Answer: B) combustion reaction.
Explanation:
A) acid-base reaction: When an acid reacts with a base, to form metal salt and water, this type of reaction is Acid Base reaction.
Example:
B) combustion reaction: When a hydrocarbon reacts with oxygen to produce carbon dioxide and water, this type of reaction is combustion reaction.
C) precipitation reaction: a reaction in which aqueous solution of two compounds on mixing react to form an insoluble compound which separate out as a solid are called precipitation reactions.
D) gas evolution reaction: a reaction in which one of the product is formed as a gas.
Answer:
Explanation:
Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions.The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.
Answer:
The sugar particles are so small that they have dissolved in the water, and can easily pass through the filter.
Answer:
The reactants are the substances that start the chemical reaction. The products are the substances that are produced in the chemical reaction.
Explanation:
Answer:
Oxygen in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element
