KCN kills a human being in 0.5 second.
What is the formula for the compound that forms from potassium and cyanide?
To answer this you need a roman numeral on gold to know the charge on it. Assuming it would be (I)... the formula would be KAu(CN)2
How do you prepare kcn?
We can prepare KCN by the reaction of KOH and HCN.Where HCN can be generated by the pyrolysis of formamide.
What number represents the word mole?

What salt is poisonous?
Examples of poisonous salts: KCN, HgCl2, NaCN.
Does a mole of helium gas have the same number of molecules as a mole of lead and why?
A mole of anything has the same number of molecules as a mole of anything else. The why comes from the fact that this is the standard definition as agreed by scientists. We have to have standards for things to work. A mole of anything contains an Avagadro number of particles. That number is 6.022 x 1023
How much is a mole?
A mole is equal to 6.022 x 1023. This number is called Avagadros number. A mole is generally abreiviated as "n".
What is meant by the Avogadro number and why is it relevant to the mole?
Avogadro's number is the number of atoms or molecules of a substance that are present in one mole of that substance. It is relevant to the mole by its very definition!
Can a mole represent a molecule?
A mole represents a set number of molecules, not just 1 molecule. There are avagadro's number of molecules in a mole. Avagadro's number: 6.022x10^23
What does an Avogadro's number of a substance is called a mole mean?
It is the number of particles in a mole of any substance
Does 0.1 M KCN have a pH greater than 7.0?
Yes, a 0.1 M solution of KCN will have a pH greater than 7.0. Potassium cyanide (KCN) produces hydroxide ions when dissolved in water, leading to an increase in pH above 7.0.
