Since Janice was given a mixture of alcohol and water, her teacher suggested that she use temperature to separate the two substances. The property demonstrated by the experiment is D. boiling. The boiling point refers to the temperature at which the liquid phase of the substance will turn into vapor. Water is known to boil at 100°C at atmospheric pressure while alcohols are generally known to have a boiling point lower than that of water. In this experiment, knowing that the two substances had a significant difference in boiling temperature was crucial to be able to separate them into their pure substances.
Answer:
The higher the temperature, the faster the particles move, the lower the temperature, the slower.
I believe the answer is D: To show how using a list of examples can strengthen a claim. Dr. King is using these examples to help support his claim, which will help to strengthen it. I hope this helps :)
Hydrogen react with with carbon monoxide(Carbon (ii) oxide) to form methyl alcohol
CO + 2H2 ----> CH3OH
step one calculate the number of moles of H2
= 11g/2.0 g/mol (molar mass of H2 moles = 5.5moles
calculate the moles CO = 37.25grams/28 =1.330moles
The reacting ratio of of H2 to CH3OH 2:1
1.330 x 2/1+2.661 moles of H2 but there is more H2 present than that of co
therefore the grams of CH3OH is threfore =1.330 x32(molar mass of CH3OH) =42.65grams
