Answer:
4O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 3H₂O (g)
4 would be the smallest possible integer for O₂
Explanation:
The balanced equation is this one:
8O₂ (g) + C₅H₁₂ (g) → 5CO₂ (g) + 6H₂O (g)
If we divide stoichiometry /2 (the half) we can consider that we use, the smallest possible integers.
8/2O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 6/2H₂O (g)
4O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 3H₂O (g)
Answer:
Relative and average atomic mass both describe properties of an element related to its different isotopes. However, relative atomic mass is a standardized number that's assumed to be correct under most circumstances, while average atomic mass is only true for a specific sample.
Explanation:
Answer:
A.
Atoms cannot be created or destroyed by chemical reactions.
Explanation:
Pure substance - Ice cubes
Mixture - Homogenous sea water , lemonade
Pure substance are the substance which have constant chemical composition and characteristic.
Mixture is material made up of two or more chemical substance which are not chemical bonded. These materials in mixture are not in definite proportion.
As water ice cubes has only water in it thus it is pure substance.
Homogeneous sea water contains various salts and impurities in it thus it is mixture.
Lemonade contains lemon juice and water in it . Thus, it is mixture.
