The bond energy of each carbon-oxygen bond in carbon dioxide is d. 736 kJ
Since the chemical reaction is 2CO + O₂ → 2CO₂ and the total bond energy of the products carbon dioxide CO₂ is 1,472 kJ.
Since from the chemical reaction, we have 2 moles of CO₂ which gives 1,472 kJ and there are two carbon-oxygen, C-O bonds in CO₂, then
2 × C-O bond = 1,472 kJ
1 C-O bond = 1.472 kJ/2
C-O bond = 736 kJ
So, the bond energy of each carbon-oxygen bond in carbon dioxide is d. 736 kJ

Because I (iodide) is better leaving group than Cl, so it will leave when this molecule is reacted with strong base (sodium tert-butyl oxide) giving the elimination product provided in picture<span />
In this question, you are given the wine/alcohol concentration (12%) and the volume of the alcohol(0.75l). You are asked the alcohol content in milli liters, so don't forget to change the unit. Then the equation would be:
Alcohol content= alcohol concentration * bottle volume
Alcohol content = 12%* 0.75l * 1000ml/l= 90ml
Answer:
Q = 3937.56 J
Explanation:
Heat transferred due to change in temperature is given by :
c is the specific heat of water, c=4.18 J/g-°C
We have, m = 15 g, 
So,
Hence, 3937.56 J of heat is transferred.
