The Halides experiment is a qualitative analysis type of experiment. Which of the following is not a qualitative observation? Color change 10000 Increase in temperature Formation of a gas (bubbles) Formation of an insoluble solid (precipitate)

PART III: QUESTIONS        Question 1: a ‘law’ in science is a general statement that is the conclusion of multiple observations. Formulate a law that describes what happens when a metal chloride solution is mixed with a silver chloride solution. Question 2: Formulate a law that describes what happens when a metal chloride solution is mixed with a sodium phosphate solution.                   Question 3: If an aqueous solution of titanium chloride, which is clear and purple, is mixed with a silver nitrate solution, predict what precipitate will form. Question 4: If an aqueous solution of titanium chloride, which is clear and purple, is mixed with a sodium phosphate solution, predict what precipitate will form.

Determine the percent yield for the reaction between 46.4 g of ZnS and 13.3 g of O, if 18.4 g of Zno are produced. 2 Zns + 30, → 2 Zno + 2 SO, hp

Why is decoration rather than filtration the preferred method of separating the salt from the mixture

Ex. 110 - Calculating Mass of 3 attempts left Check my work What mass of oxygen is needed to react with 1.79 gal of methanol according to the balanced equation below? (1.00 gal = 3.79 L, and the density of methanol is 0.793 g/mL.) 2 CH3OH() + 3 02g) – 2 CO2g) + 4 H2O(g) If appropriate, express your answer in scientific notion.

Platinum is a precious metal that is used as a catalyst for many important industrial reactions. Platinum can be purified by reacting platinum(IV) bromide solution with aluminium metal. To test this purification process, a student reacted 14.4 kg of aluminium metal with excess platinum(IV) bromide solution. After the reaction was complete, the student had extracted 75.4 kg of platinum metal. From this data, calculate the percent error of this experiment.Hint: Write a balanced chemical reaction equation and calculate the theoretical yield of platinum first.Do not show your work in the space provided.Record only your final answer with the correct number of significant digits and the proper units.

Standardization of Sodium Hydroxide Mass, KHP, g 1.0128 g Initial volume of NaOH in the buret, mL 3.30 mL Final volume of NaOH in the buret, mL 8.30 mL Volume of NaOH added, mL 5.00 mL     Unknown Concentration of Vinegar   Trial 1 Trial 2 Volume of acid, mL 20.50 mL 20.00 mL Initial volume of NaOH in the buret, mL 9.70 mL 8.55 mL Final volume of NaOH in the buret, mL 30.30 mL 28.25 mL Volume of NaOH added, mL 20.6 mL 19.70 mL Use the equation shown to calculate the concentration of the sodium hydroxide from the standardization data. NaOH(aq) + KHP(s) → KNaP(aq) + H2O(l)       2. Calculate the concentration of your acetic acid sample for each trial. What is the average concentration?

Based on this. What was the percentage by mass of water in the sample?
