Answer: The amount of heat energy in joules required to raise the temperature is 526 Joules
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed = ?
m= mass of substance = 7.40 g
c = specific heat capacity =
Initial temperature of the water = = 29.0°C
Final temperature of the water = = 46.0°C
Change in temperature ,
Putting in the values, we get:
The amount of heat energy in joules required to raise the temperature is 526 Joules
Answer: 0.45 moles of will be produced from 0.15 moles of propanol.
Explanation:
The balanced chemical reaction is:
is the limiting reagent as it limits the formation of product and
is the excess reagent.
According to stoichiometry :
2 moles of produces = 6 moles of
Thus 0.15 moles of will produce=
of
Thus 0.45 moles of will be produced from 0.15 moles of propanol.
