Question
Please make the answers simple , thanks :
Vinegar is a homogenous aqueous solution of 5 - 6 % acetic acid. What is the solvent? A solution is made by dissolving glucose in water. What is the solvent and what is the solute? The solubility of a compound is 2.5 g in 100 mL of water at 25degree C. if you place 1.12 g of the compound in a 50. mL volumetric flask at 25degree C and add sufficient water to fill the flask to the mark, will the solution be saturated, unsaturated, or supersaturated? Benzene is C6H6. Which of the following solutes would be the most soluble in benzene? NaCI, ethanol (CH3CH2 - OH) or butane (CH3CH2CH2CH3). Hint, to answer this remember the phrase "like dissolves like. Which pairs of liquids are likely to be miscible? water and CH3 - OH water and C6H6 CCI4and C6H14 CCI4and H3 - OH Near a power plant, warm water is often discharged into a river. Sometimes, dead fish are observed in the area. Why do you think this is? if a bottle of beer is allowed to stand for several hours after being opened, it becomes flat. Why do you think this is? Would you expect the solubility of ammonia gas in water at 2 atm to be A) greater, B) the same, or C) lower than the solubility it would have at 0.5 atm? Describe how you would make the following solutions. 500.0 g of a 5.32% w/v H2S solution in water. 342.0 g of a 0.443% w/w benzene solution in toluene 12.5 g of a 34.2% w/w dimethyl sulfoxide solution in acetone. Describe how you would make the following solutions. 280. mL of a 27% v/v solution of ethanol in water 435 mL of a 1.8% v/v solution of ethyl acetate in water 1.65 L of an 8.00% v/v solution of benzene in chloroform.Explanation / Answer
36) Water
37)solvent is water, solute is glucose
38) saturates
39) butane
40) A, C
41) pollutants
42) Reaction with the air causes the compound to break down
43) lower
44A) You would mix 500g of H2S solution in 9.4 L of water. Solve B and C in a similar fashion :)
.0532=500.0g / v water
v water =500g/.0532
H2S= 9398 mL or 9.4 L
45A) You would mix 280 mL of ethanol in 1 L of water. (Work B and C in a similar fashion :)
.27= 280 / v
v= 1037 mL or 1.0 L
