2 NaOH(aq) + CI2(g) --> NaCI (aq) + NaCIO (aq) + H20 (I) If you have 1.23 mol of NaOH in solution and 1.47 mole of CI2 gas available to react, which is the limiting reactant? How many moles of water could be obtained?

The balanced equation below shows a simple way of manufacturing hydrogen gas in lab (you've done thisl). For your convenience, the molar mass of each substance is shown below their formulas (in purple). Use this information to make the requested calculation: 2 Al(s) + 6 HCI(aq) -> 2 AICI3(aq) + 3 H2(g) 26.982 36.461 133.341 2.016 What volume of hydrogen gas, in mL, would be produced by the reaction of 922 mg of hydrochloric acid with excess aluminum metal?

A 30.00-mL volume of aqueous sulfuric acid, H2SO4, is titrated using 0.200 M NaOH and an indicator that turns color only after all the sulfuric acid protons have reacted with OH- ions. The solution turns color when 48.32 mL of base has been added. What is the molar concentration of the sulfuric acid?

Walter White requires a sulfuric acid (Strong acid) solution to use in a very important synthetic reaction.  He finds a bottle labeled H2SO4, but by some strange turn of events, he cannot remember the concentration.  He decides to perform a titration to determine the concentration of the H2SO4.  He pours 22.20 mL of his unknown sulfuric acid solution into a flask and finds that it requires 29.50 mL of 0.57 M KOH (strong base) to reach the endpoint.  What is the concentration of Walter White's sulfuric acid solution? (Enter your numeric answer only, do not use scientific notation, enter 2 decimal places with your answer) For reference: KOH = 56.106g/mol H2SO4= 98.079g/mol Avagadro's number 6.022x1023

A 30.00 mL sample of an aqueous solution of CaI2 reacts with excess NaOH according to the following reaction: 2NaOH(aq) + CaI2(aq) ---> Ca(OH)2(s) + 2NaI(aq) If the mass of the precipitate is 0.489g, what is the concentration of the CaI2 solution?

Sodium hydrogen carbonate (NaHCO,), 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 (HCI) , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: HCl(aq) + NaHCO;(aq) → NaCl(aq) + H,O(1) + CO,(g) The CO, 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 100. mL of a 0.048 M HCI solution. What mass of NaHCO, would he need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits. x10

Milk of magnesia (magnesium hydroxide) reacts with stomach acid (hydrochloric acid).  Calculate the molarity of the stomach acid if 26.0 mL of 0.200 M milk of magnesia is used to titrate 35.0 mL of stomach acid using the following balanced equation.   Mg(OH)2 + 2HCl ⟷ MgCl­2 + 2H2O Group of answer choices 0.297 M 0.0743 M 0.269 M 0.148 M 0.135 M

1. The following reaction occurs in your lab: You have 225.0 mL of 0.345 M Na3PO4. How many grams of precipitate can are made? Balanced Rxn: 3 CaCl2 (aq) + 2 Na3PO4 (aq) → 6 NaCl (aq) + Ca3(PO4)2 (s) - 2. How many mL of a 0.220 M solution of KOH will be required to titrate 38.00 mL of a 0.0566 M solution of H3PO4? Balanced Rxn: H3PO4 (aq) + 2KOH (aq) → K2HPO4 (aq) + 2H2O (1)

A titration is performed to determine the amount of sulfuric acid, H2SO4,, in a 6.5mL sample taken from a car battery. About 50mL of water is added to the sample, and then it is titrated with 43.37mL of standard 0.5824 molar NaOH solution. How many moles of sulfuric acid are present in the original sample?
