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.

H2O(s) = Ice

Is dry ice a homogeneous mixture?
Dry ice is homogenous. Dry ice is made up of cooled carbon dioxide and that is why it is a pure and homogenous gas.
Is crushed ice a pure substance or a mixture and it is a homogenous or heterogenous?
Ice is solid H2O so it is a pure substance, thus homogenous, particle size is irrelevant
How is dry ice poison treated?

What substance is use to deep freeze?
Liquid Nitrogen or Dry Ice (Carbon Dioxide)
A pure substance is the what throughout?
A pure substance is the same throughout. When a substance is 100% something it is pure.
Is ice a mixture or a pure substance?
Ice is solid H2O so it is a pure substance, at least ideally.
Is dry ice a homogeneous mixture?
Dry ice is homogenous. Dry ice is made up of cooled carbon dioxide and that is why it is a pure and homogenous gas.
Is dry ice a substance?
Yes, dry ice is a substance. It is frozen carbon dioxide.
What kind of mixture is dry ice?
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.
Is ice a pure substance or not?
yes
Why ice is not a mixture?
If ice is made of pure water, then it is a pure substance with a definite composition, H2O, and not a mixture.
Is crushed ice a pure substance or a mixture and it is a homogenous or heterogenous?
Ice is solid H2O so it is a pure substance, thus homogenous, particle size is irrelevant
Is ice a pure mixture?
If there is no salt or substance that makes it impure it is a pure mixture
Is water ice and oil homogeneous heterogeneous or a pure substance?
water is pure so is homogeneous ice is pure so is homogeneous oil is pure so is homogeneous
