Alenkinab [10]

Answer:

E=1.48x10^4J

Explanation:

Hello!

In this case, since the energy implied in a heating process is computed by using the following equation:

E=mC(T_f-T_i)

Whereas m is the mass, C the specific heat and T the temperature. In such a way, by plugging in the given mass, specific heat and temperatures, we obtain the following energy:

E=187.0g*4.703\frac{J}{g\°C} (52.9\°C-36.1\°C)\\\\E=1.48x10^4J

Considering that the specific heat can by used by unit of °C or K because their difference is equivalent.

Regards!

Which compound is produced when HCl(aq) is neutralized by Ca(OH)2(aq)?
Kisachek [45]
The answer is (1) CaCl2. The reaction formula of this is HCl + Ca(OH)2 = CaCl2 + H2O. This is a reaction of base and acid. So the production is CaCl2 and H2O.

What is a solvent? what is a solute ? which one is usually found in the greater amount?
PSYCHO15rus [73]
A solvent is something that can have something else dissolved within it and turn into a homogenous solution, while the solute is that something else that can be dissolved into the solvent. Usually, the solvent is found in greater amount because most (except for rare cases) solvents have a saturation point that is below the equal-mass point.
