Answer: sorry wish o could help
Explanation:
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

Since you did not give the reactions, i cannot give the answers.
In organic and inorganic chemistry, nucleophilic substitution is a fundamental class of reactions in which an electron rich nucleophile selectively bonds with or attacks the positive or partially positive (+ve)charge of an atom or a group of atoms to replace a leaving group; the positive or partially positive atom is referred to as an electrophile. The whole molecular entity of which the electrophile and the leaving group are part is usually called the substrate.
The most general form for the reaction may be given as the following:
<span>Nuc: + R-LG → R-Nuc + LG<span>:</span></span>
An ocean ridge is an underwater mountain system which is the result of tectonic plate movement. Its formation involves two processes: ridge-push and slab pull. The former occurs when the growing bulk of the ridge pushes the rest of the tectonic plate away from the ridge. Oftentimes, they go towards a subduction zone. In this zone, the latter, which is the slab pull comes into effect. This is the weight of the tectonic plate subducted or pulled down below the overying plate tagging along the rest of the plate behind it.
They are generally located halfway between two continents.
From the ideal gas law
pv=nRT , n is therefore PV/RT
R is the
R is gas constant =62.364 torr/mol/k
P=500torr
V=4.00l
T=500+273=773k
n={(500 torr x 4.00l)/(62.364 x773k)}=0.041moles
the number of molecules=moles x avorgadro costant that is 6.022x10^23)
6.022 x 10^23) x0.041=2.469 x10^22molecules
