Chemistry
1 answer:
Nonamiya [84]3 years ago
5 0

Answer:

The atoms in the cup of coffee have more energy.

Explanation:

The difference between the hot cup of coffee and the piece of ice is their temperature. The hot cup of coffee has a higher temperature than the ice.

The relationship between the energy and temperature is a direct relationship. This means that higher temperature means higher kinetic energy and vice versa.

Since the hot cup of coffee has  a higher temperature, it means it also have the highest amount of energy. The correct option is;

The atoms in the cup of coffee have more energy.

A solution of KMnO4 has an absorbance of 0.539 when measured in the colorimeter. Determine the concentration of the KMnO4 given
loris [4]

Answer:

Concentration of unknown solution is 0.0416 M

Explanation:

As we know  

Absorbance is equal to the product of molar absorptivity of KMnO4 m, path length and concentration

From the given set of graphical data, it is clear that the absorbance vs concentration is a straight line.  

From the graph, we can obtain-  

Y = 5.73 X – 0.0065

Absorbance = 0.232

0.232 = 5.73 X – 0.0065

X = 0.0416  

Concentration of unknown solution is 0.0416 M
