Answer:
The only thing that will not affect the potential is the adition of solid Sn.
Explanation:
The potencial of a cell is linked to the concentration of the substances involved in the reactions by the equation of Nernst. So a change of one of them would change the cell potential.
The Keq for this reaction is:
<em>Sn is not included because it's in solid state. </em>
As can be seen, changing the concentrations of H2 (increasing the pressure), H+ (lowering the pH) or Sn2+ will affect the potential.
The only thing that will not affect it is the adition of solid Sn.
The dependent variable is the variable that changes based on the independent variable (the manipulated variable).
Answer:
Calcium carbonate and hydrochloric acid
Explanation:
The reaction of Calcium carbonate and Hydrochloric acid leads to the formation of Calcium Chloride and Carbon (IV) Oxide gas.
CaCO3 + 2HCl => CaCl2 + CO2 + H2O

Answer:
sp2
Explanation:
Orbital hybridization is defined as the changes in the orbitals of atoms when they pair with electrons of other atoms to form chemical bonds.
C atoms in C2Cl4 or tetrachloroethene have a total of three bond pairs, two with each chlorine atom and one with other carbon atom and zero lone pairs. Thus, C atoms in C2Cl4 is sp2 hybridized.
Hence, the correct answer is "sp2".
