need 0.500 x 0.125 = 0.0625 moles of NaOH. The molecular weight is 23+16+1 = 40, so 0.0625 x 40 = 2.5 grams will do the trick.
Answer:
We can see that at the boiling point, both liquid and gas are in equilibrium with one another. This is true for any applied pressure and boiling point temperature combination. As a result, we see liquid-gas equilibrium for every temperature and pressure combination on the graph in Figure 13.6.
Answer:
V₂ = 4.0L
Explanation:
Decreasing temperature => Decreasing Volume (Charles Law)
For a given volume, use a temperature ratio that will give a smaller volume.
Volume at lower temp = 4.6L(70K/82K) = 4.0L ... Using (82K/70K) would give a larger volume => contrary to temperature effects on gas volumes when pressure and mass are kept constant.
Pressure effects on Gas Volumes:
Note: The same idea is applied to pressure effects on gas volumes also except that changes in pressure affect gas volumes indirectly. That is, an increase in pressure => decrease in volume, or a decrease in pressure => increase in volume. Boyles Law => V ∝ 1/P.
Given a gas volume of 4.60L at 760mmHg, what is volume at 848mmHg?
Increasing pressure => Decreases Volume (Boyles Law)
For the given volume use a pressure ratio that will give a smaller volume.
Volume at higher pressure = 4.6L(760mm/848mm) =4.1L. Using (848mm/760mm) would give a larger volume => contrary to pressure effects on gas volume when temperature and mass of gas are kept constant.
A couple moment is produced when a network of forces do not have a resultant force, but only produces moment. As a result, it induces rotation without translation. That means the two forces are equal.
Moment = Force * Distance
In order to determine the vertical force, we must know the distance between the two forces which is represented by the length of the pipe. Suppose the pipe is 0.5 m, then the force is
400 N·m = F*0.5 m
F = 800 N
