No, the biggest star in the universe is UY scuti
Answer: I think its c or d
Explanation:
The answer is: molecular polarity.
Paper chromatography is an analytical method used to separate colored substances.
Substances are distributed between a stationary phase and a mobile phase.
Substances have different chemical structures and because of that, the different polarity, so each molecule have a different solubility in the solvent.
If a substance is very nonpolar, it will not dissolve at all in a very polar solvent.
If water (polar substance) is a solvent, the more polar the color, the higher it will rise on the papers.
Which diagram? There isn’t any there lol
Solubility of barium chloride at 30 degree Celsius is 38.2g /100 g water and solubility of barium chloride at 60 degree Celsius is 46.6 g / 100 g water.
The quantity of barium chloride that is dissolved in water at 30 degree Celsius = 38.2 * [150/100] = 57.30 g.
The quantity of barium chloride that will be dissolved in water at 60 degree Celsius = 46.6 * [150/100] = 69.90 g
The difference between these quantities is the amount of barium chloride that can be dissolved by heating the barium chloride to 60 degree Celsius.
69.90 - 57.30 = 12.60 g. Therefore, 12.60 g of barium chloride can still be dissolved in the water by heating the water to 60 degree Celsius.
