Question
Which molecule Shown Below has MORE Molecular Attraction due to Hydrogen bonding between other molecules of itself? H_2O CH_4 C_6 H_14 (straight chain) Given the general chemical equation which is in Equilibrium shown below: A + B lrarr C + D If the concentration of "B" is Increased. What will happen to the Equilibrium? _____________ (To Avoid confusion answer with the NUMBER of the correct answer below.) The Reaction will shift to the Right {Products} The Reaction will NOT Shift The Reaction will shift to the Left {Reactants} Calculate the energy need to melt 150. grams of ice. Answer = __________ calories
Explanation / Answer
H2O has more molecular attraction due to Hydrogen bonding between other molecules of itself
Answer is
A) H2O
if concentration of B is increased reaction will shift towards to the right (products)
1) shift to the right (products)
Mass = 150 g
enthalpy of fusion of ice = 333.55 J/g
Energy = masss * enthalpy = 150 g * 333.55 J/g = 50032.5 J = 11.96 cal Answer
