Answer:
The answer to your question is V2 = 867.3 mL
Explanation:
Data
Volume 1 = V1 = 400 ml
Temperature 1 = T1 = 22°C
Pressure 1 = P1 = 760 mmHg
Volume 2 = V2 = ?
Temperature 2 = T2 = 30°C
Pressure 2 = P2 = 360 mmHg
Process
1.- Convert Celsius to Kelvin
T1 = 22 + 273 = 295°K
T2 = 30 + 273 = 303°K
2.- Use the Combined gas law
P1V1/T1 = P2V2/T2
- Solve for V2
V2 = P1V1T2 / T1P2
- Substitution
V2 = (760 x 400 x 303) / (295 x 360)
- Simplification
V2 = 92112000 / 106200
-Result
V2 = 867.3 mL
Answer:
Scientists believe that comets are the debris left from the solar nebula which condensed to form the Sun and planets in our solar system. Most comets are thought to originate in a huge cloud called the Oort Cloud. ... Comets follow a regular orbit around the Sun.
Hope this helps! :)
Explanation:
Answer:
0.0468 g.
Explanation:
- The decay of radioactive elements obeys first-order kinetics.
- For a first-order reaction: k = ln2/(t1/2) = 0.693/(t1/2).
Where, k is the rate constant of the reaction.
t1/2 is the half-life time of the reaction (t1/2 = 1620 years).
∴ k = ln2/(t1/2) = 0.693/(1620 years) = 4.28 x 10⁻⁴ year⁻¹.
- For first-order reaction: <em>kt = lna/(a-x).</em>
where, k is the rate constant of the reaction (k = 4.28 x 10⁻⁴ year⁻¹).
t is the time of the reaction (t = t1/2 x 8 = 1620 years x 8 = 12960 year).
a is the initial concentration (a = 12.0 g).
(a-x) is the remaining concentration.
∴ kt = lna/(a-x)
(4.28 x 10⁻⁴ year⁻¹)(12960 year) = ln(12)/(a-x).
5.54688 = ln(12)/(a-x).
Taking e for the both sides:
256.34 = (12)/(a-x).
<em>∴ (a-x) = 12/256.34 = 0.0468 g.</em>
