Zn(s) + 2 HCl(aq) → ZnCl,(aq) + H, (g) How many milliliters of 6.50 M HCI(aq) are required to react with 2.85 g Zn(s)?

What volume, in mL, of 0.249 M Li2CO3 solution is required to react with 65.4 mL of 0.422 M HNO3.    2HNO3(aq) + Li2CO3(aq)  →  H2O(l) + LiNO3(aq) + CO2(g)

Sodium hydroxide is used extensively in acid-base titrations because it is a strong, inexpensive base. A sodium hydroxide solution was standardized by titrating 43.00 mL of 0.1425 M standard hydrochloric acid. The initial buret reading of the sodium hydroxide was 1.07 mL, and the final reading was 38.97 mL. What was the molarity of the base solution?

What volume (in mL) of 0.200 M HCI would be required to completely react with 4.40 g of Al in the following chemical reaction? 2 Al(s) + 6 HCl(aq) → 2 AICI (aq) + 3 H₂(g)

if 21.5 g of NaOH is added to 0.800 L of 1.00 M Zn(NO₃)₂, what mass in grams of Zn(OH)₂ will be formed in the following precipitation reaction? 2 NaOH(aq) + Zn(NO₃)₂(aq) → Zn(OH)₂ (s) + 2 NaNO₃ (aq)

Give detailed Solution

How many milliliters of 0.550 M hydrobromic acid are needed to react with 20.00 mL of 0.217 M CSOH? HBr(aq) + CsOH(aq) → CsBr(aq) + H₂O(l)

You have 0.765 g of an unknown acid, H₂A, which reacts with NaOH according to the balanced equation H₂A(aq) + 2 NaOH(aq) → Na2 A(aq) + 2 H₂O(l) If 25.78 mL of 0.461 M NaOH is required to titrate the acid to the second equivalence point, what is the molar mass of the acid? Molar mass = g/mol

A student titrates 0.6769 grams of an unknown acid to the equivalence point with 23.70 mL of 0.1034 M NaOH (aq). The molecular mass of the unknown acid is:

A student needs to dilute a 0.36 M Pb(NO3)20.36 M Pb(NO3)2 solution to make 89.089.0 mL of 0.22 M Pb(NO3)20.22 M Pb(NO3)2. Set up the calculation by placing the values with the correct units into the equation. Then, calculate the volume, in milliliters, of the 0.36 M Pb(NO3)20.36 M Pb(NO3)2 solution that is needed.
