The reaction is not balanced
<h3>Further explanation</h3>
Given
Reaction
2Fe(s)+3O₂(g)⇒2Fe₂O₃(s)
Required
The number of atoms
Solution
In a balanced chemical equation, the number of atoms in the compound that reacts (the reactants and products) will have the same number
Reactants : Fe(s)+O₂(g)
Fe = 2 atoms
O = 3 x 2 = 6 atoms
Products : Fe₂O₃(s)
Fe = 2 x 2 = 4 atoms
O = 2 x 3 = 6 atoms
The reaction is not balanced because the number of Fe atoms is not the same
The balanced reaction should be:
4Fe(s)+3O₂(g)⇒2Fe₂O₃(s)
The half life of a scandium-46 is 84 days. The scandium-46<span> is used in oil refining as a tracer to monitor the oil movement and it emits </span><span>extremely high energetic gamma/beta radiation. So the half-life of the radioisotope scandium-46 is 84 days. The </span>Scandium 46 created by neutron activation, is a synthetic isotope of Scandium.
Addition reaction between water molecules and alkene molecules produces alcohol.
<h3>What is addition reaction?</h3>
Addition reaction generally takes place across the unsaturated carbon compounds.
When water molecule (H₂O) is added to the alkene which may be ethene (C₂H₄) molecule then formation of product i.e. ethanol (CH₃CH₂OH) takes place through the addition of hydrogen and hydroxyl group across the double bond. And reaction is shown in the attached image.
Hence formation of alcohol product takes place.

There’s no picture? regardless, if there are two numbers of electrons adding up to 8, then they will likely form an ionic bond/compound. if they can form a covalent bond with whatever amount of electrons, ex carbon 4 and 4, then it would b covalent compound
Tollen's test is a test for aldehyde giving a silver mirror in its presence, hence also called silver mirror test. Among the choice, c. pentanal is the aldehyde. Answer is C.
