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:
"One mole of any gas has a volume of 24 dm3 or 24,000 cm3 at rtp (room temperature and pressure). This volume is called the molar volume of a gas."
Explanation:
Divide the mass of neon.
Hydrogen bonds.

Answer:
The plum-pudding model did not identify a central nucleus as the source of a positive charge.
Explanation:
Sir Joseph John Thomson, most popularly known as J J Thomson. He was a famous scientist who was awarded the Noble prize for Physics for his discovery of the subatomic particle, electron.
He placed his famous model of an atom which is known as plum pudding model. He proposed that the atoms are described as the negative particles that is floating within a soup of the diffuse positive charge.
But the main defect of his proposal was that it did not recognized the presence of a central nucleus as a positive charged source.
