What characteristics determine whether a substance is flammable?
The main characteristics that determine whether a substance is flammable are its ability to ignite easily and burn rapidly when exposed to heat, oxygen, or a spark. Flammable substances typically have low flash points and release flammable vapors.
Is yellow acid or alkali?
Yellow is not a definitive indicator of whether a substance is an acid or an alkali. The color of a substance is not directly related to its pH or acidity levels. pH testing is required to determine if a substance is acidic or alkaline.
What would be the best way to identify whether or not an unknown substance is made of a certain element?
One way to identify if an unknown substance is made of a certain element is to perform a chemical analysis, such as spectroscopy or mass spectrometry, to determine the elemental composition. Another method is to use techniques like X-ray diffraction to analyze the crystal structure, which can provide information about the type of elements present in the substance.
A substance that is used to determine an acid or base is called?
An indicator is a substance that is used to determine whether a solution is acidic or basic by changing color based on the pH of the solution. Examples of indicators include litmus paper, phenolphthalein, and bromothymol blue.
How can one determine whether a substance is a strong or weak acid?
One can determine whether a substance is a strong or weak acid by looking at its ability to fully dissociate in water. Strong acids completely dissociate into ions in water, while weak acids only partially dissociate. This can be measured by looking at the pH level of the solution - strong acids have a lower pH than weak acids.

What exactly is a reagent in English?
A reagent is a chemical substance that reacts with some other substance. It is common to add a specific reagent to an unknown substance to determine whether or not the substance that the particular reagent reacts to is present. (For example, add a reagent for sugar to test for the presence of sugar.)
Is white crystalline solid a compound or an element?
A white crystalline solid can be either a compound or an element. It depends on the specific substance in question. For example, table salt (sodium chloride) is a white crystalline compound, while pure elemental sulfur can also be a white crystalline solid. Testing and analysis are usually needed to determine whether the solid is a compound or an element.
Which substance would be most appropriate to determine whether a substance contains simple sugars such as glucose?
Benedict's solution
What 2 factors determine the state of a substance?
The two factors that determine the state of a substance are temperature and pressure. These factors influence whether a substance exists as a solid, liquid, or gas.
What things could be used to determine whether a substance is an acid or a base?
litmus paper.
What characteristics determine whether a substance is flammable?
The main characteristics that determine whether a substance is flammable are its ability to ignite easily and burn rapidly when exposed to heat, oxygen, or a spark. Flammable substances typically have low flash points and release flammable vapors.
What is an experiment that can determine whether a solid white substance is a lipid or a carbohydrate?
Rub the substance on a paper bag, if it leaves a grease stain, it is a Lipid.
What 4 things are used to classify minerals?
Minerals have distinct qualities. To determine if a substance is a mineral, there are four major qualifications. The first is to make sure that there are no carbon compounds in the substance. The second is if the material is completely natural. Third is whether the substance is solid. Fourth is that the substance is crystalline.
How can you determine whether a measured value of a substance represents an extensive property?
Its value will be reduced as the numbers of moles of the materials is reduced
How could a determine whether an unknown substance was a mineral?
A mineral is any chemical compound with a constant chemical composition, which of course is the definition of a "pure substance". In earth science you might be distinguishing between "rock" and "mineral". A mineral is a pure substance. A rock is a mixture of two or more minerals in various proportions. For instance, the rock granite is made up of three minerals: quartz, feldspar and biotite (mica).
