<h2>The required "option is b) hydrogen bonds must be broken to raise its temperature.</h2>

Explanation:

  • Water has high specific heat due to hydrogen bonds present in it.
  • The Ionisation of water does not affect the specific heat of the water.
  • On decreasing the temperature, there is the formation of bonds hence option (d) is wrong.
  • On increasing the temperature, there is the breaking of bonds hence option (b) is correct.

konstantin123 [22]

Answer:

The percent yield is 70.486%

Explanation:

3CuSO_{4}+2Al\longrightarrow Al_{2}(SO_{4})_{3}+3Cu\\\\Weight\:of\:Al=1.87g\\54g\:of\:Al\:will\:give\:190.5g\:of\:Cu\\

1.87g\:of\:Al\:gives=\frac{190.5\times1.87}{54}=6.597g\:of\:Cu\\ \\Weight\:of\:Cu\:obtained=4.65g\\Theoretical\:Yield=6.597g\\Experimental\:Yield=4.65g\\Percent\:Yield=\frac{Experimental\:Yield}{Theoretical\:Yield}\times100=\frac{4.65}{6.597}\times100=70.486\%

Hence, the percent yield is 70.486%

During a phase change, the temperature of a substance _____.
adell [148]

Answer: remains constant.


Justification:


1) The phase changes are:


i) Boiling: pass from liquid to gas (absorbs heat energy)

ii) Condensation: pass from gas to liquid (release heat energy)

iii) Melting: pass from solid to liquid (absorb heat energy)

iv) Freezing: pass from liquid to solid (release heat energy)

v) Sublimation: pass from solid to gas (absorbs heat energy)

vii) Deposition: pass from gas to solid (release heat energy)


2) When a phase change occurs, whichever it is, the heat energy related with the process, either absortion or release, is used, to overcome the intermolecular forces (in the case of heat energy absortion) or to create stronger intermolecular forces (in the case of heat energy release).


Because of that, the heat energy exchange does not change the temperature of the substance.
