Would it be possible for two pure substances to have exactly the same set of properties?

Not if they are solid substances (ie one is not hollow in the middle). That was how Archamedies worked out how to prove the gold crown was pure gold. The density of every substance (mass per unit volume) is unique.

Not so sure about the density of EVERY substance being different. Every PURE substance: probably yeas. But every substance? For example, the density of steel can be varied from 7.75 gcm-3 to 8.05 gcm-3, by varying the proportion of the other materials in the alloy. Presumably there are some other substances with a density in that range.

You have two solid substances that look the same What measurements would you take and which tests would you perform to determine whether they actually are the same?
- chemical analysis of these substances - determination of some physical properties
What would happen if the membrane of the nucleuos became permeable to most substances?
That would expose the DNA to possible damage.
What is the total of original and new substances that are the same after a chemical change?
It would be called a physical change, and would not be a chemical change at all. In order for a chemical change to occur, the original substances (reactants) must have different physical and chemical properties than the new substances (products).
Is a reaction with many substances a physical property of water?
No, a reaction with many substances is not a physical property of water. Physical properties of water include its boiling point, density, and color, whereas the ability to undergo reactions with different substances is a chemical property.
How would changing proportions of substances in an alloy change its properties?
Changing the proportions of substances in an alloy will change the physical properties of that alloy. The differing substances will change the metallic structure of the crystals of the metal alloy, and this alters the ductility, durability, hardness, tensile strength, toughness and other characteristics we assess are regards alloys.
When two substances combine chemically the properties of the products of what?
I take this to be what the properties of the new substance would be. That depends on what the two original substances were.
What is the smallest particle of a substances that has all the properties of the substances?
For an element, it would be an atom. For a molecular substance, it would be a molecule. If it is an ionic compound, it would be a formula unit.
I found a brown snake with a tinge of green on the end Can you tell me what snake this is?
No exactly no I would have to see the snake first, but it could be possible to be a grass snake No exactly no I would have to see the snake first, but it could be possible to be a grass snake No exactly no I would have to see the snake first, but it could be possible to be a grass snake No exactly no I would have to see the snake first, but it could be possible to be a grass snake No exactly no I would have to see the snake first, but it could be possible to be a grass snake No exactly no I would have to see the snake first, but it could be possible to be a grass snake No exactly no I would have to see the snake first, but it could be possible to be a grass snake

How will you use the properties of an element to discover its identity?
each object has certain properties so it would be easy to find its identity if you found out exactly what was in it
What is the substance that cannot be broken down into simpler substances with different properties?
I believe that would be an element. What is the context of your question?

The traits of substances that can be observed or measured without changing their chemical identity?
The traits of those substances would be physical traits, also known as physical properties.
Acids are substances that?
Acidic substances, also known as acids, are quite numerous; some well known examples include nitric acid, hydrochloric acid, and sulfuric acid. Vinegar, orange juice, and Coca Cola are also acidic.
What would happen if the membrane of the nucleuos became permeable to most substances?
That would expose the DNA to possible damage.
I Need to separate two substances in a compound how would you seaparared?
There are several methods to separate substances in a compound, depending on their properties. Some common methods include distillation (for separating liquids with different boiling points), filtration (for separating solids from liquids), and chromatography (for separating substances based on their differing properties). The choice of method depends on the specific substances and their physical or chemical characteristics.
