Answer:
shhhh thats wht u did to me beach
Explanation:
A. 12.5 m/s.
The average speed is defined as the relationship between the displacement made by a body and the total time it took to perform it.
The formula that will allow you to calculate the average speed is:
v = d/t, where d is the traveled distance and t the time it took to travel the distance.
We hace to convert 4 minutes to second:
(60 s/1 min)*(4 min) = 240 s
So, the average speed is:
v = 3000 m/240 s
v = 12.5 m/s

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%
