Question 0

Combustion apparatus

Answer 0

• Chamber 1: Organic molecule
• Chamber 2: Mg(ClO3)2, which absorbs water
• Chamber 3: NaOH, which absorbs CO2

Question 1

Mole

Answer 1

Avogadro’s number= 6x10^23 molecules of atom

Question 2

Molarity and volume

Answer 2

M1V1=M2V2

Question 3

Ideal Gas Law

Answer 3

pV=nRT

p=1 (N/m^2)= 1 pascal= 1x10^-5 bars
R= 8.314 Nm/Kmol
T= 273 + C

Answer 5

V=T

Question 6

Avogadro’s Law

Answer 6

V=n

Question 7

Gas Law Proportions

Answer 7

(p1V1)/(n1T1)=(p2V2)/(n2T2)
