methyl salicytate is heated in water, salicylic acid and methyl alcohol form. HOC6H4COOCH3 + H2O --> HOC6H4COOH + CH3OH 4.0mL Methyl Salicitate 40mL of 6M NaOH 50 mL DI 50 mL of 8 M H2SO4 What is the limiting reactant in this experiment? Assume water is the other reactant. The density of methyl salicylate (HOC6H4COOCH3) is 1.18 g/mL at 20 Celsius.
For the next three problems, consider 1.0 L of a solution which is 0.3 M HC2H3O2 and 0.2 M NaC2H3O2 (Ka for HC2H3O2 = 1.8 x 10-5). Assume 2 significant figures in all of the given concentrations so that you should calculate all of the following pH..
What is the pressure in atmosphere of a gas mixture that consit of 0.2 moles of nitrogen and 0.3 mols of oxygen
What is the heat change in J associated with 65 g of gaseous acetic acid at 127 oC changing to solid at -50 oC? c(acetic acid) (g) = 1.11 J/(g.K) c(acetic acid) (liq) = 2.18 J/(g.K) c(acetic acid) (s) = 1.32 J/ (g.K) ?Hfus(acetic acid) = 192 J/g ?..
the carbon-carbon bonds would be alternately long and short. However, to consider the structures as resonance contributors (or to connect them by a double-headed arrow) violates a basic principle of resonance theory.
