Ice is solid water.
Water is a pure substance, a chemical compound composed of two hydrogen atoms and one oxygen atom..
Is aluminum foil a pure element?
aluminum metal (symbol Al, atomic # 13) is an element and therefore a pure substance.
Can you touch dry ice?
Dry Ice temperature is extremely cold at -109.3°F or -78.5°C. Always handle Dry Ice with care and wear protective cloth or leather gloves whenever touching it. An oven mitt or towel will work. If touched briefly it is harmless, but prolonged contact with the skin will freeze cells and cause injury similar to a burn.

Will dry ice kill you?
This extreme cold makes the solid dangerous to handle without protection due to burns caused by freezing (frostbite). While generally not very toxic, the outgassing from it can cause hypercapnia (abnormally elevated carbon dioxide levels in the blood) due to buildup in confined locations.
Is dry ice dangerous?
Dry ice, which is the solid form of carbon dioxide, is not dangerous if it is stored and used correctly. It can present hazards because it is extremely cold and quickly sublimates into carbon dioxide gas. While carbon dioxide is not toxic, it can build pressure or displace normal air, potentially causing problems.

Is honey a mixture?
Honey is a homogeneous mixture because it has the properties that define homogeneous solutions or mixtures. It is produced by bees, obviously, and the component parts are uniformly distributed throughout the substance. … All of this makes honey a homogeneous substance.
Is a wood a compound?
Wood is composed of a number of compounds such as lignin, cellulose, water, hemicellulose, etc. … Unlike a compound, wood does not have a fixed chemical formula. Hence, wood is a mixture. In fact, wood is a heterogeneous mixture, since these constituent compounds are mixed unevenly in a given wood sample.
Is Vinegar a mixture?
Vinegar is a homogenous mixture of acetic acid and water. As the mixture created has only one phase it is a solution. Mixtures are created by mixing two or more chemical substances. If the result has more than one phase it is referred to as a mixture else it is called a solution.
Is Fruit Salad a mixture?
