CL=2,8,7
C
Answer:
The volume of the liquid should be measured before it is heated.
Explanation:
Answer:
= 2113.44 kJ
Explanation:
When 1 mole of CH4 (g) burns in excess oxygen -714.0 kJ of heat is released.
For 47.50 g;
molar mass of CH4 = 16.042 g/mol
Number of moles of CH4
= 47.5 g /16.042 g/mol
= 2.96 moles
Therefore;
1 mole = -714.0 kJ
Heat change for 2.96 moles
= 2.96 moles × -714.0 kJ
= 2113.44 kJ
