Answer:
New kinds of products forms and the reaction is not easily reversible.
Explanation:
The only way to be certain that a chemical change has occurred is by finding out if new kinds of products have been formed.
A chemical change is a change in which new kinds of matter is formed. It is always accompanied by energy changes.
The process is not easily reversible.
Examples of chemical changes are combustion, rusting of iron, precipitation and souring of milk.
Answer:
True
Explanation:
This is because the Earths ionisphere was distrubed which makes radio communications.
Mitosis creates a diploid duplicate of the parent cell that is genetically the same as its parent cell, and meiosis creates haploid cells that are genetically different than their parent cell.
A chemical separation is a separation method that involves change in the chemical composition of one of the solutions that are to be separated in order to a new physical properties of one part reached leaving the rest alone.
For example, When we add a chemical to the solution that will precipitate only one part of the solution leaving the rest.
A physical separation is a separation in which solutions are separated on the basis of their physical properties.
For example, If we use physical separation method in separating two oils with different specific volumes then these two oils are separated on the basis of their settling.
