In order to compute the y-component of a vector, we simply use the formula:
Fy = F*sin(∅)
Where ∅ is the angle of the vector measured from the positive x-axis and F is the magnitude of the vector.
Similarly, the x-component is calculated by substituting sin(∅) with cos(∅)
Explanation:
First, we will calculate the number of moles of HF as follows.
No. of moles of HF = volume × concentration of HF
=
= 1.78 mol
According to Henderson-Hasselbalch equation,
pH =
=
Since, no change in the volume is taking place. Hence, putting the given values into the above formula as follows.
pH =
= 0.208
= 1.614
moles of NaF = 2.87 mol
Thus, we can conclude that moles of solid NaF present are 2.87 mol.
Answer:
14 neutrons
Explanation:
Mass - Atomic Number = Neutrons
Answer:
only the wave energy of the water moves
Explanation:
The plan will not work due to the fact that only the wave energy of the water moves and not the water itself.
<em>The wave motion of water does not displace the water. It is only able to transfer energy from one point to another within the medium. Hence, the ball will hardly be displaced because the water itself does not move. However, it can get to the shore with the assistance of the water current.</em>
