Answer:
2.0*
Explanation:
Let us calculate total moles (air + CO)
moles (n) = PV /RT
P = 755 torr/760 = 0.9934 atm
V = 1.00 L
R = gas constant
T = 23°C + 273 = 296 K
So,
total moles (n) = 0.9934 x 1.00/0.0821 x 296 = 0.041 moles
mole fraction of CO = 8.1 x
moles of CO =8.1 x *0.041
=3.31 x moles
number of molecule of CO =3.31 x *(6.0233x )
= 2.0*
Answer:62m/s
Explanation:
Initial velocity(u) =12m/s
Acceleration(a)=2.5m/s2
Time(t)=20seconds
Final velocity(v)=?
V=u+axt
V=12+2.5x20
V=12+50
V=62m/s
The answer would be 5.6x10^5
Answer:Frequency = 3.525 Hertz
Explanation:In static equilibrium, kd =mg
Where k= effective spring constant of the spring.
mg= The weight of the car.
d= static deflection.
Therefore, w =SQRTg/d
w = SQRT 9.81/0.02
w= 22.15 rad/sec
Converting to Hertz unit for frequency
1 rad/s = 0.1591
22.15rad/s=?
22.15 × 0.1591= 3.525 hertz
Answer:
Duration
Explanation:
Because duration is not a factor, but it's the outcome or effect or observation from the reaction used to give the rate of reaction
