Why can't mixtures be classified as a pure substance?
The properties mix together with the mixture.
What is difference between melting point and drop melting point?
The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.
What is the difference between physical property and chemical property?
The way I remember the difference, is: a physical property is a property that you can observe without changing it (or observe without a chemical reaction). So properties like melting point, boiling point, density, color, hardness are all physical properties. A property like 'reacts with water' could only be observed by performing the reaction to observe the change.
What is the time difference between Mississippi and Virginia?
Virginia is one hour ahead of Mississippi.
How can you tell if a substance has not dissolved?
A substance that has not dissolved will typically remain visible as distinct particles or clumps within the solvent. You may observe sediment at the bottom of the container or floating particles that do not disperse. Additionally, if the solution appears cloudy or opaque rather than clear, this may indicate undissolved material. If you stir the mixture and the particles do not break down or disperse, it confirms that the substance has not dissolved.
Is the difference between a pure substance and a mixture easy to observe?
No.
What is the difference between the words 'examine' and 'test'?
Examine is the same thing as saying observe, or look at. Test means you find out what happens when you combine or add something to an element or mixture.
What did Darwin observe about finches in the Galpagos Islands?
The difference between their beaks
How many sets of properties do you need to observe in order to classify a material as a homogeneous mixture?
To classify a material as a homogeneous mixture, you typically need to observe at least two sets of properties. These properties should indicate that the components of the mixture are uniformly distributed and that there are no visible differences between different parts of the mixture.
Is there a time difference between Houston and Chicago?
No, both observe Central Standard Time.
Why can't mixtures be classified as a pure substance?
The properties mix together with the mixture.
Must a new substance be formed when you observe a chemical property?
Yes , it should or else it is a physical property
What physical substance is what you can observe without changing the substance?
Type your answer here... water

What is the comparison between Rene Descartes' and John Locke's theory of substance?
Descartes had a dualist substance theory and believed that there were two substances, the mind and the body. Locke also believed that there were spiritual substances and physical substances, but his theory of substance relied on the substratum, a characterless thing that contains the characteristics we observe. Since we cannot observe substance, Locke believed we could not know anything about it.
Does new substance's be formed when you observe a chemical property?
no!
Must new substances form when you observe a chemical property?
Yes. If you observe a chemical property, the substance will be undergoing a chemical change, which by definition produces a new substance.
