(a)
Interpretation:
The balanced equation for the reaction of treatment of finely divided gold with CN-(aq) in the presence of O2 (g) should be written.
Concept introduction:
The balanced chemical equation can be written by following a few steps:
Step 1: Writing the correct skeleton and molecular formula for the element or molecules on either side of the equation.
Step 2: Counting the
Step 3: Balancing the number of that atom or group on either side which has large atoms in number.
Step 4: Using the correct coefficients to balance the number of atoms on both sides.
(b)
Interpretation:
The balanced equation for the reaction of treatment of finely divided zinc metal with solution formed in part (a) should be written.
Concept introduction:
The balanced chemical equation can be written by following a few steps:
Step 1: Writing the correct skeleton and molecular formula for the element or molecules on either side of the equation.
Step 2: Counting the number of atoms of each element on either side of the equation.
Step 3: Balancing the number of that atom or group on either side which has large atoms in number.
Step 4: Using the correct coefficients to balance the number of atoms on both sides.

- Pls help asaparrow_forwardPredict the major products of this reaction: ་ ་ + H NaOH ? Δ excess Note that the second reactant is used in excess, that is, there is much more of the second reactant than the first. If there won't be any products, just check the box under the drawing area instead.arrow_forwardP A student claims the right-hand side of the reaction in the drawing area below shows the product of a Claisen condensation. • If the student is correct, complete the reaction by adding the necessary organic reactants to the left-hand side, and by adding any necessary reagents and reaction conditions above and below the arrow. • If the student is incorrect, because it's not possible to obtain this product from a Claisen condensation, check the box under the drawing area instead. those that will minimize any byproducts or competing • Note for advanced students: If you have a choice, use the most efficient reactants and reagents reactions. - ☐ ☐ : ☐ + I Х Click and drag to start drawing a structure.arrow_forward

What are the reactants missing from the left-hand side? Draw them below. ? NaOH Δ If there aren't any reactants that would lead to these products under the reaction conditions given, just check the box under the drawing area. Note for advanced students: don't worry if the reactants you propose might also make some other products under these reaction conditions. Just make sure the product above is one of the major products.arrow_forwardPlease help! I need to identify four labeled unknown bottles based off of their colors doing titration using phenlphtalein. I've included my answers, but I wanted to make sure they were correct and if not, what will be correct thank you in advance.arrow_forward
