40.6 kJ of heat energy had been emitted.
CO(g) + 2H2(g) CH3OH(l)CO volume, V (CO), equals 15 L or 0.015 m3.
Temperature = 85 0C = 85 + 273 = 358 K Pressure = 112 kPa = 112,000 PaPV = nRT n= 112000 0.015 / 8.314 358 n(CO) = 0.56 moles,
according to the ideal gas law.H2 volume is 14.4 L or 0.0144 m3
T = 750C + 273 K = 348 K n(H2) = 99191.84 0.0144 m3 / 8.314 348 K = 0.49 moles of H2 Pressure = 744 torr = 99191.84 Pa
Hydrogen is the limiting reagent, according to the calculation above.CH3OH = H2 = 0.49/2 = 0.245 m-238.6 (-110.5) = -128.1 kJ/mol for H(rxn) = H(f) (CH3OH) - H (rxn)
We must now multiply H(rxn) by the number of moles of methanol.
E = H(rxn) n(CH3OH) = 128.1 0.245 = 40.6 kJ.

Explanation:
Oceans can influence weather and climate. For example, cities located near large water bodies like oceans tend not to have extreme climates
The bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.
Electronegativity refers to the ability of an atom in a compound to attract the electrons of the bond towards itself. It is a periodic trend that increases across the period but decreases down the group.
The electronegativity difference between the two atoms as shown in the question is 1.55. This means that the bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.

The hot water increases the temperature of air in the bottle, which increases the volume of the bottle and the air pressure in the bottle.
NaCl : In case of Sodium chloride Ionic bonding exists, as sodium is a cation and chloride is an anion. So, these two opposite charged species will attract each other and form ionic bond.
HF : In case of Hydrogen fluoride, Hydrogen bond interactions are found this is because when hydrogen is attached to either Oxygen, Nitrogen or Fluorine atom it gets involve in hydrogen bonding interactions with the neighbor oxygen, nitrogen or fluorine atom (highly electronegative).
HCl : In Hydrogen chloride dipole dipole interactions exist. A partial positive hydrogen atoms interacts with a partial negative chlorine atom of neighbor molecule.
F2 : As fluorine molecule is neutral and charge less, so it will interact with another fluorine molecule through London dispersion forces.
