Polonium 210, botulinum toxin, and the toxin from the poison frog are perhaps the most toxic and deadly poisons known to mankind. Polonium 210 is so radioactive that a gram of it can kill 10 million people and the few that will survive will undeniably have cancer. Botulinum toxin is the most lethal toxin. A few drops could kill billions of people. It causes botulism which weakens the muscles of the body and eventually leads to death. The poison frog is used to add poison to arrows of hunters in South America. Simply touching the small frog will surely cause death either by cardiac arrest or lung failure.
Explanation:
To balance a chemical equation implies that we are conserving the number and mass of the reacting species.
Chemical equations must obey the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed".
This suggests that mass is conserved.
The number of atoms on the reactant side must be equal to that on the product end.
Before proceeding, check the species to see if they have equal number of atoms on both sides:
Fe + CuCI₂ → FeCI₂ + Cu
Elements reactants products
Fe 1 1
Cu 1 1
Cl 2 2
We can see that the equation is already balanced

Explanation:
The <span>simple machine found on the head of the ax is </span>Wedge. A wedge is an inclined plane that can be moved. When an ax is used
to split wood, the ax handle
exerts a force on the blade of
the axe, which is the wedge. That force pushes the wedge
down into the wood. The wedge in turn exerts an
output force splitting the wood in two.
The focal length, like you said it's the distance between the FOCAL point and the mirror.
Hope this helps.... :)
