How is a chemical change different from a physical change?
a physical change can be reversed a chemical one can'tA chemical change is when a new substance, with new and different properties, is produced. The identity of the original substance is changed. In contrast, a physical change is when one or more of a substance's physical properties have simply been altered; no new substance is produced.
Why is important to organize the elements in a periodic table?
It is helpful to organize things by characteristics because you can tell that certain elements are similar. For example if you knew nothing about the chemical or physical properties of (Rb) Rubidium, you could guess it has properties similar to (Cs) Cesium since they are in the same group. The common "Periodic Table" has many interesting forms. Search: "periodic table"
When is diffraction helpful?
Diffraction is helpful in various fields such as physics, chemistry, and crystallography for studying the structure and properties of materials. It is particularly useful in analyzing the atomic and molecular structure of solids, liquids, and gases, as well as in techniques like X-ray diffraction for determining crystal structures. diffraction is also used in fields like optics to create patterns and manipulate light.
What factors should be considered to determine whether ou have enough time to read an assignment?
To determine if you have enough time to read an assignment, consider factors such as the length of the assignment, your reading speed, your comprehension level, any distractions or interruptions, and your current schedule and workload. It may also be helpful to assess your familiarity with the topic and whether you need to take notes or study the material in more depth.
Wendy wants to know which colors of light are emitted by her flashlight. Which tool could help her?
A spectrophotometer would be helpful for Wendy to determine the colors of light emitted by her flashlight. This device can separate light into its different wavelengths and identify the specific colors present.
Are physical and chemical properties of rocks helpful to determine the type of rock?
They are the only way to determine a rock type.
How is knowing the properties of liquids helpful?
Knowing the properties of fuel is very helpful. For eg, if we know its burning temperature and amount of calories produced, we can determine its efficiency to be used as a fuel. also by knowing the properties of viscosity we can determine its rate of flow, how to efficiently use it for the various purposes. Properties help to determine the best use of the liquid and thus increasing efficiency and productivity.
What physical properties are most helpful when identifing similar objects?
It depends on the objects. the properties that help compare an eyeball to a marble for example, are much different then the properties that are going to be most helpful to compare a car to a truck.
What properties can be used to identify matter?
Many things share properties. I would start with visually comparing (color, physical state, etc.) and odor, then move on to Density, then boiling point and/or melting point, and then continue on in this fashion until I know for sure that this can be no other substance than the one I'm looking for. A pH test is sometimes helpful for liquids. Certain metals burn different colors, which can also be helpful. Solubility tests are normally helpful as well.
Why is it helpful to know the the physical and chemical properties of a substance?
In is impossible to work with materials, substances etc. without a deep knowledge of all chemical and physical properties. And all around us: foods, building materials, electronics, cars, drugs are composed from materials with specific properties.
Why are characteristic properties helpful in identifying an unknown substance?
melting point.
Where can you find a psychosomatic test?
A physician typically administers a psychosomatic test to determine if the illness or symptoms described are physical or mental in nature. However, there are different books available in the library and online that can be helpful.

What information does the IRS require on 1099 forms?
Determine whether 600.00 has been paid in rental properties. Determine whether 10.00 has been paid in royalties. Determine current level of life insurance. Here is a helpful website. http://www.irs.gov/Businesses/Small-Businesses-&-Self-Employed/Forms-and-Associated-Taxes-for-Independent-Contractors
Does a tweezers help to separate a mixture?
Yes, tweezers can be used to separate a mixture based on the physical properties of the components. Tweezers can be helpful when dealing with larger particles or when finer control is needed in the separation process.
What are the properties of a beaker?
There are several properties that could help a person identify a beaker full of mysterious clear liquid. For example, smelling the liquid might help. Also, seeing what it reacts with, and where it falls on the pH scale would be helpful.
Why is it helpful to have a compass rose on a map?
A compass rose on a map indicates the direction of north, which helps the user orient themselves and determine the cardinal directions. This is important for navigation and understanding the layout of the map in relation to physical landmarks or destinations.
