Determine how much energy is needed to change 50 g of liquid water at 100°C to steam.
marin [14]

Answer:

Q=113,000J

Explanation:

Hello there!

In this case, since the vaporization process is carried out in order to turn a liquid into a gas due to the addition of heat, we can use the following heat equation involving the heat of vaporization of water or any other substance:

Q=m*\Delta _{vap}H

Thus, since this heat of vaporization for water is 2259.36 J/g, we plug in this amount to obtain the total energy for this process.

Q=50*2259.36 J/g\\\\Q=113,000J

Which is positive due to the necessity of heat.

Regards!

What is the percent by mass of nahco3 in a solution containing 10 g of nahco3 dissolved in 400 ml of h2o?
Marat540 [252]
Answer is: the percent by mass of NaHCO₃ is 2,43%.
m(NaHCO₃) = 10 g.
V(H₂O) = 400 ml.
d(H₂O) = 1 g/ml.
m(H₂O) = V(H₂O) · d(H₂O).
m(H₂O) = 400 ml · 1 g/ml.
m(H₂O) = 400 g.
m(solution) = m(H₂O) + m(NaHCO₃).
m(solution) = 400 g + 10 g.
m(solution) = 410 g.
ω(NaHCO₃) = 10 g ÷ 410 g · 100%.
ω(NaHCO₃) = 2,43 %

What is Science-Based Medicine?
SSSSS [86.1K]

Answer: Medicine is a scientific field whose subject of research is the health and well-being of living whips.

Explanation:

Primarily medicine deals with the study of man and the treatment of man, but also of some animal species. Two principles are founded: theoretical research and practical, or often called a clinical policy. The academic and research law will enable a specific area, disease, congenital disability, or condition to be defined, studied in detail, and after the conclusion of tests performed. Concluded medical theory is most often put into a usable form through various educational processes, which will lead to the ultimate goal - to improve the health of living forms on which this theory will be applied.
