Sodium (na) reacts with chlorine gas (cl2 ) to form sodium chloride (nacl) as shown in the equation: 2na + cl2 → 2nacl if 4 moles of chlorine gas react, how many moles of sodium will react?

Remark

The balance numbers in front of the chemicals tell you how to set up the proportion to solve your question

For every 2 moles Na only 1 mole of Cl2 is required.

Equation

2 moles Na:1 mole Cl2 :: x moles Na:4 moles Cl2

Solution

2/1 = x/4                 Cross multiply

2*4 = x*1

8 = x

Conclusion

8 moles of Na will be used. <<< Answer

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
