Answer:C
Explanation:
It would be the most visually understandable.It would be easyer to understand what you are modeling.
Air is a mixture of elements which are formed my atoms that forms molecules. Hope that helps!
Explanation:
This is the photosynthesis equation in which green plants manufacture their food.
During photosynthesis, green plants combine carbon dioxide with water to produce glucose and oxygen gas.
The equation is as shown below:
6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂
This reaction is a typically balanced equation and by all means, we must have the same number of moles of reactants and products.
Solving:
Reactants Products
Elements Number of moles Number of moles
C 6 6
H 12 12
O 18 18
Using the coefficients, one should be able to determine the number of moles of each element.

Formula for molarity is
Molarity=moles of solvent/solution in liters
In given data
NaOH is 21.2g which is needed to be convert in moles first
As no.of moles=mass in gram/molar mass
Molar mass of NaOH is 39.997g/mol
Putting in formula for mole.we get
No of mole = 21.2g/39.997gper mole
= 0.530mole
Now put these values in molarity equation, we get
Molarity =moles of NaOH/ solution in liter
= 0.530/7.92
=0.067M NaOH
