What if when I find my product, I get the same compound as I did in my
reactant? For example, FeCl3 + HCl ->FeCl3 + HCl. Then something is
wrong. In this case, FeCl3 and HCl usually don't react. In very
concentrated solutions of HCl, the FeCl4^- or FeCl6^-3 ion can form.

Answer:
The average speed of a car is 20 km/h.
Explanation:
We have,
Distance covered by car is 10 km
Time taken by the car to cover that distance is 30 min. 30 min means 0.5 hours.
It is required to find the average speed of a car. It can be calculated using formula of average speed which is given by :
So, the average speed of a car is 20 km/h.
Answer:
Amplitude
Explanation:
The lower the amplitude, the lower the frequency.
Answer:
2*10^9electrons
Explanation:
Remember that the net force will be zero at terminal voltege so
Mg = 6πrng
At 35v
We have
qvr = 6πrng
q= 6 x 3.142* nx 2.6*10^-5/35
q,= 3.2x 10^ - 10C
So using n= q/e
= 3.2x 10^ - 10C/1.6*10-19
= 2*10^9electrons
