Answer:
- 618.8 J.
Explanation:
- To solve this problem, we can use the relation:
<em>Q = m.c.ΔT,</em>
where, Q is the amount of heat released by steam (Q = ??? J).
m is the mass of the steam (m = 15.5 g).
c is the specific heat of the steam (c of steam = 1.996 J/g.°C).
ΔT is the difference between the initial and final temperature (ΔT = final T - initial T = 100.0°C - 120.0°C = - 20.0°C).
<em>∴ Q = m.c.ΔT</em> = (15.5 g)(1.996 J/g.°C)(- 20.0°C) =<em> - 618.8 J.</em>
The correct answer is A. Photosynthesis is an exothermic reaction. The reaction releases energy. For the second question, the correct answer is A. Atomic theory is subject to change if new information is discovered. Lastly, the correct answer for the third question is option A. <span>Two nonmetals from Group 16 are likely to form a metallic bond.</span>
Is this a test or something else?
