Answer : What is the effect of time and temperature on dissolution of different size of antacid tablets?
Explanation : According to the experiment performed as given in the question; first part deals with the temperature and time of reaction study of the antacid tablet.
In the second part, the size is altered and it reaction time is studied.
In complete experiment three factors are majorly focused i.e. time, temperature and size.
Based on this, one can frame many scientific questions, one example is given below;
Question : What is the effect of time and temperature on dissolution of different size of antacid tablets?
First, the acceleration is solved by dividing the velocity by time.
acceleration = 4 m/s / (1x10^-3s) = 4000 m/s²
Then, we solve for the force by multiplying the mass by acceleration.
F = m x a
Substituting the known values,
F = (12.3 mg)(4000 m/s²) = (12.3 x 10^-6 kg)(4000 m/s²)
F = 0.0492 N
Thus, the force of the froghopper is approximately equal to 0.0492 N.
Answer:
The electronic configuration of Fe2+ is 1s2 2s2 2p6 3s2 3p6 3d6 and Fe3+ is 1s2 2s2 2p6 3s2 3p6 3d5. Fe2+ contains 2 fewer electrons compared to the electronic configuration of Fe.
Answer:
0.103 m/s to the south
Explanation:
The total momentum of the launcher+ball system must be conserved before and after the launch, so we can write:
where
is the total initial momentum (before the launch)
is the mass of the launcher
is the velocity of the launcher after the launch
is the mass of the ball
is the velocity of the ball after the launch (we take the north direction as positive)
Solving for , we find
and the negative sign means that the direction is south.
