The student would find the water and sand, because salt dissolves in water unless it was ocean water or sea water

Only salt and sand.
This is because the water would evaporate during the filtration process, leaving only sand and the salt it left behind.
Hope this helps :)

How many grams of KBr are required to make 550. mL of a 0.115 M KBr solution?
In-s [12.5K]

Molarity is expressed as the number of moles of solute per volume of the solution. For example, we are given a solution of 2M NaOH this describes a solution that has 2 moles of NaOH per 1 L volume of the solution. We calculate as follows:

0.115 M = n mol KBr / .55 L solution

n = 0.06325 mol KBr

mass = 0.06325 mol KBr (119 g / mol) = 7.53 g KBr

Which of the following statements are True about the experimental process used in the Diels Alder reaction?
vovikov84 [41]

Here we have to get the correct statements among the given, applicable for Diels-Alder reaction.

The true statements in case Diels-Alder reaction are-

1. An excess of Maleic anhydride is used.

2. The I.R. of the products are indistinguishable.

The Diels-Alder reaction is the most is the most important cyclo-addition reaction in organic chemistry. These are addition reactions in which ring systems are formed without eliminating any compounds.

There remains one diene and one dienophile. The reaction is reversible in nature and requires elevated temperature to obtain its transition state. The reaction rate become faster in certain condition like using of polar solvents.

Among the given statements the following statements are true-

1. An excess of maleic anhydride (the most effective di-enophile) is used to process the reaction in forward direction.

2. The products obtain in this reaction are stereoisomers thus are indistinguishable by infrared spectroscopy (IR).

The statements which are not true for the Diels-Alder reaction:

3. The re-crystallization of the products by any polar solvent like methanol is not feasible as it will cause the retro reaction due to stability of the transition state in polar solvent.

4. Cleaning of glassware are compulsory for any reaction it is not specifically true for Diels-Alder reaction.

5. The reaction occurs at elevated temperature thus flame is required.

If you were to assume a 95% yield for the formation of the phosphonium ion, how many milligrams of benzyl chloride and triphenyl
luda_lava [24]
I am attempting the problem for phosphonium Ion rather than its chloride salt. The chemical equation is shown below along with molar masses in mg.

First of all we will calculate the amounts of reactants required for the synthesis of 220 mg of phophonium ion. Calculations for both reactants is as follow,

For Benzyl chloride,
\frac{353420 mg of Phosphonium is formed by reacting}{220 mg of Phosphonium will be formed by} = \frac{126580 g of benzyl chloride}{X}

Solving for X,
X = \frac{220 mg . 126580 mg}{353420 mg}
X = 78.79 mg

For PPh₃:
\frac{353420 mg of Phosphonium is formed by reacting}{220 mg of Phosphonium will be formed by} = \frac{262290 g of PPh3}{X}

Solving for X,
X = \frac{220 mg . 262290 mg}{353420 mg}
X = 163.27 mg

Now
, Assuming these values as for 95 % conversion, we can calculate 100 % yield as follow,

when   \frac{95 percent}{100 percent} = \frac{220 g}{X}
Solving for X,

X = \frac{220 . 100}{95} = 231.57 mg

Now, calculate reactants mass with respect to 231.57 mg
when  \frac{220 mg phosphonium required}{231.57 mg require} = \frac{78.79 g of benzyl chloride}{X}
Solving for ,

X = \frac{231.57 . 78.79}{220} = 82.93 mg of Benzyl chloride

when  \frac{220 mg phosphonium required}{231.57 mg require} = \frac{163.27 g of PPh3}{X}
Solving for ,

X = \frac{231.57 . 163.27}{220} = 171.85 mg of PPh3

So,
reaction was started with reacting 82.93 mg of Benzyl Chloride and 171.85 mg of Triphenyl Phosphine.
