Are naturally occurring materials pure substances. explain?
Most naturally occurring materials are not pure substances as they often contain mixtures of different compounds or elements. For example, minerals, rocks, and soils are composed of various elements and compounds, making them impure. Pure substances are rare in nature and are typically only found in the form of elements (like gold or silver) or compounds with a specific chemical composition (like water or salt crystals).
Explain the following weight approximately 5 grams of NaCl to the nearest milligram?
5 grams of NaCl, or table salt, is equal to 5,000 milligrams. to convert grams to milligrams you simply multiply by 1,000.
Explain whether water is a cause of either chemical weathering physical weathering or both?
Water can cause both chemical and physical weathering. In chemical weathering, water can react with minerals in rocks to break them down into new substances. In physical weathering, water can seep into cracks in rocks, freeze, and expand, creating pressure that breaks the rock apart.
Explain how you can tell whether a chemical reaction has taken place?
A chemical change or reaction happens if new substances are formed. there may be a change in temperature so the reaction mixture may heat up or cool down. it also might change colour, give off bubbles of gas or fumes and you also might hear fizzing or a gas might explode.
What do plate tectonics help explain?
Plate tectonics help explain the movement of Earth's crustal plates and how they interact at plate boundaries to create features such as mountains, earthquakes, and volcanoes. It also helps to understand the distribution of earthquakes and volcanic activity around the world.
How do you explain the phrase like dissolves like in terms of polar and nonpolar substances?
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
Explain why nonpolar substances generally do not dissolve in polar solvents?
Nonpolar substances are not attracted to the polar molecules in the solvent due to differences in their electrical charges. This results in weak intermolecular forces between the nonpolar substance and the polar solvent, making dissolution less likely. Thus, nonpolar substances tend to remain clustered together rather than dispersing in the polar solvent.
What examples of dipole induced dipole forces?
An example of dipole-induced dipole forces is the interaction between a polar molecule, such as water, and a nonpolar molecule, such as nitrogen. The polar molecule induces a temporary dipole in the nonpolar molecule, creating an attractive force between the two molecules. This type of interaction helps explain why some substances can dissolve in water even if they are nonpolar.
Explain the statement like dissolves like?
Oh, dude, it's like this: "like dissolves like" is just a fancy way of saying that polar substances mix well with other polar substances, and nonpolar substances mix well with other nonpolar substances. It's basically like how introverts hang out with introverts and extroverts hang out with extroverts. So, if you want your substances to get along and mix nicely, just remember: like attracts like!
Explain why ethanol will dissolve in water and carbon tetrachloride will not?
Ethanol is a polar molecule because of the hydroxyl group (CH3CH2-OH). Carbon tetrachloride (C-CL4) is non-polar and does not exhibit hydrogen bonding. Many organic compounds are water soluble because of their polar nature i.e. acetone, citric acid, and others.
Explain how a solute can dissolve in polar and nonpolar solvents?
=a polar solvent dissolves a polar solute, and nonpolar solvents dissolve nonpolar solutes. likes dissolve likes=
Could somebody explain the phrase like dissolves like?
This means that substances are more likely to dissolve in other substances with similar chemical properties. It is most often used when discussing polar and nonpolar solvents. For example, oil will not dissolve in water because oil is nonpolar and water is polar. Basically, a polar solvent will generally dissolve polar solutes and sometimes ionic solutes, and a nonpolar solvent will generally dissolve nonpolar solutes.
Were there any nonpolar compounds that had polar covalent bonds If so which ones Explain this apparent this inconsistency?
CBr4 and SO3 have polar covalent bonds, yet they are nonpolar compounds. The shape of each molecule enables the charges to be distributed evenly, rather than being concentrated in one area. As a result, the molecule as a whole is nonpolar.
How does principle of like dissolves like explain the differing solubilities of solutes in various solvent?
The principle of "like dissolves like" states that substances with similar polarity and intermolecular forces are more likely to dissolve in each other. For example, polar solutes dissolve better in polar solvents, while nonpolar solutes dissolve better in nonpolar solvents. This is because molecules with similar interactions can more easily mix at a molecular level, increasing solubility.
Explain the phrase like dissolves like and give an example of two like substances?
In chemistry, the term like dissolves like refers to the fact that similar type solutes will dissolve in solvents that have a similar type of chemical composition. Substances like water, acetone, and alcohol are polar molecules and so are soluble in each other. Substances that form non-polar molecules like oil and gasoline are soluble in each other. However, oil will not dissolve in water because of their different chemical bonds.
How does the principle of like dissolves like explain the differing solubilities of solutes in various solvents?
Generally polar solutes are dissolved in polar solvents and nonpolar solutes are dissolved in nonpolar solvents.
How does the principle like dissolves like explain the differing solubilities of solutes in various solvents?
Generally polar solutes are dissolved in polar solvents and nonpolar solutes are dissolved in nonpolar solvents.
