The shot answer for this question is (a) True
Answer:
I answer this question I think I said the second one
Answer:
You should not use an open flame to heat the solvent and the solvent should be heat in a stoppered flask to vapour away from the open flame
Explanation:
The electron arrangement of the outer energy level of an atom determines whether or not it will form chemical bonds. Or The shared electrons are typically near the middle of the bond between the 2 atoms, in a covalent bond.
The metal you can insert in aqueous solution of cobalt(ii) nitrate and displace cobalt is zinc.
<h3>Electrochemical series</h3>
Electrochemical series is as know as reactivity series. The electrochemical series list metals in order of decreasing reactivity.
Generally, metals higher up in the series than cobalt metal will displace cobalt(ii) ions from it solution and produce cobalt metal. Therefore, Metals like Zinc will displace cobalt(ii) form it compound.
The reaction with a solution of cobalt (II) nitrate can be represented as follows:
Co(NO₃)₂ + Zn → Zn(NO₃)₂ + Co
