Isomer is defined as compounds with the same formula but different arrangement of atoms in its molecule and they differ in their properties. The <span>representation that can be used to show differences between isomers is the use of structural formula. It shows the arrangement of each atoms. It cant be molecular formula and 3D drawing because it does not show the arrangement of the atoms.</span><span>

A) electrolyte the others either describe a process, the opposite, or a whole different thing
87.75 g of fructose
Explanation:
molar concentration = number of moles / volume (L)
number of moles = molar concentration × volume
number of moles of fructose = 1.5 × 0.325
number of moles of fructose = 0.4875 moles
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of fructose = 0.4875 × 180
mass of fructose = 87.75 g

Answer:
CH₂
Explanation:
Given parameters:
Percentage composition:
Carbon = 40.1%
Hydrogen = 6.6%
Unknown:
Empirical formula of the compound = ?
Solution:
The empirical formula of a substance is its simplest formula.
Elements Carbon Hydrogen
Percentage
Composition 40.1 6.6
Molecular mass 12 1
Number of moles 40.1/12 6.6/1
3.342 6.6
Divide through by
the smallest 3.342/3.342 6.6/3.342
1 2
So the empirical formula of the compound is CH₂
