What else can I help you with?
Do you agree that all homogeneous matter can be classified as pure substance?
Yes, all homogeneous matter can be classified as a pure substance because it has a uniform composition throughout. This means that all samples of the matter have the same properties and composition, making it a pure substance.
The density of a substance is the same for all samples of the substances?
Density is simply the mass divided by volume. This means that it is the amount of the substance in a specific unit of space. Because a pure substance indicates that it is exactly that, a substance made of a specific combination of elements, it will always have the same density because those elements can only take one form in order for it to be pure.
Should the density of Al be the same for all Al samples?
The density of pure aluminium is the same for all samples.
How can you use Dalton's atomic theory to explain why every sample of pure substance has the same properties?
Dalton's atomic theory states that elements consist of indivisible particles called atoms and that atoms of the same element are identical in size, mass, and properties. Therefore, every sample of a pure substance will have the same properties because each sample is made up of the same type of atoms arranged in the same way.
Can the chemical properties of a substance be observed without changing the substance?
physical properties
The density of the substance is the same for all samples of the substance true or false?
Any sample size of a particular substance will have the same density.
Is it true that the density of a substance is the same for all samples of the substance?
Yes, density is an intrinsic property of a substance and remains constant regardless of the sample size or quantity. The formula for density is density = mass/volume, and this relationship holds true for all samples of the same substance.
Is The density of a substance is the same for all samples of the substance?
Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
Why are all samples of a given substance have the same intensive properties?
The properties of a pure substance do not vary from sample to sample because there is no reason for them to. Why would they? Water is water, and if you take any sample of water from any stream, lake or ocean and remove all the "stuff" in it to leave only the water, all the samples will behave the same way physically and chemically. The chemical properties of a substance (and the physical ones, too) are set by what the substance is. And these properties define the way the substance behaves in the universe as a whole. There is no reason for any water found on, say Mars, to behave any differently than any water here on Earth - or anywhere else in the universe.
True or false the density of a substance is the same for all samples of substance?
False. The density of a substance can vary depending on factors such as temperature and pressure. Additionally, impurities in a sample can also affect its density.
Do you agree that all homogeneous matter can be classified as pure substance?
Yes, all homogeneous matter can be classified as a pure substance because it has a uniform composition throughout. This means that all samples of the matter have the same properties and composition, making it a pure substance.
Do all samples of a substance have different physical properties?
Yes, two substances can have the same physical property. For example, both water and ethanol are clear. For this reason, multiple properties must be examined when determining the identity of a substance.
Is the density of a substance varies with samples of that substance true or false?
i think that the answer is False because they have nothing to do with each other

Which is more dense 1 mL of water or 50 L of water?
The answer is: No. Density is a property of a substance, and doesn't depend on the size of the sample. Samples of different sizes all have the same density, as long as they're all samples of the same substance, their compositions are all the same, and the conditions are the same in every case. (Samples of ice and water have different density, because the conditions are different.)
Are all voluntary samples bad samples?
No
