Heptane means seven carbon atoms and since the general formula is CnH2n+2, heptane will be C7H16
Because that is the outer ring.
Answer:
32km/hr
Explanation:
The question asks to calculate the average speed for a boat.
Mathematically, the average speed is the total distance divided by the total time
Let’s get the total distance traveled:
That would be 70km + 26km = 96km
Now the total time taken would be 3 as the boat did not move at all for an hour.
The average speed is thus 96/3 = 32km/hr
D, KOH is a concentrated Base and HCL is an acid. D is the only one that has these two.
