What else can I help you with?
When sugar is added to water does this make a pure substance or a mixture?
It makes a mixture.
What is the difference between partial molal quantities and partial molar quantities?
During the determination of the partial molal quantities the weight of the solution to which a substance is added is taken into consideration while in case of the partial molar quantity the volume is taken into consideration.
Is cornstarch a chemical or a physical change when vinegar is added?
When vinegar is added to cornstarch, it undergoes a physical change. The vinegar interacts with the cornstarch molecules, causing them to form a non-Newtonian fluid, which changes the physical properties of the mixture.
What has to be added to a substance to cause a phase change?
Adding or removing energy in the form of heat is needed to cause a substance to undergo a phase change. This extra energy helps break the intermolecular forces holding the particles together in their current phase, allowing them to rearrange into a new phase with different properties.
When a substance is added to water and bubbles form how can you confirm the type of change that took place?
When a substance is added to water and bubbles form, this often indicates a chemical change, especially if the bubbles are gas that was not present before, such as from a reaction. To confirm the type of change, one can observe if the original substances can be recovered or if new properties emerge, such as a change in color, temperature, or the formation of a precipitate. Conducting tests for gas composition (like using a lit splint to check for hydrogen) can further confirm a chemical change. If the substance can be separated back out unchanged, then it may be a physical change instead.
Can amount of each substance in a mixture cannot change?
The amount of each substance in a mixture can change if more of a substance is added or removed, causing the proportions of the substances in the mixture to change. However, the total amount of each substance in the mixture will remain constant.
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.
Is a liquid added to water a pure substance or a mixture?
A mixture is formed.
When sugar is added to water does this make a pure substance or a mixture?
It makes a mixture.
Is concrete hardening an example of chemical or physical change?
Concrete hardening is an example of a chemical change. When water is added to the cement mixture, a chemical reaction occurs between the water and the cement particles, resulting in a new substance with different properties than the original components.
Is dishwater an element mixture compound or pure substance?
yes
What is the difference between partial molal quantities and partial molar quantities?
During the determination of the partial molal quantities the weight of the solution to which a substance is added is taken into consideration while in case of the partial molar quantity the volume is taken into consideration.

When sugar is added to tea does the substance change?
No
What is a substance like manure added to soil to make it more productive?
mixture of nitrates
How will a substance change if energy is added to the liquid at 20 degrees Celsius?
The substance will get hawter
