Would the oils and sweat make a homogeneous mixture or a heterogeneous mixture Explain your answer?
Oils and sweat would form a heterogeneous mixture because they are immiscible, meaning they do not dissolve into each other. The oils would float on the sweat, creating distinct layers within the mixture.
Why is the mixture placed above the level of the solvent in chromatography?
Placing the mixture above the solvent level in chromatography allows the solvent to travel up the stationary phase through capillary action, carrying the components of the mixture at different rates based on their interactions with the stationary phase. This separation process helps to distinguish and isolate the different components of the mixture.
What happens if the mixture when heated?
When a mixture is heated, the individual components may react differently based on their physical and chemical properties. Some components may evaporate, others may change state, and some may undergo chemical reactions. The outcome would depend on the specific mixture being heated.
Is table sugar added to a cup of coffee and stirred a pure substance or a mixture?
The coffee with added table sugar would be considered a mixture. The table sugar dissolves in the coffee, creating a homogeneous mixture where the sugar molecules are evenly distributed throughout the coffee.
Is gravel and H20 a mixture or solution?
Gravel and H2O (water) would be considered a mixture. Gravel does not dissolve in water, so the two substances would remain physically separate in the container.

What would be observed from an aqueous mixture of magnesium chloride and sodium hydroxide?
You would observe precipitation of magnesium hydroxide.

Oils and sweat would form a heterogeneous mixture because they are immiscible, meaning they do not dissolve into each other. The oils would float on the sweat, creating distinct layers within the mixture.
Would a mixture of lipids and proteins be considered alive based on the attributes of life?
No, however they would be considered ediable by the attributes of lunch
What would you use to observe the stars?
To observe the stars, you would use a telescope.
What prefix from spectator would define see?
The prefix in "spectator" that defines the action of seeing is "spect-". This prefix comes from the Latin word "spectare," which means "to see" or "to watch."
What properties would you observe when you use a metric ruler?
You would observe the length of objects.
What makes an icing a colloid?
Ice cream is a nontransparent, homogeneous mixture that will not settle out or separate into layers based upon the physical properties of the substances in the mixture.
Process would be most appropriate to separate a mixture?
One appropriate process to separate a mixture is chromatography. In chromatography, the mixture is dissolved in a solvent and then passed through a stationary phase where components separate based on their affinity for the stationary phase. This allows for the individual components of the mixture to be identified and collected.
Would a mixture of protein and nucleic acids be considered alive?
No. It's sometimes hard to define life, but it must be able to reproduce and to use energy. An unorganized mixture could not do that, to my knowledge. Origin of life questions are harder to answer.
