3(2-) => CO2+H2O

However, little Lewis was sure the new pupil felt sad inside.
So, one day, he decided to follow the new kid home after school. Lewis
was sure he would see him crying.
The new kid left school and walked to the local park, and there he
