In the real world, tap water is heterogeneous. If you've ever noticed the bubbles in the water or the occasional speck of calcium carbonate that flakes off the walls of the Plumbing, you can make that argument.
If you are attending a US public school and you are trying to argue that point with your science teacher, who probably doesn't have the time to consider divergent opinions and is basing the correct answer from a textbook, you should probably bite your tongue and say "homogeneous".
Add: Tap water that comes from the water treatment plant is homogeneous. It is possible that particulate contaminants could taint the water as it flows from the plant to your house. The bubbles are formed when the water passes through the screen at the end of the faucet, which increases oxygenation of the water, and supposedly improves the taste. If flakes of calcium carbonate or any other substance lining the pipes is breaking off and getting into your drinking water, you should consider a filter for you faucet, or even your whole house, and even having your plumbing redone.
When a fluid is clear it is a homogenous mixture or pure.
No.If it's "pure" it's not a mixture.
Platinum (Pl) is not a mixture. It is an element. It consists only of itself.
Pure water (H2O) is a chemical compound; if the water is impure may be a homogeneous or heterogeneous mixture.
It is a homogenous mixture.
It is a pure compound, not a mixture at all.
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
Vodka is a homogenous mixture; it consists of water, alcohol, and a few other things.
When a fluid is clear it is a homogenous mixture or pure.
A pure substance is a substance that has only that substance in it. One kind of molecule or atom. A homogenous mixture can have different molecules and/or atoms in it, but they have to be in the same physical state. Water mixed with honey would be a homogenous mixture, because they are both liquids. Water mixed with sand would be heterogeneous.
Helium is an element which makes it a pure substance.
Yes. Pure air is a homogenous mixture. Air is a mixture of various kinds of gases. A mixture is said to be homogenous when all its constituents are in phase. Example, a mixture of water & milk is a homogenous mixture, as water & milk both are liquids & are in phase. Same is the case with pure air. All the constituents gases of pure air are in phase with each other. Hence its a homogenous mixture.
it is heterogeneous because the pepper does not dissolve in the water
d) a heterogeneous mixture
No.If it's "pure" it's not a mixture.
It's a compound. H2O - Two hydrogen atoms, one oxygen atom Water is a compound as it can be reduced to simpler elements (Oxygen and water).It is a homogenous mixture("the same") as it is uniform throughout. E.g: Salt and sand mixed together would be a heterogenous mixture("different") as you can distinguish between sand and salt. A pure 'mixture' is usually homogenous, especially liquids.
Platinum (Pl) is not a mixture. It is an element. It consists only of itself.
