Question

Calculate how much energy must be transferred as heat in each of the
following situations. Use the following equation:
energy = (specific heat) x mass x (temperature change)
a. A 100 kg tank of water is warmed from 10°C to 25°C;
specific heat = 4,180 J/kg • K

b. 100 kg of steam is raised from 120°C to 135°C; specific heat = 1,870 J/kg • K

Answer 1

Answer:

The acidity of a carboxylic acid is higher than alcohols and even phenols. As discussed above, carboxylate ion, the conjugate base of a carboxylic acid is stabilized by two equivalent resonance structures in which the negative charge is effectively delocalized between two more electronegative oxygen atoms
