**chemistry**

If the iodine value obtained for an experiment is negative,could this be due to an experimental error?

**Chemistry**

Write a balanced equation for the formation of boehmite (ALO2H) from aluminium ions and hydroxide ions.

**physics**

What is the magnitude of an electrostatic force experienced by one elementary charge at a point in an electric field where the field intensity is 3.0 x 10^3 newtons per coulomb? a) 1.0 x 10^3 N b) 1.6 x 10^-19 N c) 3.0 x 10^3 N d) 4.8 x 10^-16 N

**science/physics**

I was in a crosswalk, struck by a truck weighing 3,400 lbs. (traveling at about 8 K/hr) - what was the force per square inch exerted on me?

**Chem**

Using this formula.. pH = -log(H^+) find the pH 1.6 x 10^(-5)

**Algebra**

Evaluate the logarithmic function for three values of x between zero and one, three values of x greater than 1, and at x=1. Show your work. Use the resulting ordered pairs to plot the graph. State the domain and the range of the function. g(x) = ln x + 2

**Calculus I**

dR/dt = .3 ohms/s I = 18V/R d/dt(I) = d/dt(18V/R) dI/dt(I) = dR/dt(18V/R) dI/dt = dR/dt*(-18/R**2) dI/dt = .3*(-18/4**2) dI/dt = -.3375amp/s Hope you understand my work! Cheerz
