the equation of line determined from a beer's law plot is y=0.195x+0.4. what is the resistance of an unknown water sample if the assumed concentration is 650ohms.
Given the reaction: 2Al + 3H2SO4 -> 3H2 + Al2(SO4)3 what would be the total number of moles of H2SO4 needed to react completely with 5.0 moles of Al ?
Presume a student used 1.0mL of 2-methylcyclohexanol and 2mL of phosphoric acid in a dehydration reaction. After purification of the reaction product, 0.484 g of a mixture of alkenes was isolated. Explain what is the percentage yield of the dehydr..
Calculate the 'size' of a hydrogen atom in its ground state according to this definition. Go on to explore how the 'size' varies as the definition is changed to other precentages, and plot your conclusion.
