Answer:
124.91mL
Explanation:
Given parameters:
P₁ = 1.08atm
V₁ = 250mL
T₁ = 24°C
P₂ = 2.25atm
T₂ = 37.2°C
V₂ = ?
Solution:
To solve this problem, we are going to apply the combined gas law;
![\frac{P_{1} V_{1} }{T_{1} } = \frac{P_{2} V_{2} }{T_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7D%20V_%7B1%7D%20%7D%7BT_%7B1%7D%20%7D%20%20%20%3D%20%20%5Cfrac%7BP_%7B2%7D%20V_%7B2%7D%20%7D%7BT_%7B2%7D%20%7D)
P, V and T represents pressure, volume and temperature
1 and 2 delineates initial and final states
Convert the temperature to kelvin;
T₁ = 24°C, T₁ = 24 + 273 = 297K
T₂ = 37.2°C , T₂ = 37.2 + 273 = 310.2K
Input the variables and solve for V₂
![\frac{1.08 x 250}{298} = \frac{2.25 x V_{2} }{310.2}](https://tex.z-dn.net/?f=%5Cfrac%7B1.08%20x%20250%7D%7B298%7D%20%3D%20%5Cfrac%7B2.25%20x%20V_%7B2%7D%20%7D%7B310.2%7D)
V₂ = 124.91mL
(4) structural formula, isomers are differently structured forms of the same compound.
Answer:
The Bohr Model is very limited in terms of size. Poor spectral predictions are obtained when larger atoms are in question. It cannot predict the relative intensities of spectral lines. It does not explain the Zeeman Effect, when the spectral line is split into several components in the presence of a magnetic field.
Explanation:
Balanced chemical equation for the reaction is:
2S
(g) +
(g)+ 2
O (l) ⇒![H_{2} S_{} O_{4}](https://tex.z-dn.net/?f=H_%7B2%7D%20S_%7B%7D%20O_%7B4%7D)
Moles of
formed is 5.75 moles.
Moles of oxygen used is 5.75 moles in the reaction.
Explanation:
Data given:
moles of S
= 11.5 moles
moles of
= ?
Moles of
needed =?
balanced equation with states of matter =?
Balanced chemical reaction under STP condition is given as:
2S
(g) +
(g) + 2
O (l) ⇒
From the balanced reaction 2 moles of sulphur dioxide reacted to form 1 mole of sulphuric acid:
so, from 11.5 moles of S
, x moles of
is formed
![\frac{1}{2} =\frac{x}{11.5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%20%3D%5Cfrac%7Bx%7D%7B11.5%7D)
2x = 11.5
x = 5.75 moles of sulphuric acid formed.
From the balanced reaction 1 mole of oxygen reacted to form 1 mole of sulphuric acid.
when 11.5 moles of Sulphur dioxide reacted then oxygen in the reaction is 5.75 moles.
