Part A- Products In Part A, you added solutions of NaOH (0.5 M, and then concentrated). This is represented in the image below: NaOH (0.5 M) Start with 0.5 ml of [Co(OH,),]?* (aq) +2Cl (aq) Product 3 (Co(OH,)JCI, (0.1 M) NaOH (conc.) Product 7 Determine the identities of Products 3 and 7 Product 3: (Co(OH)2(OH2)4] = Product 7: (Co(OH)2)

How do you do part D of the question?

With explanation please

can you please answer the chem questions on the image attached below?  i have included another picture for the choices available for first one thank you so very much

Calcium Benzoate: a) A sample of saturated CaBz2 solution is at equilibrium. The initially-prepared concentrations are [Ca?+]; = A and [Bz]; =B. This sample is allowed to saturate, and then the remaining solid is filtered out. As determined by titration, the final benzoate ion concentration in solution is [Bz]:= C. What is the solubility product of CaBz2, in terms of A, B, and C?| b) In our lab experiment, the CaBz2 solution is saturated at equilibrium before titration. Why must the CaBz2 solutions be saturated?

Scientists determine the quantity of atmospheric sulfur dioxide (SO, ), a large contributor to acid rain, by an indirect titration. First, a scientist collects a sample of air and reacts it with hydrogen peroxide (H, 0, ) to form a solution of sulfuric acid ( H, SO, ). Then, the amount of H, SO, produced is determined by titration with a sodium hydroxide solution (NaOH) of known concentration. H,O,(aq) + SO,(g)– H, SO,(aq) H, SO, (aq) + 2 NaOH(aq) 2 H, O(1) + Na, SO4(aq) Suppose Lane collects a 608.0 g sample of air that is known to contain SO, and reacts it with excess H,O, . A volume of 17.8 mL of 0.010 M NaOH is required to neutralize the H, SO, produced. Calculate the mass percent of SO, in the air sample. mass percent: % SO2
