Hc2h3o2(aq) + ba(oh)2(aq) + > h2o(l) + ba(c2h3o2)(aq)
balance this equation and determine how many moles of ba(oh)2 are required to completely neutralize 0.461 mole of hc2h3o2.

0.461 moles of

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

According to stoichiometry;

2 moles of require = 1 mole of

Thus 0.461 moles of require = moles of

Thus 0.230 moles are required to completely neutralize 0.461 moles of

not clear

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
