The result of an exothermic reaction is released heat. According the Le Chatelier's principle, increasing<span> the </span>temperature means increasing<span> the amount of products. This means that </span><span> there will be more reactants left at equilibrium.</span>

lisabon 2012 [21]
Answer is: <span>D)194 kJ/mol, exothermic
</span>ΔHreaction = ∑(product bond energies) - ∑(reactant bond energies).
∑(product bond energies) = ΔHreaction + ∑(reactant bond energies).
ΔHreaction must be negative (exothermic) if ∑(product bond energies) is positive.
∑(product bond energies) = -1352 kJ/mol + <span>1546 kJ/mol.
</span>∑(product bond energies) = 194 kJ/mol.
∑ is summation.

How much energy will it take to raise the temperature of 75.0 g of water from 20.0°C to 55.0°C?
Hatshy [7]

Answer:

We can use heat = mcΔT to determine the amount of heat, but first we need to determine ΔT. Because the final temperature of the water is 55°C and the initial temperature is 20.0°C, ΔT is as follows:

ΔT = Tfinal − Tinitial = 55.0°C − 20.0°C = 35.0°C

given the specific heat of water as 1 cal/g·°C. Substitute the known values into heat = mcΔT and solve for amount of heat:

=  heat=(75.0 g)(1 cal/ g· °C )(35.0°C) =

= 75x1x35=2625 cal
