Arock weighing 75.0 g is placed in a graduated cylinder displacing the volume from 31.4 ml to 36.5 ml. what is density of the rock in grams/cubic centimeter?

The limiting reactant or limiting reagent is a  reactant  in a  chemical reaction  that determines the amount of  product  that is formed. identification of the limiting reactant makes it possible to calculate  the theoretical yield  of a reaction.the reason there is a limiting reactant is that elements and compounds react according to  the mole ratio  between them in a balanced chemical equation. so, for example, if the mole ratio in the balanced equation states it takes 1 mole of each reactant to produce a product (1: 1 ratio) and one of the reactants is present in a higher amount than the other, the reactant present in the lower amount would be limiting reactant. all of it would be used up before the other reactant ran out.limiting reactant examplegiven 1 mol of hydrogen and 1 mol of oxygen in the reaction: 2 h2  + o2  → 2 h2othe limiting reactant  would be hydrogen because the reaction uses up hydrogen twice as fast as oxygen.how to find the limiting reactantthere are two methods used to find the limiting reactant. the first is to compare the actual mole ratio of the reactants to the mole ratio of the balanced chemical equation. the other method is to calculate the gram masses of the product resulting from each reactant. the reactant that yields the smallest mass of product is the limiting reactant.

Classification of the elements. the next thing in our review is to classify the elements into three groups. these three groups are: metals, nonmetals, and inert gases. let's look at where these groups are located on the periodic table and correlate them with the ability to lose and gain electrons.

None of the above. it should be 3+, but that's not an option.
