Answer:
The new pressure is 456.76 mmHg
Explanation:
Step 1: Data given
The initial volume of the gas = 5.80 L
The initial pressure of the gas = 1.00 atm
The volume of the gas increases to 9.65 L
The temperature is kept constant
Step 2: Calculate the new pressure
P1*V1 = P2¨V2
⇒with P1 = the initial pressure of the gas = 1.00 atm
⇒with V1 = the initial volume of the gas = 5.80 L
⇒with P2 = the new pressure = TO BE DETERMINED
⇒with V2 = the increased volume of the gas = 9.65 L
1.00 atm * 5.80 L = P2 * 9.65 L
P2 = (5.80 / 9.65)
P2 = 0.6010 atm
Step 3: Convert pressure from atm to mm Hg
0.6010 atm * 760 mmHg = 456.76 mmHg
The new pressure is 456.76 mmHg
Answer:
SO2
Explanation:
Dipole-Dipole exist between parmanent dipoles in a molecule. THis means that molecule must have a parmanent dipole moment in it.
Example - HCl
Hydrogen bonding is an attraction between lone pair of an electronegative element and H atom of same or different molecule. H must be covalantly attached to either F, N or O.
Example - H2O
Among the molecules given in the list only SO2 and H2O exihibits parmanent moment. As BCl3 , CBr4 and H2 are symmetric compounds.
Since, SO2 cannot exihibit H- bonding only dipole-dipole forces as its strongest intermolecular force.
<span>According to Faraday's Law,
W = I t e / F
Where,
W = Amount deposited = ?
I = Current = 3 A
t = Time = 965 s
e = Chemical equivalence = 52/3 = 17.33
F = Faraday's Constant = 96500
Putting Values,
W = (3 × 965 × 17.33) ÷ 96500
W = (50170.35) ÷ 96500
W = 0.52 g
As we know,
Moles = mass ÷ M.mass
Putting values,
Moles = 0.52 ÷ 52
Moles = 0.01</span>
The experimental control is the standard used as a comparison for the experimental groups.
For example, you may be trying to find out how different types of disinfectants affect bacterial growth. The control group would receive <em>no</em> disinfectant whereas the experimental groups would be the ones on which the disinfectants were tested.
Hope this makes sense!
