Mixing sugar with iodine solution is a physical change because no new substances are formed. The sugar and iodine solution retain their individual chemical properties even when mixed together.
Mixing iodine with cornstarch does not result in a chemical reaction. Instead, it forms a physical mixture in which the iodine molecules become trapped within the starch molecules, causing the mixture to change color. The iodine acts as an indicator of the presence of starch.
Chemical, When something changes in color, it is a sign of a chemical change.
Mixing powdered sugar and iodine is a physical change, not a chemical change. In this case, the substances are simply being combined physically, without any new substances being formed. A chemical change would involve a reaction between the powdered sugar and iodine, resulting in the formation of new substances with different chemical properties.
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
physical because its a mixture and doesnt chemically combine
Its a physical change as there is no reaction.
No, mixing Elmer's glue and liquid starch is a physical change. A chemical change involves the formation of new substances with different chemical properties, while mixing these two substances does not result in a chemical reaction.
No. Making mixtures are physical changes and the chemical substances will not change.
DEATH
Physical change as no new substance is formed and the properties have also not changed. Hope it helps!
It is a chemical change because the products, H2 and HCl, are completely different from the reactants in their physical and chemical properties.
