Question- Combustion of 5.000g of an unknown hydrocarbon resulted in 15.14g of CO2 and 7.751g of H2O. What is the empirical formula of this compound?
PLEASE illustrate all of your steps!! I truly want to know how to work each step of the problem myself. Want to learn and not just get an answer Thank you
How does adding a small amount of a grignard reagent solution to a Grignard reaction help the reaction get started? Hint: The presence of water (moisture) is a major reason a Grignard might not start.
