How does changing the amount of one substance affect a mixture identity and compounds identity?
The compounds identity remain unchanged; but the new mixture is different.
Do properties remain the same regardless of the amount of the substance?
Yes, properties such as density, boiling point, and melting point remain constant regardless of the amount of a substance. These properties are intrinsic to the substance and do not change based on the quantity present.
How Does the total amount of matter in a substance increase decrease or stay the same after a chemical or physical change?
The total amount of matter in a substance remains the same after both chemical and physical changes. This is known as the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction or physical change, only rearranged. So, the total mass of the substances before and after the change will be equal.
Is sand added to water a mixture or pure substance?
Sand added to water is a mixture. Sand is a solid substance composed of tiny particles, while water is a liquid. When sand is added to water, it does not undergo a chemical change and can be separated back into its original components.
What term describes how much energy it takes to change the temperature of the substance?
specific heat capacity
Combination of substance in which neither substance change?
mixture
How does changing the amount of one substance affect a mixture identity and compounds identity?
The compounds identity remain unchanged; but the new mixture is different.
Is mixing a chemial change?
By definition, a mixture is two or more substances that are physically combined. In a chemical change, the substance interacts with another substance and undergoes a chemical change. So, no, a mixture is not a chemical change.
Is separate is a physical or chemical change?
when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.
How can a mixture be separated in a chemical change?
A chemical change involves the formation of new substances, making it challenging to separate a mixture. The substances in a mixture undergo a chemical reaction, forming new compounds with different properties. Separation of these compounds typically requires additional chemical reactions or processes.
Is it true that the properties of a substance change when it is added to a mixture?
yes.true
When a substance is in an mixture what does each substance keep?
In a mixture, each substance retains its own physical and chemical properties. This means that the individual components do not change or combine with each other; they simply coexist together in the mixture.
What change when the amount of a substance change?
total thermal energy
Does the amount of substance change its thermal energy?
No, the amount of substance does not change its thermal energy. Thermal energy is dependent on temperature and the specific heat capacity of the substance, not on the amount of the substance.
What happens to the density of a given substance if you increase the amount of substance that you have?
The density of a substance remains constant regardless of the amount of the substance. Density is an intrinsic property of a material and is determined by its mass and volume. Increasing the amount of substance will only change the mass and volume proportionally, thus keeping the density constant.
How do you change the concentration of a substance?
To change the concentration of a substance, you can either add more of the substance (to increase concentration) or dilute it by adding more solvent (to decrease concentration). The concentration is typically measured as the amount of solute divided by the total volume of the solution.
Do properties remain the same regardless of the amount of the substance?
Yes, properties such as density, boiling point, and melting point remain constant regardless of the amount of a substance. These properties are intrinsic to the substance and do not change based on the quantity present.
