If you have 3g of sodium and 4g of chlorine what is the total mass of sodium chloride

7g

Explanation:

Given parameters:

Mass of sodium  = 3g

Mass of chlorine  = 4g

Unknown:

Total mass of sodium chloride  = ?

Solution:

This problem entails the direct application of the law of conservation of mass. According to this law, it states that "matter is neither created nor destroyed in the course of a chemical reaction".

So, when sodium and chlorine combines to form sodium chloride, to are expect to produce substance with a mass which adds up to the sum of the reactants;

  Mass of sodium chloride  = mass of sodium + mass of chlorine

                                              = 3g + 4g

                                              = 7g

i believe that it is a exoplanet

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
