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

It's a chemical change because ethanol is converted into other substances.
Answer:
Explanation:
The first two answers are the correct ones. Sometimes C can be true, but it is not a condition. Some equations produce many more products than reactants and some equations are made from more reactants than products.
The last one is normally not true, but the three equations I choose below do give D to be true. Still it does not happen all the time.
C8H18 + 12.5 O2 ===> 8CO2 + 9H20 This is the combustion equation that drives your engine. The coefficients do not add.
Same number of reactants as products.
CH4 + 2O2 ==> CO2 + 2H2O
More products than reactants.
Cu + 4HNO3 ==> Cu(NO3)2 + 2NO2 + 2H2O
More Reactants than products.
H2 + I2 ==> 2HI
Answer:
Alcohol will form at more substituted carbon due to carbocation rearrangement so 2-hexanol
Explanation:
Well if it’s acid catalyzed
Makes driving less stressful
