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 known density of the liquid is
the density of a liquid
Thus, experimental error of 0.0108 g /mL is present.
Thus, Percentage error of 7.31 % is present.
The equation for the reaction describe in the question is NH4Cl (s) --> NH3 (g) + HCl (g)
the equation of heat reaction :
ΔH25° = (ΔH25° NH3 + ΔH25° HCl) - (ΔH25° NH4Cl)
use the table from basic chemical engineering calculations of himmelblau or felder to find ΔH25°.ΔH25° of products minus ΔH25° of reactants.
hope this help
The answer is <span>D. Nonvascular plants. These plants are usually very short and can't grow to be very tall. A good example is moss.

Answer:
Normally, it explains that matter cannot be created or destroyed. It demonstrates different chemical reactions that help show the different transformations of the matter but will never destroy it or create it.
