QuestionClassify these as pure substances or mixtures: 1. baking soda (NaHCO₃), 2. blueberry muffin, 3. ice (H₂O), 4. zinc (Zn), 5. Trimix (O₂, N₂, He).
Studdy Solution
STEP 1
Assumptions1. Baking soda is represented by the chemical formula
. A blueberry muffin is a baked product made from various ingredients including flour, sugar, blueberries, etc.
3. Ice is the solid form of water, represented by the chemical formula
4. Zine is represented by the symbol
5. Trimix is a mixture of oxygen, nitrogen, and helium, typically used in scuba diving
STEP 2
A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. It is composed of a single type of particle. Examples of pure substances include elements and compounds.
STEP 3
A mixture is a combination of two or more pure substances where each substance retains its own chemical identity. Mixtures can be homogeneous (uniform composition) or heterogeneous (non-uniform composition).
STEP 4
Classify baking soda. Baking soda, or , is a compound, which is a type of pure substance. Therefore, baking soda is a pure substance.
STEP 5
Classify a blueberry muffin. A blueberry muffin is made up of many different ingredients, each of which retains its own properties. Therefore, a blueberry muffin is a mixture.
STEP 6
Classify ice. Ice, or , is a compound, which is a type of pure substance. Therefore, ice is a pure substance.
STEP 7
Classify zine. Zine, represented by , is not a recognized chemical symbol or compound. If it is meant to represent an element or compound, it would be a pure substance. If it is meant to represent a mixture of substances, it would be a mixture. Without further information, we cannot definitively classify zine.
STEP 8
Classify Trimix. Trimix is a mixture of oxygen, nitrogen, and helium. Each of these gases retains its own properties in the mixture. Therefore, Trimix is a mixture.
In conclusion1. Baking soda is a pure substance.
2. A blueberry muffin is a mixture.
3. Ice is a pure substance.
4. Zine cannot be definitively classified without further information.
5. Trimix is a mixture.
