<span>b) earths outer iron core
</span><span>A coil of wire that is carrying a current and produces a magnetic field is called a solenoid. So the correct option is option "B", in regards to the question given. The term solenoid was first invented by the famous French physicist named Andre-Marie Ampere. In the terms of a physicist, it indicates a coil that has a far greater lenth than the diameter and is wrapped around a core made of metal to create a uniform magnetic field. If a compass is brought near the wire through which current is passing, it will indicate the direction in which the current is flowing. </span>
To solve this, we need the solubility constant for Hg2Cl2,
which is:
Ksp = 1.4 x 10^-18
The ionic formula would be:<span>
</span><span>Hg2Cl2(s) ---> Hg2 2+(aq) + 2Cl-(aq)</span>
<span>
</span>Therefore the total amounts of ions produced = x M Hg2 2+ and 2x M
Cl-
The formula for Ksp in this case is:<span>
</span>Ksp = [Hg2 2+] [Cl-]^2
1.4 x 10^-18 = (x) * (2x)^2
1.4 x 10^-18 = 4x^3 <span>
</span>x = 7.0 x 10^-7 M = [Hg2 2+]
<span>2x = 14 x 10^-7 M = [Cl-]</span>
Answer:
Aerosol cans carry warnings on their labels that say not to incinerate (burn) them or store the cans above a certain temperature. This problem will sho why it is dangerous to dispose of aerosol cans in a fire. The sa in a used aerosol can is at a pressure of 103 kPa at 25℃.
Hope this helps!!
Good luck!
