Answer: The equilibrium constant for the reaction at 25 °C is 346.7
Explanation:
Formula used :
where,
= standard Gibb's free energy change = -14.50kJ/mol =14500 J/mol
R = universal gas constant = 8.314 J/K/mole
T = temperature = 
= equilibrium constant = ?
Putting in the values we get:
The equilibrium constant for the reaction at 25 °C is 346.7
Mass/volume = density. We know the volume (5 cm cubed) and the density (8.96). We plug these into the equation to find the mass:
M/5 = 8.96
M = 44.8 grams
Answer:
Choices 2 and 4
Explanation:
HCL is formed witthe the elements Hydrogen and Chlorine. Whatever is on the left side of the equation must match up with the right side of the equation.
2. H + Cl --> HCl (we have one hydrogen and one chlorine)
4. 2HCl --> H2 + Cl2 (since the two is distributed to both the H and the Cl, H has 2 and Cl has two on the left side AND on the right side of the equation)
1. Aqeuous or dissolved
2.AgNO3+ NaCl are reactants
3. NaNO3 is precipitate
4. Reaction is endothermic(Delta stands for Heat)
5. Neither a reactant nor a product, MnO2 is a catalyst
