Calculate a sm for the equation below. (Round to the nearest whole number.) 4NH, (g) +50, (g) → 4NO(g) + 6H2O(g) = 192.8 J/mol K SH = 205.0 J/mol K S. SHO = 188.83 J/mol K So = 210.8 J/mol K AS JIK

answer;

18.5 seconds

explanation;

velocity is distance covered per unit time; it is given by displacement divided by time.

thus; time = displacement/velocity

total time = total displacement/velocity

total distance = 5000 meters south

total time = 5000/4.5

                  = 1111.11 seconds

but; 1 minute = 60 sec

thus; 1111.11 /60

                = 18.51 seconds

thus; the time taken is 18.5 seconds
