Question

substances X was combined with substance Y. Bubbles were observed and the beaker containing the two substances became colder. Is a mixture formed when the two substances were combined? explain your answer

Answer 1

Explanation:

In simplest terms, a chemical change (or chemical reaction) occurs when two substances are mixed together and transform into a third substance. Not all substances react chemically when mixed together, however. For example, some substances, when mixed together, remain simply a mixture of those two substances.

Answer 2

Substances X was combined with substance Y. Bubbles were observed and the beaker containing the two substances became colder. Is a mixture formed when the two substances were combined.

• When two (or more) chemicals are combined, something happens that changes one (or more) of the original substances. We refer to this as a chemical reaction. Heat, gas formation, and colour alterations are all possible. These kinds of alterations show that a chemical reaction has taken place.
• When two or more chemical substances (elements or compounds) are mixed together, a heterogeneous mixture is one in which the various components are easily distinguishable visually and physically.
• So, Only physical change can result in a mixture being generated. A compound is created when two or more components combine in a predetermined ratio after participating in a chemical reaction. Every molecule has the same physical and chemical characteristics.
• We refer to two liquids as being "immiscible" when they do not mix and instead create layers. Whether or not the liquids mix depends on their chemical makeup.
• When two or more distinct substances physically join, a mixture is produced that can be dispersed back into its constituent parts. When two or more compounds combine to create a new substance that cannot be broken down into its constituent parts, a chemical reaction takes place.
