Consider the following transient energy balance for a continuously stirred tank with volume v and two feed streams a and b of the same liquid: v(dt/dt)=qa(ta-t)+qb(tb-t)
(a)introduce deviation variables and linearize the differential equation above around the steady state temperatures t_, t_a, and t_b and steady state flow rates q_a and q_b

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
