Answer is C
A synthesis reaction looks like this:
A+ B → AB
Answer:
Heat change = 3.77kJ
Explanation:
T1 = 25°C
Mass = 65g
T2 = 30°C
specific heat capacity of water = 4.184J/g°C
Heat energy = ?
Heat energy = MC∇T
Heat energy (Q) = MC(T2 - T1)
Q = 65 * 4.184 * (30 - 15)
Q = 251.04 * 15
Q = 3765.6J
Q = 3.77KJ
The heat change during the reaction was 3.77kJ

Thank you for posting your question here at brainly. The <span>mole fraction of co if the h2 mole fraction is 0.22 and the o2 mole fraction is 0.58 is 0.20, below is the solution:
</span>
mole fraction CO + mole fraction H2 + mole fraction O2 = 1
mole fraction CO = 1 - ( 0.22 + 0.58)=0.20
