part c please
Lewis base Correct A Lewis acid is an electron pair acceptor. B has an incomplete octet in BF, and, as an electron deficient species, is an electron pair acceptor in the reverse reaction, so Lewis acid. bis (CH), a Lewis acid or a Lewis base? Lewis acid • Lewis base Correct A Lewis bus is an electron pair donor. The batom in (CH), has two lone pairs and is an electron pair donor in the reverse reaction,...
help please asap
this was all that was given within the problem please someone help
asap.
C If you place 1.1 g of the complex in a 69.5 ml flask at 125 °C, what is the total pressure in the flask at equilibrium? What are the partial pressures of the Lewis acid, the Lewis base, and the complex?
