The solution would be like this for this specific problem:
For freezing point
Tf, soln= -114.6-(i*Kf*m)
Tf, soln= -114.6 - (1*1.99*0.40)
Tf= -115.4 C
For boiling point:
Tb=78.4+(i*Kf*m)
Tb=78.4+(1*1.99*.40)
Tb= 79.2 C
So the boiling and freezing point of a 0.40m solution of sucrose in ethanol is 79.2 C and -115.4 C respectively.
The mitochondria is full of energy. It’s primary function is to generate large quantities of ATP.
Hello!
<span>A chemical that will ignite spontaneously in air at a temperature of 130 degree fahrenheit (54.4 degree celsius) or below is identified by the term pyrophoric.
Pyrophoric substances are those that ignite spontaneously when in contact with air at 130 °F or below. Some substances that are pyrophoric include Iron Sulfur (FeS) or some metals like finely powdered Uranium. To handle pyrophoric substances, it is required to work in an inert atmosphere (i.e. an atmosphere without oxygen).
Have a nice day!</span>
Answer:
Hydrogen peroxide should be stored in
1) a cool environment
2) with amber bottles away from sunlight
3) with little drops of sodium phosphate
Explanation:
It has been confirmed that heat and light aids in the decomposition of hydrogen peroxide according to the equation; 2H2O2→2 H2O + O2.
This means that hydrogen peroxide must be stored in a cool place. This will reduce its rate of decomposition. Secondly, it should be stored in amber bottles away from light since light also aids in its decomposition.
Thirdly, drops of sodium phosphate may be added to prevent its catalytic decomposition during storage.
If the graph has no trend which means almost constant, it indicates that the dependent variables will not change when the independent variables change.
