How many grams of hydrogen gas (H(2)) can be produced from 20 g of Lithium
(MM 7 g/mol)?

While unproven, it uses facts to support part of a conclusion. it is still factual and has predictive power, however.

The correct answer is c. orbital shape. "the angular momentum quantum number l describes the shape of an orbital. it corresponds to each orbital type, i.e. (0,1,2,−1)=(s,p,d,f,g,"

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.
