What is a homegenous mixture?
A homogeneous mixture is a mixture where the components are uniformly distributed throughout the mixture, creating a uniform composition. This means that any sample taken from the mixture will have the same properties and characteristics as any other sample. Examples of homogeneous mixtures include air and saltwater.
Why would the mass of a sample containing calcium get larger after a reaction?
The mass of a sample containing calcium might get larger after a reaction due to the calcium reacting with elements or compounds in the environment to form new substances that add weight to the sample. This could include the addition of oxygen, sulfur, or other elements to the calcium during the reaction.
How does atomic absorption spectroscopy work to analyze the concentration of elements in a sample?
Atomic absorption spectroscopy works by passing a light beam through a sample containing the element of interest. The atoms in the sample absorb specific wavelengths of light, which are then measured to determine the concentration of the element in the sample.
Which will freeze faster pure water or or a mixture?
Pure water will freeze at a higher temperature than a mixture containing water. Therefore, if a means for extracting energy from a sample of pure water is the same as a means for extracting energy from a sample of a mixture containing water, the pure water will freeze first.
Briefly explainthe meaning of the phrase resolve a mixture of compounds?
Resolving a mixture of compounds refers to the separation or purification of different substances within a mixture. This process is often done using techniques like chromatography or distillation to isolate individual compounds based on their physical or chemical properties.

Why is popcorn a mixture?
Because it contains more than one elements, and the mass ratios among its elements are not constant from one sample of popcorn to another.
Is carbon monoxide an element or a compound mixture?
Pure carbon monoxide is a compound, containing equal numbers of carbon and oxygen atoms in any sample of the compound.

How do you make a pure sample of Iodine?
To make a pure sample of iodine, you can start with a mixture containing iodine and other substances, then use a process like sublimation to separate the iodine from the other components. Sublimation involves heating the mixture to allow the iodine to vaporize and then cooling it to condense the iodine back into solid form. This process helps to obtain a pure sample of iodine.
How do you find the sample mean?
Add the values of the variable for all elements in the sample and divide by the number of elements on the sample.
Which will freeze faster pure water or or a mixture?
Pure water will freeze at a higher temperature than a mixture containing water. Therefore, if a means for extracting energy from a sample of pure water is the same as a means for extracting energy from a sample of a mixture containing water, the pure water will freeze first.
What the two type of mixtures?
Heterogenous and Homogenous mixtures. Homogenous mixtures are uniform in appearance. Sea water is a mixture containing primarily Sodium Chloride and water. If you take a sample of this mixture, you will see that the salt fully dissolves in water and the sample is uniform in appearance. Heterogenous mixtures non-uniform. You can see the components of the mixture. An Example is a mixture of oil and water. Oil does not dissolve in water and forms a separate layer above water.
Now you need the latest and greatest dockers commercial song it has a lyric containing California gold you think?
"California Soul" by Marlena Shaw - the sample you hear during the Dockers commercial is the best part of the song (the rest is good too).
Sample of a substance containing copper?
copper oxide...
A typical soil sample is an example of a homogeneous mixture?
No, a typical soil sample is heterogeneous.
