Answer:
It can be removed by acidic chemicals
Explanation:
Answer:
Magnet
Durability and heaviness.(texture)
Explanation:
Magnet can be use to separate Aluminum from mixture of steel and aluminum.
Though aluminum and steel look alike but magnet can be use to separate it.
If the can attract the magnet or magnet stick to the can, it is a steel can. Aluminum does not stick to magnet.
A mixture of Aluminum and tin can also be separated by magnet.
Tin attract magnet but tin is more durable, heavy and does not corrode easily.
When u touch the three cans, tin is heavy and durable.
The weight in grams = 7.93 g
Given volume = 2.00 
Given density = 0.242 g/
We need to find the Mass(weight) in grams.
To find the weight in grams we need to keep in mind that the volume and density must use the same volume unit for cancellation. So that the volume units will cancel out, leaving only the mass units.
The unit of given volume is 
and unit of volume in density is , so first we need to change the unit of volume from 
to so that the volume units will cancel out, leaving only the mass units.
1 = 16.39 (given conversion)
units get cancel out leaving the unit.
Mass = Density X Volume.
Density = 0.242 g/ and Volume = 32.78
Mass = 7.93 grams (g)
Answer:
Molar concentration of the Fe³⁺ in the unknown solution is 8.01x10⁻⁵M.
Explanation:
When you make a calibration curve in a spectrophotographic analysis you are applying the Lambert-Beer law that states the concentration of a compound is directely proportional to its absorbance:
A = E*l*C
<em>Where A is absorbance, E is molar absorption coefficient, l is optical path length and C is molar concentration</em>
<em />
Using the equation of the line you obtain:
y = 4541.6X + 0.0461
<em>Where Y is absorbance and X is concentration -We will assume concentration is given in molarity-</em>
As absorbance of the unknown is 0.410:
0.410 = 4541.6X + 0.0461
X = 8.01x10⁻⁵M
<h3>Molar concentration of the Fe³⁺ in the unknown solution is 8.01x10⁻⁵M.</h3>
