Molar mass of lead is 207.2 grams/mole (according to the periodic table)
Molar mass of Sulfate
Sulfur + 4 Oxygen
Molar mass of Sulfur + molar mass of 4 oxygen = 96 grams/mole for sulfate
207.2 + 96.6 = 303.8 grams/mole for Lead(II) Sulfate (I might be .5 grams of, down or up)
Answer:
50%
Explanation:
You would have to do 15 divided by 30 x 100 to get 50
Percentage Yield = Actual Yield divided by Theoretical Yield
Hope this is right and helpful
Answer:
The basic principle of this type of distillation is that different liquids boil and evaporate at different temperatures. So when the mixture is heated, the substance with a lower boiling point starts to boil first and convert into vapors. Let consider a liquid-liquid mixture of A and B where A is more volatile than B this mixture can be separated by the following process:
Explanation
Answer:
Xenon is less reactive.
Explanation:
Xenon is a noble gas with 8 valence electrons whereas bromine is a halogen with 7 and is very reactive.
