6. While investigating mole ratios, a group of students collected data for the following chemical reaction: 2 NaOH(aq) +CaCl₂(aq) → 2 NaCl(aq) + Ca(OH)₂(s). The students wondered what would happen if an excess of NaOH was used. Their teacher approved a procedure in which solutions containing 3.00 g of NaOH and 2.10 g of CaCl, were combined. Based on the quantities of these reactants, what amount of Ca(OH)₂(s) is produced? A. 0.0189 mol B. 0.0375 mol C. 0.0500 mol D. 0.1000 mol

Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP.If 33.7 mL of a sodium hydroxide solution are needed to neutralize 1.28 grams of KHP, what is the molarity of the sodium hydroxide solution?

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. → CaC1,₂(aq) + H₂O(1) X Ś

Write the net ionic equation for the reaction when solutions of magnesium sulfide (MgS) and copper (1) nitrate (CUNO3) are mixed given the reaction below: Reaction: MgS (aq) + 2 CuNO3 (aq) → Mg(NO3)2(aq) + Cu₂S (s) Be sure to write out the complete ionic reaction first to find which ions are spectator ions.

The balanced chemical equation for the reaction between calcium hydroxide and hydrochloric acid is: Ca(OH)2 ( aq) + 2 HC1 ( aq )→ CaCl2 ( aq ) + 2 H,0 (1) We can interpret this to mean: 1 mole of calcium hydroxide and |mole(s) of hydrochloric acid React to produce: | mole(s) of calcium chloride and |mole(s) of water

The molar mass of potassium hydrogen phthalate (KHC8H4O4, abbreviation KHP) is 204.22 grams per mole. To determine the molarity of an unknown NaOH solution, a student weighed out 1.32 g of solid KHP and dissolved the solid in 25.4 mL of DI water. The resulting solution was used in a titration with the unknown NaOH solution (3 drops of phenolphthalein was used as an indicator). The balance chemical equation is given below. If the student used 15.06 mL of the unknown NaOH solution in the titration, what is the molarity of the NaOH solution?

In an experiment, a student combines 75.0 mL of a 0.200 M iron (III) chloride solution with 125.0 mL of a 0.250 M sodium carbonate solution. Write a balanced equation for the reaction. What is the limiting reactant? What is the theoretical yield of sodium chloride (in grams)? How many grams of sodium chloride need to be produced in the experiment in order to achieve a yield of 93.75%?
