Lelechka [254]

Answer: The temperature of the rainforest does not experience a drastic fall as in the case of the desert.

Explanation:

In the desert the average daytime temperature remains 100°F and that of the rainforest is 85°F. But average monthly temperatures are lower in the case of desert as compared to the rainforest although the vegetation cover is higher in rainforest as compared to desert so humidity is also more. During night in desert temperature drops to an average of 25°F whereas in rainforest during night temperature level does not drop much it drops to only 71°F. Therefore, the average monthly temperature on desert is lower than rainforest.

Nitrogen gas reacts with hydrogen gas to form ammonia What are reactants in this chemical reaction?
krek1111 [17]

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%
