Pure Substances Boil at a Constant Temperature while Mixtures do not, To determine if the Distillate is pure the Liquid distillate would be boiled and for example if the substance is water, it should begin boiling at exactly at 100 degrees celcius if it boils below or above that point it is not a pure substance
What else can I help you with?
How do you determine the substance given the mass?
To determine the substance given the mass, you would need to compare the mass to the known density of various substances. By dividing the mass by the volume (which can be calculated from the dimensions of the object), you can determine the density of the substance. Then, you can compare this density to known values to identify the substance.
Which substance would be most appropriate to determine whether a substance contains simple sugars such as glucose?
Benedict's solution
What is the Volume of 1 lb of?
The volume of 1 lb of a substance would depend on the density of that substance. Without knowing the specific substance and its density, it's not possible to determine the volume.
How would knowing the density of different substances be useful?
it can determine if an object sinks or floats in the substance
What kind of information would need to be collected about a planet in order to determine if humans could survive a visit to its surface?
All of the information.
How could density be used to determine the mass of a particular volume of a substance?
To determine the mass of a particular volume of a substance using density, you would multiply the density of the substance by the volume of the sample. The resulting value would give you the mass of the substance based on the known density and volume relationship (mass = density x volume).
After a hike a group of people had collected samples from many types of flowers what would be most useful to help them determine which species was which?
Dichotomous key
How can you determine the density of a substance?
To determine the density of a substance, you would divide the mass of the substance by its volume. The formula for density is density = mass/volume. Measurements should be taken in units such as grams for mass and cubic centimeters for volume.
What type of indicator should be used to determine the pH of an opaque substance?
Indicators would work to determine the pH of colored substances. The color change may be difficult to read depending on the indicator used. Another alternative to adding a indicator to the substance would be to use a test strip.
How much does a liter of rice weigh?
A litre is a measure of volume not mass. What substance you have a litre of would determine its mass.
How do you determine whether a system is a subs or homogeneous mixt?
A mixture is homogeneous if its composition and properties are uniform throughout. A substance is a subset of mixtures, characterized by having uniform composition only. To determine if a system is a mixture or a substance, you would need to analyze its physical and chemical properties for uniformity.
Why would a urine culture be needed?
A sterile container must be used to collect a urine culture for many reasons. The sample collected cannot be tainted with any substance that is being tested for.
