Answer: It’s true
Explanation:
Answer:
The concentration of is
The number of ion is
Explanation:
Generally the solubility product constant of HgS(s) is
This solubility product constant is mathematically represented as
Since the HgS is saturated it implies that the concentration of sulfur ion is the same as that of mercury ion s
=>
=>
substituting values
=>
From above mole of is equal to 1 L
Then x mole of will be equal to 1000 L
Therefore
=>
Now the number of ions are in 1000 L of the solution is mathematically represented as
Where is the avogadro's constant which has a value of
Substituting value
"the same";
One mole of any given thing is 6 * 10²³ of it;
One mole of H₂O is 6 * 10²³ molecules;
One mole of O₂ is also 6 * 10²³ molecules;
Therefore for both substances, there are the same number of molecules.
Fe3N2, also known as Iron (II) nitride, is an ionic compound.
Ionic compounds are compounds that consists of metals and non-metals bonded with ionic bonds. The metal ion gives up electron(s) to the non-metals.
Since iron is a metal and nitrogen is an non-metal, the bond they would form would be an ionic bond. Iron gives up 2 electrons to form iron(II) ion, while nitrogen gains 3 electrons to form nitride ion. Since one iron cannot let a nitrogen gain 3 electrons, so in the compound, there would be 3 iron (ii) ions that has given up 6 electrons in total while 2 nitride ions have gained 6 electrons in total.
