When an ionic compound dissolves, the ions are surrounded by water molecules, separate and move into the solutions. The ions exist in the same valence state as they did in the ionic compound.
The ions present due to the dissolution of nickel chloride will be Ni⁺² and Cl⁻.
The ions already present due to water will be H⁺ and OH⁻.
An increase in the temperature will speed up the reaction by increasing the frequency and efficiency of the collisions of molecules.
C. a metal.
Hope it helps!
You would observe, trying to identify if there's a minimum difference in each beaker. Like, colour, or using an <em>bagueta </em>(idk how to say it in english), churning it or something like that.
Answer:
5
Explanation:
the Carbon's atomic number is 6, but when its charge is 1+ it means that it lost an electron .. so 6-1=5
