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

your answers are a,b,,e and f

i hope this

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
