Physical changes are changes affecting the form of a chemical substance, but not it`s chemical composition.
A physical change, changes the following:
-appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.
Answer:
C. density(the degree of compactness of a substance)
Answer:
Wetlands prevent flooding by temporarily storing and slowly releasing stormwater. Wetlands also reduce water flow, thus allowing sediments and associated pollutants to settle out. Beneficial microor- ganisms (called biofilm) live on wetland plants and process some forms of pollution.
Explanation:
Because they do not have the same qualities therefore they are different
The enthalpy change, ΔH for the following reaction 
is -452.76 kJ.
<h3>What is enthalpy change, ΔH, of a reaction?</h3>
The enthalpy change of a reaction is the heat changes that occurs when a reaction proceeds to formation of products.
- Enthalpy change, ΔH = ΔH of products - ΔH of reactants
The equation of the reaction is given below
Therefore, the enthalpy change, ΔH for the following reaction is -452.76 kJ.
