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?

CaHeK987 [17]

Answer:

Sometimes it is not an increase in force that is desired, but an increase in  

distance or speed.  Take a baseball bat as an example.  A bat is a class 3  

lever, meaning the effort is in the middle.  This means that it has a  

mechanical advantage of less than one.  However, when the bat is swung,  

the end of the bat is travelling at a much higher speed than the location at  

which the batter is holding it.  This allows the ball to leave the bat at a  

much higher speed than it would with a class one or two lever.

12.5 mL of 6.0 M KCl is diluted to make a 1.5 L solution. The molarity of the dilution solution is ___ M. (Round atomic masses t
horsena [70]

The molarity of the dilution solution is 0.050 M

<h3>Further explanation</h3>

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

Dilution formula :

\tt M_1.V_1=M_2.V_2

M₁=6 M

V₁=12.5 ml

V₂=1.5 L=1500 ml

\tt 6\times 12.5=M_2\times 1500\\\\M_2=\dfrac{6\times 12.5}{1500}=0.05~M\\\\for~sig.fig\rightarrow 0.050~M

When you boil water, why does the level of liquid decrease?
Ganezh [65]

Answer:

when you boil water, you convert it into water vapor, which leaves the pot and mixes with the atmosphere. If you boil the pot long enough, eventually all the water in it is converted to vapor and leaves. the pot is then empty.
