Using the law of conservation of mass, what is the mass, in grams, of the product in the given reaction? Reactant 1 (35 grams)+ Reactant 2 (115 grams) →Product (? grams)

A. 80

B. 140

C. 150

D. 75

The correct option is;

C. 150

Explanation:

By the law of conservation of mass we have that in a closed system, the mass of the items in the system can not be destroyed or created by a physical process or chemical reaction

In the given chemical reaction process we have;

Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product = ((35 + 115) grams)

∴ Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product (150 grams)

The mass of the product = 150 grams.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

the answer is c.) there is a warm front in region a and a stationary front in region b.
