Answer:
V₂ = 6.0 mL
Explanation:
Given data:
Initial volume = 9.0 mL
Initial pressure = 500 mmHg
Final volume = ?
Final pressure = 750 mmHg
Solution:
According to Boyle's Law
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
V₂ = 500 mmHg × 9.0 mL / 750 mmHg
V₂ = 4500 mmHg .mL / 750 mmHg
V₂ = 6.0 mL
This is seen in the first law of Thermodynamics stating that matter and energy cannot be destroyed nor created.
Answer:
I think that a pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. Mixtures are physical combinations of two or more elements and/or compounds.
Explanation:
Answer:
The correct answer is option e.
Explanation:
The formula used for root mean square speed is:
where,
= root mean square speed
k = Boltzmann’s constant =
T = temperature
M = Molar mass
= Avogadro’s number = 
Root mean square speed of carbon dioxide molecule:

Temperature of the mixture = T =?
Molar mass of carbon dioxide = 44 g/mol = 0.044 kg/mol
T = 533.87 K
Root mean square speed of nitrogen molecule:

Molar mass of nitrogen = 28 g/mol = 0.028 kg/mol

689 m/s is the root-mean-square speed of the nitrogen molecules in the sample.
