the molar mass is how many grams it takes to make a full mole.  The number  in carbon 12 tells us that it takes 12 g to makes a mole, so one half of that would be <u><em>option d, 0.5</em></u>.

Answer:

d. 0.5

Explanation:

A mole is the amount of matter that is present in a certain substance and it is compared or measured against the amount of particles that can be found in 12 grams of Carbon 12, which is the most common isotope of Carbon that can be found in nature, so if a substance has half of the particles as 12 grams of Carbon 12, that means that it is only half a mole, so there are .5 moles of the substance.

Except for the reaction between iron and sulfur, none of the reactions in this
Sloan [31]

he total number of each of the atoms on the left and the right are the same thus the reaction equation is balanced.

<h3>What is the law of conservation of mass?</h3>

The law of conservation of mass states that, mass can neither be created nor destroyed. In view of the law of conservation of mass, the total mass of the reactants on the left-hand side must be the same as the total mass of products at the right hand side.

Thus is the total mass of the reactants and the products are not the same, it then follows that the reaction does not demonstrate the law of conservation of mass. In this case, the total number of each of the atoms on the left and the right are the same thus the reaction equation is balanced.
