Suppose you pour 20 mL of silver nitrate into a beaker with 80 mL of water (H20) in it. You also pour 20 mL of silver nitrate into a separate beaker, but this one contains 80 mL of salt water (NaCl). Is the percent strength of the silver nitrate the same in both of these solutions
considering this given equation ch4 g 3 cl2 g- chcl3 g 3 hcl g determine how many grams of methane is required to
Given the values of ?Hfo in kJ/mol and So in J/mol K given below, calculate the value of ?Go in kJ for the reaction at 298 K.: NH4Cl(s) => HCl(g) + NH3(g) ?Hfo (NH4Cl) = -312.4 ?Hfo (HCl(g)) = -91.5 ?Hfo (NH3) = -44.5 So NH4Cl(s) = 93.9 So HCl(g) ..
