Answer:
The main reason for this is the ingredients found in the paint. Different Ingredients are used to make different types of color paints, therefore when each of these paints is used in connection with the solvent the different chemicals in the paint create a certain reaction with the chemicals in the solvent, and each reaction may be different in each color depending on the chemical compound.
Answer:
- B. Precipitation require the diffusional activation energy plus an additional energy to form the precipitate.
Explanation:
Precipitation is the creation of a solid from a solution. When the reaction occurs in a liquid solution, the solid formed is called the precipitate.
The formation of a precipitate indicates the occurrence of a chemical reaction.
Precipitation of carbide requires alot of energy which the diffusion activational energy alone cannot achieve and this was calculated to be 225.6 kJ/mol.
Answer:
E= 15 GPa.
Explanation:
Given that
Length ,L = 0.5 m
Tensile stress ,σ = 10.2 MPa
Elongation ,ΔL = 0.34 mm
lets take young modulus = E
We know that strain ε given as
We know that
Therefore the young's modulus will be 15 GPa.
