What is the role of the phosphoric acid in asprin synthesis? PROVIDE A MECHANISM which explains the role of this

chemical in this reaction.

---I know that phosphoric acid is needed because it is an acid and as an acid it acts as a catlyst in this experiment. What I do not know is how to provide a mechanism which explains the role of this checmical reaction

22 in 2. The object, which is very similar to the impact pendulum we will discuss, consists of an 8-lb, 22 inch slender bar welded to a 12-lb disk. It is released from rest in the horizontal position 1. Using a computer program, plot the force in the pin at A as a function of θ fro θ= 0 to 90, Partial answer: at θ= 450, A= 37.73 lbs, CM is 20.6 inches from A (you must prove this). 5 in

The general form of the continuity equation for incompressible flow is ∂u/∂x+∂v/∂y+∂w/∂z=0. Simplify this equation for the given scenario (Figure 1) and collect all the terms on one side. Use subscripts to represent partial derivatives (for example, ∂u/∂x=ux and ∂2u/(∂x∂y)=uxy). Using this notation, the continuity equation can be written as ux+vy+wz=0. Express your answer in terms of ρ, u, v, w, p, g, and/or μ. Use subscripts to represents partial derivatives.

consider f(x)=z-2z^2. identify the real and imaginary parts of f

Suppose that the function f(z) = u(x,y) + iu(x,y) is analytic in some domain D. we can define two families of curves in D. The equations u(x, y) = q and v(x,y) = c2, where c1 and c2 are arbitrary constants, define the level curves of u and v. These level curves form orthogonal families, i.e. each curve in one family is orthogonal to each curve in the other family. Consider f(z) 222 1. Identify the the real and imaginary parts of f, i.e. the functions u(r, y) and v(x, y). and u(x, y) = c2. given curve, and the Cauchy-Riemann equations, to show that the two 2.
