In order for a high temperature boiler or steam engine to produce superheated water, or steam: the heat source must be greater t
Vinil7 [7]

Answer:

the heat source must be greater than 100°C

the water must be permitted to evaporate quickly

the system must be sealed and become pressurized above atmospheric pressure

the vapor pressure must be kept below 760 mmHg

Explanation:

A superheated water is a dry form of steam in which hydrogen bonds that strongly binds the molecules of water has been overcome.

Superheated water finds application in a wide range of places. For example they are used for sterilization of clinical equipment.

  • To produce steam or superheated water, the temperature of the source must be greater than the boiling temperature and less than the critical temperature at 374°C.
  • Since superheated water is steam and steam is water in gaseous form. The water must be made to evaporate more quickly than it should condense back.
  • High pressure and sealing the system helps to produce superheated water very fast.
  • If the pressure between the vapor is kept low, water will boil faster.

The normal boiling point of ethanol (c2h5oh) is 78.3 °c and its molar enthalpy of vaporization is 38.56 kj/mol. what is the chan
kaheart [24]
When the entropy change of vaporization
       
 = enthalpy of vaporization/boiling point temperature 

when we have the enthalpy of vaporization = 38560 J/mol

and the boiling point temperature in Kelvin = 78.3 + 273 = 351.3 K

by substitution:

∴the entropy change of vaporization = 38560J/mol/351.3K

                                                               = 109.76 J/K/mol

and when the liquid has lesser entropy than the gas and we here convert from

gas to liquid so, the change in entropy = -109.76 J/K/mol

now, we need the moles of C2H5OH = mass/molar mass when the molar

mass of C2H5OH = 46 g/mol and mass = 42.2 g 

∴ moles of C2H5OH = 42.2 g / 46 g/mol = 0.92 moles

when 1 mol of C2H5OH turns in liquid entropy change →-109.76 J/K/mol

∴ 0.92 mol of C2H5OH → X

∴ X entropy change when 0.92 mol = -109.76 *0.92 mol / 1 mol

                                                             = 84.64 J/K

20 Points! (2) Which of the following statements are true about a strong base and a weak base at a pH of 11?
marshall27 [118]
The answer to this question is that <span>the strong base will require less HCl to bring the pH to 7 than the weak base. The string base ionizes completely so the [OH-] will be neutralized faster. The weak base has an equilibrium that will constantly shift</span> to compensate for any [OH-] loss, meaning more HCl will be needed to titrate it to lower pH.

Is electrolysis of water an example of a chemical reaction? Why or why not?
katen-ka-za [31]
Chemical reaction is any process that involves rearangent of the molecular or ionic structure of substances. each chemical reaction is characterised by an activation energy required for the reaction to occur ,for the change or rearrangement to take place
now fro combustion of fuel:we provide this energy by spark (heat pulse).now what about electrolysis?just the mode and manner of providing energy is different:instead of talking of activation energy,we talk of activation overpotential,both bring conceptually the same thing.heat energy is replaced by potential difference in rough terms.

so in short ,electrolysis is a chemical change ,just the mode of activation is different that thermally initiated chemical reactions
