The answer is B. Non-renewable resources are non-renewable because we cannot renew, or make more, of it. Hope this helps!!!
Answer: the person standing up
Explanation:
the person has the potential to fall or move from position
Answer:
![-277.6\ \text{kJ/mol}](https://tex.z-dn.net/?f=-277.6%5C%20%5Ctext%7BkJ%2Fmol%7D)
Explanation:
Heat of combustion of
= -1366.8 kJ/mol
Heat of formation of
= -393.5 kJ/mol
Heat of formation of
= -285.8 kJ/mol
The reaction is
![C_2H_5OH(l)\rightarrow 2CO_2(g)+3H_2O(l)](https://tex.z-dn.net/?f=C_2H_5OH%28l%29%5Crightarrow%202CO_2%28g%29%2B3H_2O%28l%29)
Assuming
is the standard enthalpy of formation of ethanol
![-1366.8=2\times (-393.5)+3\times (-285.8)-x\\\Rightarrow x=2\times (-393.5)+3\times (-285.8)+1366.8\\\Rightarrow x=-277.6\ \text{kJ/mol}](https://tex.z-dn.net/?f=-1366.8%3D2%5Ctimes%20%28-393.5%29%2B3%5Ctimes%20%28-285.8%29-x%5C%5C%5CRightarrow%20x%3D2%5Ctimes%20%28-393.5%29%2B3%5Ctimes%20%28-285.8%29%2B1366.8%5C%5C%5CRightarrow%20x%3D-277.6%5C%20%5Ctext%7BkJ%2Fmol%7D)
The standard enthalpy of formation of ethanol is
.
