Homework Answers
Ans:- In A1
AgNO3 (aq)+ NaCl(aq) ----->AgCl(s) + NaNO3 (aq)
Agcl is white ppt . This formation of ppt is a test for presence of chloride ion and even test of group 1 cations in salt analysis .
Agcl is non -polar because of big size of silver ion with chlorine ion and so it's deform the electrons shells,so this gives its non polar nature so agcl insoluble in water .
In A2 Ag2CO3 is in water considered insoluble in watee but small amount of it 0.032g/l is soluble at 25°C.
In A3 Ag2SO4 is also marginally soluble in water
In A4 AgI is nearly insoluble in water for 3×10^-6 g/l in water at 20°C
So A1 gives most ppt.

I really just need all the equations, please and thank you.
MATERIALS: cene nitric acid, HNO, 3.0M sodium hydroxide, NaOH 6.0 M sulfuric acid, H2SO4 zine metal DI water PROCEDURE: Make sure you record detailed observations after almost every step. You will also need to write the balanced chemical equations for almost every step. Make sure you answer any questions associated with a step 1. Weigh approximately 0.5 g of copper metal and record the weight. Place the copper in...

Experiment 6. the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents....

if a reaction is Oxidation reduction or not. Thanks a lot
OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...

Microscale techniques: In today's experiment we will be using very small amounts of chemical reactants. This method is generally less expensive and more environmentally-friendly than traditional "test tube" chemistry. Some of the waste products produced in today's experiment, particularly those containing lead and barium, are harmful to the environment. By using such small amounts of chemical reactants we generate far less waste than by using larger scale methods. Procedure 1. Put on your safety goggles. Be sure to wear them...
