Question

Use the equation below to answer the following questions: Zn(s)+S(s)-->ZnS(s)

1. what are the reactants in this chemical reaction?
2. what is the product?
3.what is the physical state of both the reactants and the products?
4. According to the law of conservation of mass, if the total mass of the product in this chemical reaction is 14g, what must the combined masses of the reactants be?

(i have another if your willing to help me after this one)

Answer 2

please help i do not understand any of this....

Answer 3

Usually, reactants are written on the left of the arrow while products are on the right. In this case, \(\sf Zn\) and \(\sf S\) are reactants and \(\sf ZnS\) is product.

Answer 4

The physical state is written right after each species, e.g. \(s\) for solid, \(l\) for liquid, \(g\) for gas, \(aq\) for aqueous.

Answer 5

According to the law of conservation of mass, the total amount of mass before and after a reaction remains constant. That means if 14g of products was formed, 14g of reactants reacted to produce them.
