How do you purify a substance?
You can purify a substance using methods such as filtration, distillation, crystallization, or chromatography. These techniques separate impurities from the desired substance based on different physical or chemical properties.
Would it be possible for two pure substances to have exactly the same set of properties?
Not if they are solid substances (ie one is not hollow in the middle). That was how Archamedies worked out how to prove the gold crown was pure gold. The density of every substance (mass per unit volume) is unique. * * * * * Not so sure about the density of EVERY substance being different. Every PURE substance: probably yeas. But every substance? For example, the density of steel can be varied from 7.75 gcm-3 to 8.05 gcm-3, by varying the proportion of the other materials in the alloy. Presumably there are some other substances with a density in that range.
Can you get the same substance back after a chemical reaction?
No, a chemical reaction involves the rearrangement of atoms to form new substances with different properties. It is not possible to retrieve the original substance once it has undergone a chemical reaction.
How are leaf classified?
They are classified like underwear in a shoe box. THEY CANT BE CLASSIFIED IT CANT BE POSSIBLE! So how about you make a banana split and put some Nachos in it then build a snowman.
What property of a substance does the change in temperature indicate?
Change in temperature directly indicates a change in the mean amount of kinetic energy possessed by each particle. It also indirectly indicates a possible change in state, and a possible change in chemical properties too (chemical reactions often involve energy transfer in the form of temperature change).
What is the substance of classified as compound?
A compound is defined as a substance that contains at least two chemical elements and always has a constant mass ratio between elements for each possible pair of the elements that are present in it.
How do you purify a substance?
You can purify a substance using methods such as filtration, distillation, crystallization, or chromatography. These techniques separate impurities from the desired substance based on different physical or chemical properties.
How to write a sentence on properties in science?
Properties of a substance refer to its characteristics, both physical and chemical. By characteristics we refer to its combination with other elements and what new substance is formed with this mixture. Properties also refer to density, temperature, odour, taste (when possible to check it out) Sincerely confessing I do not understand anything about properties in science. Experts, please, help me. Thanks.
Is it possible to rotate a sphere of a size of namely tennis ball made of substance having magnetic properties but without touching it?
yes it is possible. if we take a magnet and get close to the ball having magnetic properties but not too close (if too close it will stick together) we can make the ball to rotate.
Is ununoctium a metal nonmetal or metalloid?
Ununoctium is considered a nonmetal. Ununoctium is supposed to be a noble gas.
Compare the results if you divided iron and water each into the smallest substance possible?
The smallest substance of Iron is itself (Fe) The smallest substance of water (H2O) is Hydrogen (H) and Oxygen (O) Compared results are Water having 1 more element than Iron. 2 elements are derived from water and only 1 from Iron.
Is it possible for the specific heat of a substance to have a negative value?
No, it is not possible for the specific heat of a substance to have a negative value.
Is it possible for a molecule to exhibit both chiral and achiral properties, resulting in it being classified as a meso compound?
Yes, it is possible for a molecule to exhibit both chiral and achiral properties, making it a meso compound. Meso compounds have chiral centers but also possess a plane of symmetry, which results in them being optically inactive despite having chiral elements.
What effect does observing a substance physical property have on the substance?
Physical Properties: The physical properties of a substance are those permanent properties which describe the physical characteristics of the material. Observation where possible, has no effect on the physical characteristic of the material.
Can knowing about chemical properties can help identify elements and compounds?
Yes, knowing about chemical properties can help identify elements and compounds because each element and compound has unique chemical properties that can be used for identification. Properties such as melting point, boiling point, density, and reactivity can be used to differentiate between different substances. By comparing the observed properties of an unknown substance to known properties, it is possible to determine its identity.
Can a substance be classified as ionic or molecular based only on its solubility in water?
Not always. While many ionic compounds are soluble in water, some molecular substances can also be soluble depending on their polarity and intermolecular forces. It is important to consider the chemical structure and properties of the substance in addition to its solubility in water when determining if it is ionic or molecular.
How intensive extensive properties are interchangeable?
not possible
