It would be:
B. HCl
A metal will react with an acid to form a salt (MgCl2) and H2.
Answer:
Initial Speed ____4m/s. Final Speed ______6m/s. Time ______5 seconds . Acceleration =________0.4m/s²
Explanation:
The acceleration is the rate of change of velocity during time t .
acceleration = Final velocity- Initial velocity/ Time
= Vf- Vi/ t
a = Δv/ Δt
= 6m/s- 4m/s/ 5s
= 2m/s/ 5s
= 0.4m/s²
It can also be defined as the difference of the initial and final velocity ( velocities measured in meters per second) during the given time t measured in seconds .The SI unit of acceleration is meter per second squared.
If the velocities are not measured in meters per second or time is not measured in seconds then the units are changed accordingly.
D =temperature of the water
0.3 M FeCl2, solution two is 1.7 M MgCl2.
