What is two or more substance only physically combined is what?
A mixture is when two or more substances are physically combined but can be separated by physical means, such as filtering or distillation. The substances in a mixture retain their individual properties and do not undergo a chemical reaction.
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 two or more substance are combined and cannot be separated?
When two or more substances are combined and cannot be separated by physical means, they form a mixture. This could be a homogeneous mixture, where the substances are evenly distributed like salt in water, or a heterogeneous mixture, where the substances are unevenly distributed like oil and water. If the substances form a new substance with its own unique properties and characteristics, it is a chemical reaction.
When substances are combined and no reaction occurs?
When substances are combined and no reaction occurs, it means that the substances are not capable of undergoing a chemical reaction with each other. This could be due to factors like the stability of the molecules, the absence of necessary reactants, or the lack of sufficient energy to drive a reaction. In these cases, the substances may simply mix together physically without forming any new chemical bonds.
What is a chemical reaction with two or more substances combined to make a more complex compound?
synthesis

When two substances are combined and new substances are formed?
When two substances combine to form a new substance, it is said that a chemical reaction has occurred. This reaction is a combination reaction, also known as synthesis. The new substance formed may or may not possess the properties of the constituent substances.When the separate substances are elements, a chemical reaction is one that creates chemical bonds, the combined substance being a compound.
Which type of substance can only be separated by a chemical reaction?
A compound can only be separated into its constituent elements by a chemical reaction. In a chemical reaction, the bonds holding the atoms in the compound together are broken, resulting in the formation of new substances.

What are the properties of everyday mixtures?
Everyday mixtures are made up of two or more substances physically combined. They can be separated through physical means such as filtration or evaporation. Mixtures do not undergo a chemical reaction when formed.
How do you determine a chemical change has occurred when two substances are combined?
A chemical change can be determined when two substances are combined by observing if there is a color change, formation of a precipitate, evolution of gas, or change in temperature. Additionally, if the chemical properties of the substances change, such as their reactivity or toxicity, it indicates a chemical reaction has taken place.
What must combined to create a chemical equation?
Reactants and products must be combined to create a chemical equation. Reactants are the starting materials that undergo a chemical reaction, while products are the substances that are formed as a result of the reaction.
How are mixtures formed and separated?
Mixtures are formed when two or more substances are combined physically, without any chemical reaction. They can be separated through methods like filtration, distillation, chromatography, and evaporation, based on the differences in their physical properties such as size, solubility, or boiling point.
If two or more substances are combined what is always created?
When two or more substances are combined, a mixture is always created. In a mixture, the individual components retain their distinct properties and can often be separated by physical means. In some cases, if a chemical reaction occurs, new substances called products may be formed. However, the initial combination itself results in a mixture.
