Since the given data is mass in terms of ounces, it would be easier to determine first the mass in terms of pounds. The conversions is 1 oz = 0.0625 pounds. The conversion is as follows:
16.9 oz * 0.0625 lbs/oz = 1.06 lb
The mass of water is 1.06 pound. To determine the volume, we use the density of water which 1 g/mL.
Volume = 1.06 lb * 1000 g/ 2.2 lb * (1 mL/1 g) = 481.82 mL
Answer:
B) the chemicals are gaining energy from the surroundings.
Explanation:
The positive sign of the energy difference in a chemical reaction would indicate that the chemicals are gaining energy from the surroundings. This is what happens in an endothermic reaction.
In an endothermic reaction, heat is absorbed from the surroundings hence the surrounding becomes colder at the end of the changes.
- Here the energy change is assigned a positive value.
- This is because the heat energy level of the final state is higher than that of the initial state.
- So, the difference gives a positive value.

Naproxen is known to be a weak acid. In order to calculate
its ka and pka, use the equation of getting the ph of weak acid which is ph=
-1/2 log [(Ka)(Mwa)]. The Ka value is 3.18x10^-5. The pKa can be obtained
through pKa = - log Ka. The pKa is 4.5.
