Hvap, Tvap, Mr are constants
Hvap = 443.38 kJ/kg = 196417.34 J/mol
Tvap = -85.1 °C
Mr = 36.5 g/mol
n = 1.80 mol
ΔS = n*Hvap/Tvap
ΔS = 1.80 * 196417.34 / (273-85.1)
ΔS = 1881.59 J/K = 1.882 kJ/K
For the data set 1, 1, 2, 5, 6, 6, 9 the median is 5. For the data set 1, 1, 2, 6, 6, 9 the median is 4.
hope it helps you
The question is incomplete. The complete question is:
In an experiment similar to the one described in this procedure, a saturated solution of Mg(OH)2 was titrated with 0.0500 M HCI solution. The equivalence point was reached when 0.330 mL of the acid had been added to 50.00 mL of the saturated Mg(OH)2 1. How many moles of H+ were added? How many moles of OH were present in the initial solution of magnesium hydroxide? 2. What are the concentrations of OH and Mg2 in the original 50.00 mL solution? 3 Write the equation for dissolving Mg(OH)2 in water 4. Write the corresponding Ksp expression. 5. What is the value of Ksp found from the experimental data above?
Answer:
Ksp=5.4×10-8
Explanation:
We must find find the concentration of base from the information provided. Then we can now find the concentration of hydrogen ions in the acid, concentration of magnesium ions and hydroxide ions in the base and finally the solubility product of the magnesium hydroxide solution as required. See image attached for more details of the solution to the problem.
Energy transformations are the processes by which one form of energy is converted to another form.
<h3>What are energy transformations?</h3>
Energy transformations refers to the various ways in which different forms of energy are interconverted.
The given energy transformations are as follows:
- Microwaving popcorn: electromagnetic energy to thermal energy
- Water flowing over a waterfall: potential energy to kinetic energy
- Eating an apple: chemical energy to mechanical energy
- Using an iron: electrical energy to heat energy
- Turning on a car: chemical energy to mechanical energy
- Using a flashlight: chemical energy to light energy
- Fireworks on the 4th of July: chemical energy to light energy
- Turning on the light: electrical energy to light energy
- Playing the drum: mechanical energy to sound energy
- Eating a snack before a run: chemical energy to potential energy
- Making toast in the toaster: electrical energy to heat energy
- Turning on a car radio: electrical energy to sound
- The Sun: nuclear energy to light
- Plant photosynthesis: Light energy tp chemical energy
Therefore, energy transformations are the processes by which one form of energy is converted to another form.
