To solve this you need to find the radius of the bigger cylinder so you have to solve the equation 36π=
π(9). When you solve it you end up with a radius of 2 in which you multiply by 1.2 which gives you the radius of the new cylinder which is 2.4. With the new radius you simply find the volume of the bigger cylinder which is 51.94π

Answer:</h3>
43.5 mL
<h3>
Explanation:</h3>
We are given;
- Molarity of dilute acetic acid is 1.74 M
- Volume of the solution that needs to be prepared is 200 mL
- Molarity of the stock solution 8 M
We are required to determine the volume of acid that must be used.
- We need to know the dilution formula;
- According to the dilution equation;
M1V1 = M2V2
Rearranging the formula;
V1 = M2V2 ÷ M1
= (1.74 M × 200 mL) ÷ 8 M
= 43.5 mL
Therefore, the volume of the concentrated acid that must be added is 43.5 mL

Hello,
The Rachford-Rice equation should be used in this case:
The distribution coefficients could be approximated via Raoult's law and the Antoine equation for the vapor pressure:
For n-hexane: A=6,9895, B=1216,92 and C=227,451
For n-octane: A=7,14462, B=1498,96 and C=225,874
*Those values and the Antoine law are used in °C and mmHg.
Replacing each value in the Rachford-Rice equation and solving for T, one gets the flash drum temperature as 95.24°C (attached picture), thus, the compositions in both the liquid and the vapor phases are:
Best regards.
Answer:
The reactivity series of metals is a chart listing metals in order of decreasing reactivity. In general, the more reactive a metal is: the more vigorously it reacts with other substances. the more easily it loses electrons to form positive ions (cations)
