Answer:
950mL
Explanation:
The following were Data were obtained from the question:
Initial volume (V1) = 100mL
Initial pressure (P1) = stp = 760mmHg
Final pressure (P2) = 80mmHg
Final volume (V2) =..?
The final volume of the gas can be obtained by using the Boyle's law equation as follow:
P1V1 = P2V2
760 x 100 = 80 x V2
Divide both side by 80
V2 = (760 x 100) /80
V2 = 950mL
Therefore, the new volume of the gas is 950mL
It would be <span>C21H22N2O2</span>
Answer:
Explanation:
Mass of Erlenmeyer flask + KHP = 84.847 g
Mass of Erlenmeyer flask = 84.347 g
Mass of KHP = .5 g
moles of KHP = .5 / 204.23
= 2.448 x 10⁻³ moles
moles of NaOH reacted = 2.448 x 10⁻³
Final buret reading = 12.25 mL
Initial buret reading = 0.50 mL
Volume of NaOH added=
sand silt and clay but also has large amounts of Carbonate. NOT carbonite.
Answer:
The answer to your question is 1137.45 kJ
Explanation:
Data
mass = 424 g
T1 = 22.6°C
T2 = 149°C
Clw = 4.184 J/g°C
Cv = 2.078 j/g°C
Latent heat = 2257 J/g
Process
1.- Heat of liquid
Heat = (424)(4.184)(100 - 22.6)
Heat = 137308.8 J
2.- Calculate latent heat
Latent heat = (424)(2257)
Latent heat = 956968 J
3.- Heat of vapor
Heat = (424)(2.078)(149 - 100)
Heat = 43172.5 J
4.- Total heat
Heat = 137308.8 + 956968 + 43172.5
Heat = 1137449.3 J = 1137.45 kJ
