Answer:
=> 0.10 moles
Explanation:
The question is asking us to find the moles of NaCl cid formed.
We have been provided with;
0.10 L of 1.0 M NaOH.
We know that mole ratio of the reaction is 1:1 and also the molarity of a solution is contained in 1 L or 1000 mL or 1000 cm³.
This means that;
1.0 M is contained in 1.0 L.
X mol is contained in 0.10 L
= 0.10 moles of NaCl formed
Answer: The energy of combustion of butter is 31.5 kJ/g
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 by calorimeter =?
C = heat capacity of calorimeter =
Initial temperature of the calorimeter = =
Final temperature of the calorimeter = =
Change in temperature ,
Putting in the values, we get:
As heat absorbed by calorimeter is equal to heat released by combustion of butter
Heat released by 0.22 g of butter = 6.94 kJ
Heat released by 1g of butter =
The energy of combustion of butter is 31.5 kJ/g
