If six moles of hydrogen chloride (HCl) react with plenty of aluminum, how many moles of aluminum chloride (AlCl3) will the reac
1 answer:
Answer:
Two moles of aluminum chloride are produced when six miles of hydrogen Chloride
react with plenty of aluminum
Explanation:
6 Moles of will only react with 2 moles of
irrespective of the number of moles of each compound present. The reaction wiil take place in this ratio only. The products produced will be 2 moles of
and 3 moles of
this ratio will also be constant.
So, six moles of hydrogen chloride will react with plenty of aluminum to produce many 2 moles of aluminum chloride
.

Answer:
Explanation:
ω =
k = 2.5 N/m
m = 10 kg
ω = .5 rad /s
x(t) = A cos(ωt + φ₀)
When t = 0 , x(t) = 0
0 = A cos(ωx 0 + φ₀)
cos φ₀ = 0
φ₀ = π /2
x(t) = A cos(ωt +π /2 )
Putting the value of ω
x(t) = A cos(.5 t +π /2 )
Differentiating on both sides
dx(t)/dt = - .5 A sin(.5 t +π /2 )
v(t) = - .5 A sin(.5 t +π /2 )
Given t =0 , v(t) = -5 m/s
-5 = - .5 A sin(.5 x0 +π /2 )
-5 = - .5 A sinπ /2
A = 10 m
x(t) = 10 cos( .5 t +π /2 )
b )
when t = π ( 3.14 s )
x(t) = - 10 m
when t = 2π ( 6.28s )
x(t) = 0
when t = 3π ( 9.42 s )
x(t) = 10 m
and so on
Explanation:
A = Wavelength
The distance between two consecutive crest or trough is wavelength
B = Amplitude
The maximum distance covered by the particles of a wave
C = Rest postion/equilibrium
When there is no disturbance in the medium
D = Trough
It is the displacement in negative direction
E = Crest
It is the displacement in positive direction
(A) The relationship between the wavelength and frequency is given by :
There is an inverse relationship between wavelength and frequency.
(B)
When the frequency is decreased, the wavelength of a wave increases.
