Hello,
I've oxidated lead using electrolysis. I think it should be lead (iv) oxide ( I use 10 V power source and the color of the product is like color of Fe2O3). now I want to make lead (ii,iv) of it.
I've tryed heating it in a plate but it doesn't work. what should I do?
The electric field has a magnitude of 3.0 N/C at a distance of 60 cm from a point charge..What is the charge?
The tension in a string holding a solid block below the surface of a liquid (of density
greater than the block) is T0 when the container is at rest. When the container is given an upward acceleration of 0.250g, what multiple of T0 gives the tension in the string?

The first order rate of constant for the decomposition of a certain insecticide in water at 12degrees is 1.45/yr. A quantity of this is washed into the pond leading to a concentration of 5.0*10^-7M.calculate the halflife.
Samples of size 25 are selected from a population with a mean of 40 and a standard deviation of 7.5. What is the mean of the sampling distribution of sample means?
of 10 genes studied in yeast, 7 are found to form a network of metabolic interactions. If this set of 7 genes was chosen arbitrarily from the 10 that were studied, how many different sets would be possible? Show your calculation and the reasoning.a
Human colour vision is “produced” by the nervous system based on how three different cone receptors interact with photons of light in the eye. These three different types of cones interact with photons of different frequency light, as indicated in the following chart:
Cone Type Range of Light Frequency Detected
S 6.00-7.49 x 1014 s-1
M 4.76-6.62 x 1014 s-1
L 4.28-6.00 x 1014 s-1
What wavelength ranges (and corresponding colours) do the three types of cones
detect?
- Define the Glomerular filtration rate (GFR) and state what are normal values
- What are the important factors that determine GFR?
- Define alkalosis, pH and carbon dioxide and bicarbonate values
- Use the Davenport diagram to explain alkalotic disorders and give examples of the primary disorders- metabolic and respiratory
