From the gas law, PV=nRT we can say that P(pressure), V(volume) and T (temperature) are related to each other. The initial volume of sample is 408 ml
Given that initial volume of the sample = V1
initial pressure of the sample = 0.92atm
initial temperature of the sample = 23.2oC
Final pressure of the sample = 1.3atm
Final temperature of the sample = 40.1 oC
Final volume of the sample = 500ml = 0.5L
Using the relation P1V1/T1 = P2V2/T2
V1 = 1.3x0.5x23.2/40.1x0.92 = 15.08/36.892 = 0.408
Hence the initial volume of sample = 408 ml

Answer:
Butan-1-ol or Butanol
2-methylpropan-2-ol
2-methylpropan-1-ol
Butan-2-ol
Explanation:
Data Give:
Three Isomers are given
names of These =?
Details:
Isomers:
Isomers are those chemical compounds that have same molecular formula but different structures.
In the given question the compound have same molecular formula that is C₄H₉OH but the structures are different.
So due to different structures they are named differently.
The 1st and last one are straight Chains and the other 2 are branched. all the structure have four carbon atoms, one OH group and 9 hydrogen atoms.
Names are given in attachment
butan-1-ol or Butanol
As it contain 4 carbon atoms an -OH group is attached at position 1.
________________
2-methylpropan-2-ol
In this -OH and -CH₃ is attached on carbon 2
_____________
2-methylpropan-1-ol
In this -CH₃ attached at position 2 and -OH is attached on Carbon 1.
______________
Butan-2-ol
In this 4 carbons are in straight chain and a -OH group is attached on position 2 of carbon
The rate of the backward reaction increases
Explanation:
It is evident that if the reaction is left to proceed spontaneously, the forward reaction is favored because it results in a decrease in pressure in the system (The total reactants have 5 moles and the products have 3 in total).
Increasing H₂O concentration is then reaction, therefore, stymies the forward reaction and favors the reserves reaction. This is because the reverse reaction will lead to reduced pressure.
Answer:
- 618.8 J.
Explanation:
- To solve this problem, we can use the relation:
<em>Q = m.c.ΔT,</em>
where, Q is the amount of heat released by steam (Q = ??? J).
m is the mass of the steam (m = 15.5 g).
c is the specific heat of the steam (c of steam = 1.996 J/g.°C).
ΔT is the difference between the initial and final temperature (ΔT = final T - initial T = 100.0°C - 120.0°C = - 20.0°C).
<em>∴ Q = m.c.ΔT</em> = (15.5 g)(1.996 J/g.°C)(- 20.0°C) =<em> - 618.8 J.</em>
