“Na2SO3” represents sodium sulfite.What does the 4 mean in the formula 4Na2SO3?
Strike441 [17]

The mass of substance which consists the equal number of particles as 12 grams of Carbon-12 is said to be mole.

For example:

The balanced chemical equation for production of water from hydrogen and oxygen is:

2H_2(g) + O_2(g) \rightarrow 2H_2O(l)

That means 2 moles of H_2 reacts with 1 mole of O_2 to give 2 moles of  H_2O.

The given formula is 4Na_2SO_3.

Hence, 4 represents the number of moles in 4Na_2SO_3 formula that is 4 moles of Na_2SO_3.

The number of atoms of sodium, Na in 4Na_2SO_3 is:

4 \times 2 = 8

The number of atoms of sulfur, S in 4Na_2SO_3 is:

4 \times 1 = 4

The number of atoms of oxygen in, O in 4Na_2SO_3 is:

4 \times 3 = 12

Suggest a way that chemistry knowledge could help you make decisions about a claim
Tanya [424]

Answer and explanation;

-Knowledge of chemistry allows the public to make informed decisions.

-Since chemistry is the basis of everything in life, knowing the basics allows us to make smarter decisions. With a knowledge of chemistry, one can form better opinions about the day’s news. An individual will be able to distinguish the truth from the lies in environmental reporting, and better understand the meaning of a chemical spill.

-One can even better decide what your opinion on public policy should be by using your own knowledge of science rather than trying to figure out which politician or pundit is the least untrustworthy.
