Help plsss - Potassium iodide and lead(II) nitrate solutions react together to form solid lead(II) iodide and aqueous potassium nitrate: 2Kl(aq) + Pb(NO3)2(aq) → Pbl (s) + 2KNO3(aq)
In each of the following cases, carry out the calculations to determine the quantities required.
a) If 1.0 mol of potassium iodide reacts with 1.0 mol of lead(II) nitrate, determine which reactant is in
excess and by how many mol.
b) If 0.50 mol of potassium iodide reacts with 2.0 mol of lead(II) nitrate, determine which reactant is in
excess and by how many mol.
c) If 1.00g of lead(II) nitrate reacts with 1.50g of potassium iodide, determine which reactant is in
excess and the mass of lead(II) iodide that forms.

Write a paragraph that provides examples of each stage of volcanic activity, a description of the volcano, and facts about each stage.

The conventional equilibrium constant expression (kc) for the system below is: 2icl(s) ⇄ i2(s) + cl2(g) [cl2] ([i2] + [cl2])/2[icl] [i2][cl2]/[icl]2 none of the listed answers are correct [i2][cl2]/2[icl]

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
