Answer:
Formula of the compound =
Explanation:
Given,
No. of mole of O = 8.20 mol
No. of mole of P = 3.30 mol
Chemical formula =
Ratio of P and O =
formula of the compound =
has a longer wavelength than x- rays and gamma rays, has a shorter wavelength than infrared and visible light, as the frequency of the wave increase its wavelength decrease
The answer would be C, 1,2,1,2
Answer:
Initial temperature = T₁ = -96.65 °C
Explanation:
Given data:
Initial volume = 4.5 L
Final temperature = 80°C (80+273 = 353 K)
Final volume = 9.0 L
Initial temperature = ?
Solution:
According to Charles law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₁ = V₁ T₂/V₂
T₁ = 4.5 L × 353 K / 9.0 L
T₁ = 1588.5 L.K / 9.0 L
T₁ = 176.5 K
Kelvin to °C:
176.5 K - 273.15 = -96.65 °C
The model that should show the corresct representation of xenon gas is one in which the gas molecules are isolated and monoatomic.
<h3>What is a noble gas?</h3>
A noble gas is a member of group 18 of the periodic table. Noble gases are known not to interact with each other and occur as monoatomic particles.
The images are not shown here hence the question is incomplete. However, we do know that any of the models that show individual monoatomic particles is a representation of xenon gas.
