<u>Given:</u>
EMF = 0.88 V
Strength of magnetic field, B = 0.075 N/A-m
Velocity, v = 4.20 m/s
<u>To determine:</u>
The length of wire, L
<u>Explanation:</u>
The EMF is related to strength of the magnetic field B as:
EMF = L*B*v
L = EMF/B*v = 0.88/0.075*4.20 = 2.79 m
Ans: The length of the wire is around 2.8 m
Answer:
SO2 => sulphur dioxide
P2CL5 =>Diphosphorus pentachloride
N2O4 =>Dinitrogen tetroxide
Standard temperature is 273 K
Standard pressure is 1 atm
We use the ideal gas equation to find out density of nitrogen gas in g/L
Ideal gas equation:
Molar mass of
Pressure = 1 atm
Temperature = 273 K
= 1.25 g/L
Therefore, density of nitrogen gas at STP is 1.25 g/L
.3999 moles
The ideal gas law: PV = nRT
155 degrees Celsius = 428 Kelvins
n = PV/RT
n = 2.80 atm x 5.00 L/0.0821 (gas constant) x 428 K
= 0.398 moles
