Write a net ionic equation for the reaction that occurs when lead(II) carbonate and excess hydrochloric acid (aq) are combined.

Complete and balance the equation for the single displacement reaction between sodium and lead (II) nitrate. Phases are optional. Balanced equation: Na(s)+Pb(NO3)2(aq) =

Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP.What volume of a 0.370 M barium hydroxide solution is needed to exactly neutralize 4.24 grams of KHP ?

A piece of chalk (mainly calcium carbonate) is placed in 250. mL of 0.364 M HCl.All the CaCO3 reacts, releasing carbon dioxide gas and leaving 250. mL of a clear solution.35.00 mL of the solution is pipetted into another flask.65.9 mL of 0.0524 M NaOH is required to titrate the HCl remaining in this 35.00-mL portion. What was the original mass of CaCO3 in the piece of chalk?

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. [] + KClO(aq) + H,O(1) · X Ś

A solution of NaCl(aq) is added slowly to a solution of lead nitrate, Pb(NO3)₂(aq), until no further precipitation occurs. The precipitate is collected by filtration, dried, and weighed. A total of 10.67 g PbCl₂ (s) is obtained from 200.0 mL of the original solution. Calculate the molarity of the Pb(NO3)₂(aq) solution. concentration: M

write a net ionic equation for the reaction that occurs when manganese (II) suflide and excess hydrochloric acid (aq) are combined

Write the balanced NET ionic equation for the reaction when HClO₃ and Ba(OH)₂ are mixed in aqueous solution. If no reaction occurs, simply write only NR.

The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium hydrogen phthalate (abbreviated as KHP). KHP is an acid with one acidic hydrogen and a molar mass of 204.22 g/mol. In the titration, 48.82 mL of the sodium hydroxide solution was required to react with 0.7540 g KHP. Calculate the molarity of the sodium hydroxide. Molarity = ___________ M

What is the balanced net ionic chemical equation between Cu^2+ (aq) and I^- (aq)?
