What solvent would you use to determine the density of magnesium nitrate?
To determine the density, you need to know the volume of a known mass of substance. To find the mass, just weigh out a sample. To determine the volume of a sample, a common method is to put some liquid in a graduated cylinder and record the volume. Then add the weighed sample (in this case MgNO3), and then record the new volume. Subtract the original volume from the new one, and the difference is the volume of the solid. To do this, accurately, the solid must be completely insoluble in the liquid. And so the liquid should not really be a solvent at all! For an ionic compound MgNO3, using a non-polar organic solvent (such as hexane) should ensure essentially zero solubility.
What is the manipulative variable of the separation of ammonium chloride sodium chloride and sand HELP?
The manipulative variable in the separation of ammonium chloride, sodium chloride, and sand could be the choice of solvent used for extraction. For example, you could manipulate whether to use water, acid, or another solvent to dissolve the ammonium chloride. This variable would directly affect the separation process and outcome.
How many moles of of aluminum chloride could be produced from 29.0 g of aluminum?
To determine the moles of aluminum chloride produced, you need to use the balanced chemical equation. If aluminum reacts with chlorine to form aluminum chloride, the molar ratio is 2:3. First, determine the moles of aluminum using its molar mass, then use the molar ratio to find the moles of aluminum chloride that could be produced.
Which is good solvent mix in acetone?
A good solvent mix with acetone could include water or ethanol, as they are miscible with acetone and can help enhance its solubility for certain compounds. It is important to consider the specific properties and compatibility of the substances you are working with to determine the best solvent mix for your needs.
How might a scientist distinguish the compounds stronium chloride and patassium chloride?
They are both fine white powder type crystals with high Mp's so I would go with density or molar mass. The molar mass of strontium chloride is 158.53 (anhydrous, and up to 266.62g/mol at it's most hydrated) and of potassium chloride is 74.55g/mol. You could so a density test but for that you must make sure to use the anhydrous form. I believe the density of strontium chloride is 3.05g/cm3 (when it is anhydrous) and potassium chloride is 1.98g/cm3. The problem with this is if stontium chloride's density can be recorded as low as 1.93 depending on how hydrated it is so in order to this accuratedly you must use the anhydrous form.

How could you determine the density of a king's crown?
water displacement
How could you find the density of water?
density = mass/volume Determine the mass and volume of the water, and then divide the mass by the volume, and that will give you the density.
Is cocoa butter a solute?
no, its a compound ANS2: It could be a solute or it could be a solvent. You will need to determine if it is being dissolved (solute) into something or is having something dissolved into it (solvent). The rule is: that which is in greater concentration is the solvent. If it is a 50:50 mixture there is no need to fuss about the distinction.

How could density be used to determine the mass of particular volume of a substance?
In a set volume of any substance increasing the density increases its mass
What property could he easily measure in the lab to help him determine whether the metal is pure zinc?
One property he could measure is the density of the metal. Pure zinc has a specific density, so comparing the measured density to the known value for pure zinc can help determine the metal's purity. He could also perform a chemical test, such as reacting the metal with acid to see if it produces characteristic reactions of zinc.
How do you figure out the weight of a rock?
You could weigh it. You can also determine its density by comparing it to an equal volume of water, but first you would have to determine how much water it displaces to determine its volume.

A good solvent mix with acetone could include water or ethanol, as they are miscible with acetone and can help enhance its solubility for certain compounds. It is important to consider the specific properties and compatibility of the substances you are working with to determine the best solvent mix for your needs.
How could you separate dichlorobenzene from silicon dioxide?
One way to separate dichlorobenzene from silicon dioxide is to use a solvent extraction method, where dichlorobenzene can dissolve in a solvent like ethanol, while silicon dioxide remains insoluble. After mixing the mixture with ethanol, the solution can be filtered to separate the solid silicon dioxide from the solvent containing dichlorobenzene. The solvent can then be evaporated to isolate the pure dichlorobenzene.
Which substance represented in Figure 2.1 (A or B) is solvent?
Without access to Figure 2.1, I cannot definitively identify which substance is the solvent. Typically, in a solution, the solvent is the component present in the greater amount and is usually the substance that dissolves the solute. If you provide more context or details about the substances labeled A and B, I could help you determine which one is the solvent.
