Answer:
Reduction potential (Eo) is defined as a tendency of a chemical species to be reduced by gaining an electron and is defined with electrochemical reference of hydrogen, which is globally given the reduction potential of zero [24].
Explanation:
Answer:
3.62×10³ L/mol
Explanation:
Beer-Lambert law relates the absorbance of a sample and its concentration. Its formula is:
A = ε×C×l
<em>Where A is absorbance of the sample, ε is molar absorptivity (A constant f each sample), C its concentration and l is path length</em>
<em />
Now, the formula obtained was:
y = (3.62×10³ L/mol) x
<em>Where Y ia absorbance = A, x its concentration = C and 1cm is path length.</em>
You can write:
A = (3.62×10³ L/mol)×C×l
That means, molar absorptivity of your sample under the meaured conditions is:
<h3> 3.62×10³ L/mol</h3>

a thin solid glass rod that is used in chemistry to combine substances. A stirring rod often has rounded ends and is about the length of a long straw.
<h3>What use serves the stirring rod?</h3>
A crucial component of lab apparatus for mixing chemicals and liquids for reactions is a long, thin stirring rod. Stirring rods are made of solid plastic, glass, or steel and are non-abrasive, chemically inert, and chemically resistant.
<h3>What is the name of the glass stirring rod?</h3>
Glass rod, also known as a stirring rod, stir rod, or solid glass rod, is frequently made of quartz and borosilicate glass. Its diameter and length can be modified to meet your needs.
<h3>Does filtration employ stirring rods?</h3>
When the liquid transfer procedure is paused, use a stirring rod to direct the liquid flow into the funnel and stop small amounts of liquid from dribbling down the beaker's outside.

1) Use a magnet to remove iron fillings. (Mix of salt and gravel left.)
2)Add water to the mixture of salt and gravel. Salt will dissolve in water.
3) Filtrate gravel. (Salted solution is left.)
4) Evaporate water, and salt will be left.
Ok, so 1 pound is equal to 0.453 kg. For a child weight of 42.7 then that makes 42.7 times 0.453, giving you 19.3431 kg. the density of the suspension is equal to 60 mg/mL.
Remember Volume=Mass/Density and the mass is 19.3431 kg which is equal to 19343.1 mg.
(19343.1mg)/(60mg/mL) equals 322.385 mL
I hoped this helped.
