Hydrogen bonding occurs between a hydrogen atom and an electronegative atom (e.g., oxygen, fluorine, chlorine). The bond is weaker than an ionic bond or a covalent bond, but stronger than van der Waals forces (5 to 30 kJ/mol). A hydrogen bond is classified as a type of weak chemical bond.
chemical potential energy, thermal energy, electrical energy, sound energy
Explanation:
the coal is chemical potential energy because it is just sitting there, the coal fueled power plant is thermal energy because it is using the heat from the coal to work the power plant, that is then turned into electrical energy, which then goes to the radio which displays sound energy

Answer:
<em>H.vap = 6.544 kJ/mol</em>
Explanation:
Clausius-Clapeyron Equation
<em>In P = H.vap / RT</em> where T = 20 + 273 = 293K
H.vap = In P (RT) = In 11 (8.314 x 293) = 6543.861 J/mol = 6.544 kJ/mol
It’s the 3d one
Good luckkkkkkkk
Sunlight is a renewable perpetual resource, while oil is a nonrenewable
resource.
