Which of the following pairs of reactants will react together to produce water (h2o) as one of the products? fe(oh)3 and cuo cu(oh)2 and h2s mgo and ca(oh)2 so3 and h2o

Your answer is Fe(OH)3 + H2SO4 -> H2O + Fe2(SO4)3 these are not balanced.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
