Calculate the Orthoquinone formed (µg/ml) at 30 minutes incubation time? Unknown OD 0.076

Find the equation of the line which passes through the point (9,5) and has slope 1. Give your answer in the form y=m x+b. The constants should be given exactly, e.g., 1/3 rather than 0.33.

A reversible chemical reaction combines A and B to produce C and D. At equilibrium, A, B and C are present in concentrations 1 M, 0.05 M, 500 mM respectively.

If the rate constants are k1=2M^{-2}s^{-1} and k2 = 1 M^{-1} s^{-1}, what is the concentration of D in M at equilibrium? Give the result to three significant figures.

A chemical dye absorbs light with wavelength 578 nm.

Using a standard solution of concentration 0.7 mM, the absorption is measured

to be 0.8 units. The absorption for a solution of unknown concentration is then

measured and found to be 0.6 units. What is the concentration? Give the answer to

at least 3 significant figures.

1) If calcium and phospate ion concentrations are adequate for crustallisation, why desnt it occur throughout the body ?

2) if calcium and phospate ion concentrations are not adequate for crystallisation, why should it occur at all ? and suprisingly at specific locatio.
