Answer:
(Density = mass/volume) Arrange the following in order of increasing density - air, exhaust from chimneys, honey, water, chalk, cotton and iron. Answer: The increasing order of density is air < exhaust from chimney < cotton < water < honey < chalk < iron.

Explanation:
Answer:
reducing agent
Explanation:
A reactant that loses electrons and is oxidized is the reducing agent because it provides electrons to the reactant that gets reduced.
Answer:
D= there is the same number of each type of atoms on the right side and left side of the equation.
Explanation:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
