May 14, 2024 · 1 Answer. Sorted by: 4. The reaction we have is: A(aq) + 2B(aq) C(aq) + 2D(l) The standard molar change in enthalpy for this reaction is given by: Δ¯ Ho = cΔ¯ Ho fC + dΔ¯ Ho fD − (aΔ¯ Ho fA + bΔ¯ Ho fB) Substituting the values from the table: Δ¯ Ho = − 1387.10 + 2( − 285.83) − [ − 909.27 − 2(469.15)]
May 23, 2024 · Reaction with Potassium Iodide. When you mix lead nitrate with potassium iodide, a yellow precipitate of lead(II) iodide forms. This is a double displacement reaction. Equation: Pb(NO₃)₂ + 2KI → PbI₂ + 2KNO₃; Reaction with Sodium Hydroxide. When you add sodium hydroxide to lead nitrate, it forms a white precipitate of lead(II) hydroxide.
May 6, 2024 · However, if water, as ice, liquid, or vapour, encounters sodium metal (Na), the atoms will be redistributed to give the new substances molecular hydrogen (H 2) and sodium hydroxide (NaOH). By this, we know that a chemical change or reaction has occurred.

May 6, 2024 · Determine the pOH: pOH = -log [OH-] Calculate the pH: pH = 14 – pOH. For example, if you have a 0.1 M solution of NaOH, the concentration of OH- ions in the solution is 0.1 M. To find the pOH, take the negative logarithm (base 10) of the hydroxide ion concentration: pOH = -log [0.1] = 1.
