Answer:
Brown dwarfs are objects which are too large to be called planets and too small to be stars. They have masses that range between twice the mass of Jupiter and the lower mass limit for nuclear reactions (0.08 times the mass of our sun). ... Brown dwarfs are very dim and cool compared with stars.
Explanation:
Human, mold and bacteria are related because they are all organisms.

S. pyogenes causes Strep throat, Varicella zoster causes varicella, Papillomavirus causes HPV, E. faecium cause urinary tract infection B. burgdorferi causes Lyme disease and B. pertussis causes Pertussis.
<h3>What is Bordetella pertussis?</h3>
Bordetella pertussis is a bacteria from the genus Bordetella that causes a respiratory disease known as Pertussis.
Moreover, Bordetella burgdorferi is another bacteria from genus Bordetella that causes Lyme disease, an illness whose symptoms include fever and fatigue.
In conclusion, Streptococcus pyogenes causes Strep throat, Varicella zoster causes varicella, Papillomavirus causes HPV, Enterococcus faecium cause urinary tract infection Borrelia burgdorferi causes Lyme disease and Bordetella pertussis causes Pertussis.

1 mol 2 mol
84g of N2(g) = 84/28 = 3 mol of N2(g)
From the above reaction 1 mol of N2(g) gives 2 mol 0f NH3(g). So 3 mol of N2(g) should give 6 mol or (6x17) 102 g of NH3(g). But we are getting only 85.0 g of NH3.
Hence %yield of NH3 = 100x85.0/102 = 83.3%
Answer D. is correct.
2. 2HgO (s) --------------------- 2Hg (l) + O2 (g)
2 mol 2 mol 1 mol
4 mol 4 mol 2 mol
As only 1.5 mol of O2 is obtained, so % yield = 1.5x100/2 = 75.0%
Moreover 603 g of Hg = 603/200.59 = 3.00 molof Hg. Considering this also
% yield = 3x100/4 = 75%
