Answer:
Barium and Calcium
Explanation:
When heated with chlorine,
Both calcium and barium are able to form ionic bonds.
Hydrogen can only form bonds that are partial positive. It is not strong enough to be considered an ionic bond.
Silicon forms strong covalent with chlorine, called silicon tetrachloride. The structure is in diamond form which requires a lot of heat energy to break the bonds are way more than energy needed to break the bonds between calcium chloride.
Krypton is an inert element which does not form bonds with any elements under standard conditions
Mendeleev organized it by the atomic mass and mosely did it by atomic number
<u>Answer:</u> Copper (I) iodide will precipitate first.
<u>Explanation:</u>
We are given:
of CuCl =
of CuI =
Concentration of
Concentration of
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.
Putting values in above equation, we get:
Concentration of copper (I) ion =
Putting values in above equation, we get:
Concentration of copper (I) ion =
For the precipitation of copper (I) ions, we need less concentration of copper (I) ions. So, copper (I) iodide will precipitate first.
Answer: The total pressure of the container is 231.97 kPa.
Explanation:
Given: ,
,
Total pressure is the sum of pressure of each component of the gas present in a vessel or container.
Hence, total pressure of the container is calculated as follows.
Thus, we can conclude that the total pressure of the container is 231.97 kPa.
