I think the awnser would be C. becuase Pure Substances are made of mostly the same material and properties Such as: Nitrogen Gas, Oxygen Gas, Carbon, Iorn, Water, Sugar and Salt.
Answer:
The properties <u>that </u><u>do not vary</u><u> with the variation in the quantity of the material are called as </u><u>intensive property</u>.
While the <u>extensive properties</u><u> are those which </u><u>vary with the variation in the quantity of the material</u>.
Intensive properties:
Mass and volume
Extensive properties:
Density and melting point

While the <u>extensive properties</u><u> are those which </u><u>vary with the variation in the quantity of the material</u>.
Intensive properties:
Mass and volume, as with increase in quantity of the material mass and volume increases.
Extensive properties:
Density and melting point, as they remain constant for a object or material
Answer:
air
Explanation:
air becuae aang is the avatar
To decrease the rate of the forward reaction you can do the following:
- decrease the concentration of the reactants
- increase the concentration of the products
- increase the pressure so the hydrogen gas will not be easily removed from the reaction
- decrease the temperature, number of collisions will decrease so the rate of the reaction will decrease
