What else can I help you with?
Is it a physical change or a chemical change when substances combine to make new substances with new properties?
Chemical change.
If two chemicals are mixed together is it a physical change?
No, mixing two chemicals together is a physical change because the substances retain their original chemical properties. The chemical composition remains the same even though they are physically combined.
When atoms combine is it a physical change or a chemical change?
When atoms combine to form molecules, it is a chemical change. In a chemical change, new substances are formed with different properties from the original substances. This is in contrast to physical changes, where the state or appearance of a substance may change without forming new substances.
What are properties that change?
the properties that change are physical and chemical properties!!! :)
When elements combine to form compounds their properties do not change.?
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
When elements combine to form a mixture their properties do not change?
When elements combine to form a mixture, they retain their individual properties. This means that the elements remain the same, and their chemical compositions do not change. Mixing elements does not result in a new substance with different properties.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Do materials change whenn physical properties are measured?
Yes, materials do change when physical properties are measured.
How do physical and chemical property's change when element becomes a compound or a mixture?
When elements combine to form compounds than the properties of elements are not pre demoninantly the same in them whether chemical or physical while in the form of mixture elements retain their properties.
When the elements combine to form compounds what happens to the chemical and physical properties of the elements?
When elements combine to form compounds, the chemical properties change because new chemical bonds are formed between the elements. This can result in new properties for the compound compared to the individual elements. The physical properties may also change, such as its melting point, boiling point, and appearance, due to the arrangement of the atoms and molecules in the compound.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Is slicing a banana a physical change or chemical change?
It's a physical change, because no chemicals are changing if I cut a banana.
