How does the spectrophotometer measure absorbance? Why does the dye absorb light (electron transitions)? What color light does B

lue #1 dye absorb? What is the lambda max of the dye? What is Beer's law and how can it be used to calculate the desired concentrations for your solutions? Considering Beer's law, is it possible to look up the molar absorptivity coefficient of Blue #1 dye? How will you estimate what concentrations of dye will be required for an absorbance of 1.0 AU given a path length of 1.46cm? How would you dilute a 2.0 mM dye solution to make 100mL of this 1.0 AU solution? How can the 1.0 AU solution be diluted to form a point on the calibration curve at 0.25 AU?

Why does water have a lopsided shape and act like a chemical magnet?
leva [86]

Answer:

See below  

Step-by-step explanation:

(a) Shape

The formula for water is H-O-H.

The central O atom has four electron pairs around it. They try to get as far from each other as possible, so they point toward the corners of a tetrahedron.

Only two of the pairs have a hydrogen atom attached, so water has a bent shape. The H-O-H bond angle is about 104°.

(b) Chemical magnet

The O atom has a greater attraction than H for the shared electrons in the O-H bonds, so the electrons spend more time near the O.

This gives the O atom a partial negative charge (pink in the diagram) and the H atoms a partial positive charge (blue).

The water molecule acts like a chemical magnet because its negative end attracts the positive ends of other molecules, while its positive ends attract the negative ends of other molecules.

Which of the following best accounts for the difference in mutagenic activity between PAHs and PAHs plus liver preparation?
guapka [62]

Answer: C

Explanation:

Some poly nuclear aromatic hydrocarbons are not carcinogenic in themselves. However, when these are made to interact with living cells, enzymes in the cells could convert the polynuclear aromatic hydrocarbon into a carcinogenic material such as benzo-[a]-pyrene. This can now interact adversely with the deoxyribonucleic acid of living cells leading to genetic mutation, that is, irreversible changes in the genes of organisms.

A sample of seawater contains 1.3g of calcium ions in 3,100kg of solution. what is the calcium ion concentration of this solutio
MakcuM [25]
Unit ppm stands for parts per million. in terms of mass, ppm is equivalent to mg/kg.
since 1 kg is 10⁻⁶ mg, 1 kg is equivalent to million mg.
therefore mg/kg is also ppm.
there are 1.3 g of Ca ions in 3100 kg
if 3100 kg contains - 1.3 g of Ca
then 1 kg contains - 1.3 g / 3100 kg
then Ca ions - 0.42 x 10⁻³ g/kg
Ca ion concentration - 0.42 mg/kg 
therefore Ca ion concentration is 0.42 ppm
