This uses something called <span>Le Chatelier's principle. It states essentially that any stress put upon a system will be corrected.
In more simple terms, it means that in an equilibrium, such as the equation N2(g) + 3H2(g) <=> 2NH3(g), removing a reactant will cause the system to create more of said reactant to compensate for its loss, or adding excess reactant will cause the system to remove some of the added reactant. For future reference, the same principle applies to products in an equilibrium as well.
In this case, hydrogen gas is a reactant, and hydrogen is being removed. According to </span><span>Le Chatelier's principle, the system will shift to create more hydrogen gas. In essence, it will shift in the direction of the hydrogen gas, so there will be a shift toward the reactants.
To clear something up, Keq will not change, as it is a constant value with constant conditions (such as temperature, pressure, etc.).</span>

energy source
Explanation:
After wire and filament have been connected, for the conduction of electricity, an energy source is required.
In the energy source, electrical energy is produced.
- The energy source can be a simple electrochemical cell.
- It can be a generator.
- It can also be current from the national grid.
- The energy source produces current which is carried in wire and it powers the filament

Answer:-
H2SO3 (aq)
Explanation:-
NaCl, KOH and HCl ionic compounds.
Ionic compounds dissociate into ions in water.
Ions can carry electricity in water. So NaCl, KOH and HCl are all strong electrolytes.
H2SO3 is not a strong acid and dissociates to a small extent into ions in water.
Hence number of ions formed is less. Hence it is a weak electrolyte.
Answer:
(a). 5.4 × 10^23 atoms.
(b). 0.8928 moles Ni.
Explanation:
The first thing to do is to convert surface area from the in^2 to cm^2 and also the thickness unit to cm.
Therefore, 200 in^2 = 1290.3 cm^2 and 0.002 in = 0.00508 cm.
The next thing to do is to calculate the volume by using the formula below;
Volume= A × d. Where A = area and d = thickness.
Then, volume = 1290.3 × 0.00508= 6.55 cm^3.
Although not given but the Density if Nickel = 8 g/cm^3.
We know that the formula for Calculating density = mass / volume. So, we have ; mass = density × volume.
Mass= 8 × 6.55 = 52.4 g.
(a). The number of atoms of Nickel= moles × Avogrado's number.
Numbers of moles= mass / molar mass.
==> 52.4 / 58.6934 = 0.8928 moles.
Then, the number of atoms of Nickel = 0.8928 × 6.02 × 10^23.
= 5.4 × 10^23 atoms.
(b). The number of moles of Nickel has been Calculated in (a) above to be = 0.8928 moles Ni.
