Methyl isocyanate, H3C-N=C=O, is an intermediate in the manufacture of many pesticides. In 1984 a leak from a manufacturing plant resulted in the death of more than 2000 people in Bhopal, India. What are the hybridizations of the N atom, the two C atoms and the O atom in methyl isocyanate? Explain your reasoning. Include the Lewis Structure in your explanation.

Lets say I have a second order ODE: mx''+kx+bx'=kz+bz' ( an EOM where m=3000, b=2000, k=50000, and finally z=.01sin(3.5t)).
In Matlab, how would I use the Matlab command ode23 to solve this ode assuming zero initial conditions, range :0-20 seconds.

An oven has the following specifications: heat capacity = 2000 J/◦C , thermal resistance =0.15 ◦C/watt, ambient temperature=20 ◦C, and desired temperature=300 ◦C.
a) How long will it take the oven to reach 290 ◦C, without feedback?
b) If feedback control is used, what value of K is
required to reduce that time to 1 minute?

You make deposits at the end of each month into an account earning interest at a rate of 6%/year compounded monthly. Your deposits will be $2000/month in the first year, $2200/month in the second year, $2420/month in the third year, $2662 in the fourth year, and so on. How much will be in your account at the end of 40 years? No Excel answers please.
