The chemical equation for the reaction is
Chromium metal is higher in the reactivity series than cobalt. Thus, chromium will displace cobalt from solutions.
Therefore, the equation for the reaction between chromium metal and cobalt (II) chloride will be written as:

<em>Chromium metal is immersed in an aqueous solution of cobalt(II) chloride. Express your answer as a chemical equation. Identify all of the phases in your answer. Enter no reaction if no reaction occurs.</em>
Answer:
4 moles, 160 g
Explanation:
The formula for the calculation of moles is shown below:
For :-
Mass of = 196 g
Molar mass of = 98 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the given reaction:
1 mole of sulfuric acid reacts with 2 moles of NaOH
So,
2 moles of sulfuric acid reacts with 2*2 moles of NaOH
Moles of NaOH must react = 4 moles
Molar mass of NaOH = 40 g/mol
<u>Mass = Moles*molar mass = = 160 g</u>
