Answer:
Knowing the mass of chlorine in each mixture will enable you find the empirical formulas that will lead to molecular formulas for the compounds in the mixture.This information will help you determine which mixture has a higher proportion of the compound in question.
Explanation:
In determining the percent composition of a compound in a mixture,mass of a compound will be the first step to be determined.This will then allow you to find mole to mole ratio of all elements in that compound.Having mole ratio information, and mass, it will be possible to find ratio of ions in the compound,and determine the mixture with higher proportion of the compound.
Molecular weight and the empirical formula of the compound will led you to the molecular formula of the compound,that will show you the mole ratios which now you can use to determine proportions of the compound in a mixture.
Answer:
Prokaryotes are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles. Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus that holds genetic material as well as membrane-bound organelles.
Explanation:
Answer:
When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.
Explanation:
Species that have the same number of electrons or the same electronic structure.
Answer:
The mass of the acetic acid is 13.5 g
Explanation:
Given;
weight percent of the acetic acid (ratio of solute to total solution), w/w = 98 %
volume of acetic acid, v = 12.83 mL
density of acetic acid, ρ = 1.05 g/mL
density is given by;
density = mass / volume
mass = density x volume
mass of the acetic acid in 12.83 mL = 1.05 g/mL x 12.83 mL
mass of the acetic acid in 12.83 mL = 13.5 g
Therefore, the mass of the acetic acid is 13.5 g
