2 K(s) + 2 H2O(l) → 2 KOH(aq) + H2(g) AH-393 kJ/molræn When 3.9 g of K(s) is added to 200. mL of water at 25°C in a calorimeter, all the K(s) reacts with the water as represented by the equation above. Which of the following is true about the pH of the water after the reaction is complete? (A) pH 7 The pH of the water cannot be determined without additional information.

A coffee cup calorimeter is used to measure the heat of neutralization for this acid - base reaction. Hl(aq) + KOH(aq) -> Kl(aq) + H 2O(l) 40 mL of 0.325 M HI are reacted with 20.0 mL of 0.200 M KOH. Both solutions are initially at 20.500 degrees C. After the reaction has finished, the temperature of the mixture is 21.318 degrees C. The heat capacity of the calorimeter is 29.0 J/oC and the specific heat of the mixture is 4.184 J/goC. The density of the solution is 1.00 g/mL Calculate the Heat of neutralization for this reaction (kJ/mol) (Hint: KOH is the limiting reagent) ? = kj/mol

What is the net ionic equation and ΔHrxn of NaOH(aq) + NH4Cl (aq) -> NaCl(aq) + NH3(aq)+H2O (l)?

Which of the following represents the net ionic equation for the neutralization of the weak acid (HA) acetic acid with sodium hydroxide?HA(aq) + OH−(aq) → H2O(l) + A−(aq)H+(aq) + OH−(aq) → H2O(l)HA(aq) + NaOH(aq) → NaA(aq) + H2O(l)HA(aq) + Na+(aq) → H+(aq) + NaA(aq)H+(aq) + NaOH(aq) → H2O(l) + Na+(aq)

Sodium hydrogen carbonate NaHCO3 , also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid HCl , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCl through this reaction: HCl (aq) + NaHCO3 (aq) → NaCl (aq) + H2O (l) + CO2 (g)The CO2 gas produced is what makes you burp after drinking the solution.   Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 50.mL of a 0.072 M HCl solution. What mass of NaHCO3 would he need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits.
