23. Enzyme A, as the temperature increases, the rate of reaction goes down. However, Enzyme B as the temperature goes up the reaction goes up.
24. Enzyme B is more active in a human cell, the reaction is what you want and everytime the temperature goes up in enzyme B the reaction goes up.
Solids' particles move a lot faster and closer together. Liquids' are more spread apart and move slower. So there is more energy in the solid

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
Answer: Crocodiles and tigers both have four legs
