Can you please answer this two sub questions and show all of the steps to the solution A. What is the correct and complete order for obtaining salt from a mixture of sand and salt?A Adding water - filtration - evaporationB Decant - evaporationC Adding water - evaporationD Adding water - filtrationE Use a magnet - adding water - evaporateF Evaporate- adding waterB. You are in a chemical laboratory and given two beakers. Each contains a clear, colorless liquid. Youare told that beaker I contains sugar dissolved in water and beaker II contains sodium chloride (tablesalt) dissolved in water. You don't know how much sugar or salt is dissolved in each container. Thesafest, most definitive way to determine which beaker has the sugar water and which beaker has thesalt water is to pour off a few mL from each beaker into separate containers and thenAmeasure their densitiesB add more water to each solutionC heat both solutions to drynessD filter both solutions through filter paperE add sugar or salt to each solutionF taste both liquids

The element tin often occurs in nature as the oxide, SnO2 . To produce pure tin metal from this sort of tin ore, the ore usually is heated with coal (carbon). This produces pure molten tin, with the carbon being removed from the reaction system as the gaseous byproduct carbon monoxide. Write the unbalanced equation for this process.
A student mixes four reagents together, thinking that the solutions will neutralize each other. The solutions mixed together are 50.0 mL of 0.100M hydrochloric acid, 100.0 mL of 0.200 M of nitric acid, 500.0 mL of 0.0100 M calcium hydroxide, and 200.0 mL of 0.100 M rubidium hydroxide. Did the acids and bases exactly neutralize each other? If not, calculate the concentration of excess H+ or OH ions left in solution.
Using the general solubility rules discussed in Chapter 7, give the formulas of live substances that would be expected to be readily soluble in water and five substances that would be expected to not be very soluble in water. For each of the substances you choose, indicate the specific solubility rule you applied to make your prediction.
hat is meant by the driving force for a reaction? Give some examples of driving forces that make reactants tend to form products. Write a balanced chemical equation illustrating each type of driving force you have named.
A student was given a 1.6240-g sample of a mixture of sodium nitrate and sodium chloride and was asked to find the percentage of each compound in the mixture. She dissolved the sample and added a solution that contained an excess of silver nitrate. The silver ion precipitated all of the chloride ion in the mixture as silver chloride. It was filtered, dried, and weighed. Its mass was 2.056g. What was the percentage of each compound in the mixture?
The flasks below illustrated three trials of a reaction between varying amounts of zinc and a constant volume of hydrochloric acid solution of constant concentration. The table gives the initial amount of zinc added and the observation at the conclusion of each reaction. Mass of Zinc Added g Observation at Conclusion of Reaction 6.10 Balloon inflated completely Some unreacted zinc remains 2.37 Balloon inflated completely No zinc remains 0.41 Balloon not inflated completely No zinc remains The reaction produces an aqueous solution of zinc chloride and hydrogen gas. Explain the observed results.
On Easter Sunday, April 3, 1983, nitric acid spilled from a tank car near downtown Denver, Colorado. The spill was neutralized with sodium carbonate: 2HNO3(aq)+Na2CO3(aq)2NaNO3(aq)+H2O(l)+CO2(g) a. Calculate H for this reaction. Approximately 2.0 104 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO3 by mass with a density of 1.42 glcm3. What mass of sodium carbonate was required for complete neutralization of the spill, and what quantity of heat was evolved? (Hf for NaNO3(aq) = 467 kJ/mol) b. According to The Denver Post for April 4, 1983, authorities feared that dangerous air pollution might occur during the neutralization. Considering the magnitude of H, what was their major concern?
