Is tomato an element compound or mixture?
It is a mixture.
Is electricity a compound mixture or element?

When you shake sugar and Sand together in a test tube you cause a?
physical mixture of the two substances, as they do not chemically react with each other. After shaking, the sugar and sand will be physically mixed together but can be separated by a process such as filtration.
Is flour and sugar in a bowl be a compound or mixture?
flour is mixture
Which of the following is a physical change?
Forming a mixture
Can a homogeneous mixture be separated by physical changes?
Yes, a homogeneous mixture can be separated by physical changes. Techniques like filtration, distillation, and evaporation can be used to separate the different components of a homogeneous mixture based on their physical properties such as size, boiling point, or solubility.
Do chemical changes take place when a mixture is made?
No!chemical changes do not take place when a mixture is made.The constituent substances of the mixture retain their own chemical composition.Thus only physical changes take place.
What criteria are used to distinguish between a chemical and physical change?
Chemical changes involve the formation of new substances with different chemical properties, while physical changes do not alter the chemical composition of the substance, only its physical state or appearance. Chemical changes are usually irreversible, while physical changes are reversible.
Can you make a sentence with mixture and physical change?
A mixture is a mix of substances such as blood or juice, physical changes only alter the form of the object not the substance itself.

Is concrete a compound after the water evaporates and it hardens?
Concrete is not a compound after water evaporates and it hardens. Concrete is a mixture of aggregate materials (such as sand and gravel) and cement, which binds the materials together. When water is added to the mixture, a chemical reaction occurs with the cement that causes it to harden and bind the aggregate materials together.
What is physically happening when water is dissolving a substance?
when we dissolve a substance then first of all there may occur physical change like shape,colour,temperature etc. these changes are called physical changes.
What happens to some when a mixture is heated?
When a mixture is heated, the individual components may start to react with each other, leading to chemical changes such as combustion or decomposition. The physical properties of the mixture can also be altered, such as changes in state (solid to liquid, liquid to gas) or separation of components based on their different boiling points.
