there is a phase change that is water(liquid) is converted into ice now the question arrives that it is a pure substance or not? if its chemical composition is the same during the phase change then it is a pure substance otherwise not.
NO!!! It is NOT a mixture. Dry Ice is solid Carbon Dioxide. , where the carbond dioxide molecules arrange themselves in a regular order (lattice). Whereas in gaseous form the molecules are further apart, moving and arranged irregularly.
compound
Lemonade is not a pure substance because it is a mixture of water, lemon juice, sugar, and possibly other ingredients such as ice. Each component can be separated from the mixture, indicating it is not a pure substance.
Crushed ice is a mixture because it is made up of different types of ice crystals. It is a homogeneous mixture because the composition is uniform throughout, with all parts having the same properties.
solid called dry ice.
Ice is solid H2O so it is a pure substance, at least ideally.
NO!!! It is NOT a mixture. Dry Ice is solid Carbon Dioxide. , where the carbond dioxide molecules arrange themselves in a regular order (lattice). Whereas in gaseous form the molecules are further apart, moving and arranged irregularly.
Yes, dry ice is a substance. It is frozen carbon dioxide.
compound
Dry ice is solid carbon dioxide, CO2. It is a pure substance, a chemical compound. It sublimes at room temperature goinf from solid to gas without turning into a liquid.
yes
If there is no salt or substance that makes it impure it is a pure mixture
Ice is water (H2O) in it's solid state. It is a substance because it is entirely composed of one molecule and is not "mixed" with anything.
water is pure so is homogeneous ice is pure so is homogeneous oil is pure so is homogeneous
White as pure, dry substance
Ice water is a compound.
hell yes it is
