Give the common name for the following compound: 2,2-dimethyloct-3-yne CH3-C?C-CH2-CH2-CH2-CH3
Calculate the percentage of chlorine in a sodium hypochlorite powder (disinfectant for pools) if 5.0 kg of powder gives off 2.3 kg of chlorine.
What is the sum of the coefficients in the balanced equation that represents the complete combustion of the relatively new gasoline additive "MTBE," for which the molecular formula is C5H12O?
If you know the answer please give units :) Part A: The reactant concentration in a zero-order reaction was 5.00×10^?2M after 140s and 3.00×10^?2M after 300s. What is the rate constant for this reaction? -> For this I got that 1.25x10^-4M/s, whic..
