What do two or more substances form when they come together without forming a new substance?
When two or more substances come together without forming a new substance, they can create a mixture. Mixtures are combinations of substances that retain their individual properties and can be separated through physical means. Examples of mixtures include saltwater and air.
Two or more substances come together without forming a new substance is called what?
Only a mixture: sugar and water, salt and pasta, soil and sand.
Is it true that if a physical change that occurs when a substance changes composition by forming one or more new substances?
No, that statement is incorrect. A physical change does not involve changing the composition of a substance or forming new substances. It only alters the physical state or appearance of a substance without changing its chemical composition. When a substance changes composition and forms new substances, it is considered a chemical change.
Is a compound a substance or a mixture?
A compound is a substance composed of two or more elements chemically bonded together in a fixed ratio. This is in contrast to a mixture, which is a combination of two or more substances that are simply physically mixed together without forming new chemical bonds.
What are the differences between solutions and mixtures?
A *solution* is a mixture of substances that are blended so completely that the mixture looks the same everywhere while a *mixture* is a physical combination of two or more substances that are blended together without forming new substances.
What properties of substance determine how that substance will react when combined with other substances?
Chemical
What occurs when atoms link together in new ways to create a substance different from the original substances?
Chemical reactions take place, where atoms rearrange themselves to form new compounds with unique properties. This process involves breaking and forming new chemical bonds, resulting in the creation of a substance that is different from the original substances involved.
A substance that has high reactivity does what?
A substance with high reactivity readily undergoes chemical reactions with other substances or even with itself, often releasing energy in the process. This high reactivity can lead to the substance easily forming new compounds or decomposing into simpler substances.
When a substance is broken down or combined formingnew substance a has occurred?
A chemical reaction has occurred. In a chemical reaction, the atoms in the substances rearrange to form new substances with different properties than the original substances. This process involves breaking and/or forming chemical bonds.
When you add heat to a combination of substances breaking bonds and forming a new substance the process is called a?
Chemical reaction
When light rays are bent and brought together they are?
Light rays are bent and brought by a refraction.
How does minerals occur?
a mineral occurs from two substances or liquids forming together creating small minerals
