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
.
Complete Question
An aluminum "12 gauge" wire has a diameter d of 0.205 centimeters. The resistivity ρ of aluminum is 2.75×10−8 ohm-meters. The electric field in the wire changes with time as E(t)=0.0004t2−0.0001t+0.0004 newtons per coulomb, where time is measured in seconds.
I = 1.2 A at time 5 secs.
Find the charge Q passing through a cross-section of the conductor between time 0 seconds and time 5 seconds.
Answer:
The charge is
Explanation:
From the question we are told that
The diameter of the wire is
The radius of the wire is
The resistivity of aluminum is
The electric field change is mathematically defied as
Generally the charge is mathematically represented as
Where A is the area which is mathematically represented as
So
Therefore
substituting values
From the question we are told that t = 5 sec
