(b) What is the colour of iron (III) nitrate solution? What is the heat of solution (qsoln) for the neutralization reaction between NH3 and HCl? A white precipitate forms when BaCl2(aq) is added to an unknown blue solution. Which of the following could be the identity...
About the silver nitrate and copper reaction. we must consider it in two different directions. One would be that copper is a transition metal, so therefore it's multivalent. It can have a 1+ or 2+ charge, right? if you consider it with the 1+ charge, the balanced chemical equation wou...
Determine the colour of silver metal and copper nitrate in water. Compare this to the colour of copper and silver nitrate in water. Table salt, NaCl(s), and sugar, C12H22O11(s), are accidentally mixed. A 4.00-g sample is burned, and 3.40 g of CO2(...
