Explanation:
<em>We </em><em>know </em><em>that </em><em>metals </em><em>are </em><em>good </em><em>conductor </em><em>of </em><em>heat</em><em>. </em><em>so </em><em>it </em><em>allows </em><em>the </em><em>heat </em><em>to </em><em>flow </em><em>through </em><em>them </em>
<em>.</em><em> </em><em>So </em><em>as </em><em>we </em><em>know </em><em>the </em><em>spoon </em><em>is </em><em>a </em><em>metal </em><em>which </em><em>is </em><em>left </em><em>on </em><em>a </em><em>bowl </em><em>of </em><em>hot </em><em>soup </em><em>allows </em><em>heat </em><em>to </em><em>flow </em><em>through </em><em>it </em><em>easily </em><em>so </em><em>if </em><em>becomes </em><em>warm</em><em>. </em>

Here is the correct answer of the given question above. Ferrocene has a higher melting point that acetylferrocene because it takes more energy to overcome the intermolecular forces between atoms. <span>Acetylferrocene melts at 80 degrees and Ferrocene melts at 170. Hope this answer helps.</span>
As I understand from your question, we should synthesize nickel sulfate first from nickel (II) oxide and sulfuric acid and second from nickel carbonate and sulfuric acid.
The chemical reactions will look like this:
NiO (s) + H₂SO₄ (aq) → NiSO₄ (aq) + H₂O (l)
NiCO₃ (aq)* + H₂SO₄ → NiSO₄ (aq) + H₂CO₃ (aq)
but carbonic acid will decompose to carbon dioxide and water
H₂CO₃ (aq) → CO₂ (g) + H₂O (l)
(*) NiCO₃ has a poor solubility in water, but enough to start the reaction.
Answer:
alkenes and alkynes are considered as unsaturated hydrocarbons because they are capable of reacting with hydrogen in the presence of a catalyst to form a saturated hydrocarbon (alkanes)
Explanation:
A saturated compound contains a chain of carbon atoms joined by single bonds, with hydrogen atoms attached to each carbon atom.
Propane for example, CH₃-CH₂-CH₃.
It is saturated because all the carbon atoms holds maximum number of hydrogen atoms.
Alkenes such as Propene (CH₂=CH-CH₃) and alkynes like Propyne,
(CH₃-C≡C-H) are unsaturated because the central carbon atoms contain less number of hydrogen atoms than they possibly could.
