What else can I help you with?
Why can water dissolves many substanes?
Its a polar molecule.
Is water a good solvent for many substanes?
Yes it's the universal solvent
What are ductile substanes?
Easy to change the shape of without destroying the integrity, like plasticene, lead, gold
Difference between biodegradable non-biodegradable substanes?
Biodegradable can be broken down by the earth naturally, non- biodegradable can not.
What do you all the different substanes that an be seen in a heterogeneous ixture?
All of the different substances that can be seen in a heterogeneous mixture include alloys, solutions, suspensions, and colloids. In chemistry, a mixture is a material system that is made up of two or more different substances.
Does a compound not always retain the properties of the substanes that make it up?
A compound does not always retain the properties of the substances that make it up. The properties of a compound are determined by the arrangement of atoms and the type of chemical bonds present, which can result in new properties not seen in the individual elements.
How can you tell from a chromatogram how many coloured substanes there are in a drink?
From a chromatogram, you can tell the number of colored substances present in a drink by observing the number of distinct peaks or bands. Each peak corresponds to a different colored substance in the sample. Analyzing the retention times of these peaks can help identify and quantify the colored components in the drink.
What happens when you dissolve sugar in water?
The sugar dissolves in water, that is why the water becomes sweet.The sugar and water together forms a sugar solution. The water is called a solvent. Sugar, the substance that dissolves in water is called a solute. Water dissolves many substances. These substanes are said to be soluble in water. The ones that do not dissolve in water are said to be insoluble in water.
What substanes can melt ice the fastest?
A very good substance for melting ice is table salt. This is because salt is highly soluble in water, and, as more NaCl dissolves in the water, the more this impurity will depress the melting point. Because the water's melting point will be depressed, it will start to melt above zero degrees Celsius. (I'm not sure this is the best substance to melt ice, I simply put it here because of its solubility in water; if anyone knows a more soluble salt, then that will probably melt ice better) Sand is also really good to melt ice
Why is water such a good solvent for cells?
Water is a good solvent for cells because of its polar structure, which allows it to interact with and dissolve many different types of molecules, such as ions and polar compounds. The abundance of hydrogen bonding in water also helps in breaking down solutes and facilitating various cellular processes. Additionally, water's high heat capacity and ability to regulate temperature make it critical for maintaining cellular homeostasis.
When sampleX is passed through a filter paper a white residue remains on the paper and a clear liquid passes through When liquid is vaporized another white residue remains Is sample X homogeneous?
No, sample X is not homogeneous. The presence of a white residue on the filter paper and after vaporization indicates that there are different components in the sample that are separating out. Homogeneous substances should appear uniform throughout, without residues or separate phases.
Is aluminum foil homogeneous or heterogeneous?
aluminum foil is made of one element, aluminum. All elements are pure substanes, so that means they are homogenous. compounds are also homogeneous. mixtures are heterogeneous or homogeneous, depends if they are mixed up or the same thoughout (like air, like solutions, or like steel (melted iron and carbon frozen into a solid solution).
