When ethane (C2H6) reacts with chlorine (Cl) then the main subject is C2H5Cl but also a small amount of other substances containing Cl such as C2H4Cl2. a) Calculate the theoretical efficiency of C2H5Cl when 125 g
of C2H6 reacts with 255 g of Cl2 if only C2H5Cl and HCl are assumed to be formed.

h let me think

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
