Why are stoichiometric calculations possible with a balanced chemical equation, but not with a skeleton equation? The coefficients of the balanced chemical equation show mole ratios.

The coefficients of the balanced chemical equation identify the elements that are involved in the reaction.

The coefficients of the balanced chemical equation show mass ratios.

In a balanced chemical equation, the subscripts and superscripts in the chemical formulas show mass ratios and mole ratios.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

the answer to this question is 3.
