Can universal indicator be used to determine the strength of acids and bases?
No, it can only show whether the substance is an acid or a base.
How could you determine whether a white powder was zinc sulfide or silver nitrate using hydrochloric acid solution?
To determine what the white substance is we must add it to HCl.
How do you determine whether a substance is soluble?
The simplest and most obvious would be to dissolve the test substance in the other. If the first is completely miscible in the second and seen not to form separate layers or bubbles, etc., then it is soluble.
What properties of substances can you observe and how do these properties determine the usefulness or hazards of a substance?
You can observe physical, chemical, and characteristic properties of a substance and can be used to determine the usefulness of a substance by, giving us information about the substance usually using our 5 senses which are physical properties. Or being able to describe the substances ability to undergo changes to its composition to produce one or more new substances, chemical property. Or even just being able to identify whether or not the substance is pure or not can help us determine if the substance is hazardous or not. two other properties I did not mention were the qualitative and the quantitative properties.
How can you determine experimentally whether or not a substance is present in ionic or molecular form when in aqueous solution?
If the solution will conduct electricity it is ionic. Solutions made from molecules do not conduct electricity.

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.)
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.
Which substance would be most appropriate to determine whether a substance contains simple sugars such as glucose?

What things could be used to determine whether a substance is an acid or a base?

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 are some limitations of using heating to determine whether the substance is an element or a compound?
limitation of heating element
Can universal indicator be used to determine the strength of acids and bases?
No, it can only show whether the substance is an acid or a base.
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).
Why is tasting or feeling an unknown solution not good way to determine whether the solution is acidic or alkaline?
This solution may be toxic, corrosive or radioactive.
