They consider it to be psuedoscience because we no longer need the location of stars and planets to know when to do things like harvest crops.
Hope this helps!
Can u plz mark me as brainliest? I really need it!
Answer:
The correct answer is - a positive feedback loop
Explanation:
Oxytocin is a peptide hormone that is released during labor in women which contracts the uterus and n increase of the oxytocin causes more release of oxytocin hormone to increase the contraction more strongly.
Oxytocin shows a positive feedback loop as its release leads to more of the oxytocin release by stimulates its more release. Most of the hormones show negative feedback release.
<u>Answer</u>: (1 is the oldest event)
1. Europe sent explorer and merchants along the Silk Road and across the Indian Ocean
2. European nations colonized countries in Southeast Asia
3. World War II broke out in Europe as well as in East Asia and Southeast Asia
4. Nations in Southeast Asia demanded and won independence
Multiple nations in Southeast Asia obtained their independence after World War II some as late as 1975 (Portuguese Timor - now East Timor).
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%
