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
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.
If there is no salt or substance that makes it impure it is a pure mixture
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
