What basic type of reaction is illustrated by the general equation A+B --AB?

Classify the following as acid-base reactions or oxidation-reduction reactions: (a) Na2S(aq)+2HCl(aq)2NaCl(aq)+H2(g) (b) 2Na(s)+2HCl(aq)2NaCl(aq)+H2(g) (c) Mg(s)+Cl2(g)MgCl2(s) (d) MgO(s)+2HCl(aq)MgCl2(aq)+H2+O(l) (e) K3P(s)+2O2(g)K3PO4(s) (f) 2KOH(aq)+H3PO4(aq)K3PO4(aq)+3H2O(l)

Calcium carbonate, CaCO3, can be obtained in a very pure state. Standard solutions of calcium ion are usually prepared by dissolving calcium carbonate in acid. What mass of CaCO3 should be taken to prepare 500. mL of 0.0200 M calcium ion solution?

1. Once a chemical equilibrium has been established, only the forward reaction occurs. only the reverse reaction occurs. the forward and reverse reactions occur at an equal rate. the forward and reverse reactions stop.

ssume a highly magnified view of a solution of HCI that allows you to “see” the HCl. Draw this magnified view. If you dropped in a piece of magnesium, the magnesium would disappear, and hydrogen gas would he released. Represent this change using symbols for the elements, and write the balanced equation.

Write a net ionic equation for any precipitation reaction that occurs when 1 M solutions of the following are mixed. (a) copper(II) sulfate and sodium chloride (b) manganese(II) nitrate and ammonium hydroxide (c) silver nitrate and hydrochloric acid (d) nickel(II) sulfate and potassium hydroxide (e) ammonium carbonate and sodium nitrate

What strong acid and what strong base would react in aqueous solution to produce the following salts? potassium perchlorate, KClO4 sium nitrate, CsNO3 tassium chloride, KCl dium sulfate, Na2SO4

Follow the directions of Question 7 for solutions of the following: (a) silver nitrate and sodium chloride (b) cobalt(II) nitrate and sodium hydroxide (c) ammonium phosphate and potassium hydroxide (d) copper(II) sulfate and sodium carbonate (e) lithium sulfate and barium hydroxide

Write molecular and net ionic equations for the successive neutralizations of each acidic hydrogen of sulfurous acid by aqueous calcium hydroxide. CaSO3 is insoluble; the acid salt is soluble.

The pH values listed in Table 9.1 are generally the average values for the listed materials. Most natural materials, such as body fluids and fruit juices, have pH values that cover a range for different samples. Some measured pH values for specific body fluid samples are given below. Convert each one to [H+], and classify the fluid as acidic, basic, or neutral. a.Blood, pH=7.41 b.Gastric juice, pH=1.60 c.Urine, pH=5.93 d.Saliva, pH=6.85 e.Pancreatic juice, pH=7.85
