Answer:
65.2L
Explanation:
Using the general gas equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (Litres)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (Kelvin)
According to the information provided in this question,
P = 1.631 atm
V = ?
n = 4.3 moles
T = 28°C = 28 + 273 = 301K
Using PV = nRT
V = nRT/P
V = 4.3 × 0.0821 × 301 ÷ 1.631
V = 106.26 ÷ 1.631
V = 65.15
Volume of the gas = 65.2L
Answer:
<h3>The answer is 0.79 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 2.56 g
volume = 3.25 mL
We have
We have the final answer as
<h3>0.79 g/mL</h3>
Hope this helps you
When studying quantum mechanics, the de Broglie wavelength is a key idea. De Broglie wavelength is the wavelength () that is connected to an item in relation to its momentum and mass.
Typically, a particle's force is inversely proportional to its de Broglie wavelength.
Assuming that the smallest measurable wavelength in an experiment is 0.830 fm , what is the maximum mass of an object traveling at 171 m⋅s−1 for which the de Broglie wavelength is observable?
We know:
- The shortest wavelength that is detectable, λm = 0.330 fm
- the object's velocity, v = 157 m/s
According to the following equation, an object's de-Broglie wavelength solely depends on its momentum:
λ = h/p = h/m*v, where,
- h = 6.626 × 10^(−34) J⋅s
- p = mv is the object's momentum. It is based on the moving object's mass, m, and velocity, v.
By rearranging the above equation, the object's mass can be written as:
m = h/λv
The maximum mass and the minimum de Broglie wavelength of the item are inversely correlated because the two quantities are inversely proportional to one another. When we enter the values provided, we get:
m = {6.626×10^(−34) J⋅s} / {0.330 fm × 157 m/s}
≈ 1.28×10^(−20) kg

Answer:
Removing O₂, means removing one of the reactants and the system would counteract this effect by producing more O₂, thereby shifting the equilibrium position to the left and favouring the backward reaction.
Explanation:
The principle that explains how changes in temperature, Concentration and Pressure of reactants or products of a reaction at equilibrium affect the equilibrium position of the reaction is the Le Chatelier's principle.
The Principle explains that a system/process if a system/process which is at equilibrium is disturbed/perturbed/constrained by one or more changes (in concentration, pressure or temperature), the system would shift the equilibrium position to counteract the effects of this change.
Removing O₂, means removing one of the reactants (changing its concentration) and the system would counteract this effect by producing more O₂, thereby shifting the equilibrium position to the left and favouring the backward reaction.
