Answer:
In molecules, there is a pattern to the number of covalent bonds that different atoms can form. Each block with a number indicates the number of covalent bonds formed by that atom in neutral compound
Explanation:
I don't really know the answer sorry
The answer is:
2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O
In chemistry, the equation of a reaction or chemical equation is that the symbolic writing of a reaction. The statement of the reagent is written to the left of the equation and so the statement of the merchandise is written to the proper. The coefficient written to the left of a statement could be a stoichiometric coefficient, which describes the quantity of that substance involved in an exceeding reaction relative to a different substance. The reaction equation was first made by the iatrochemist Jean Beguin in 1615. in an exceeding reaction equation, reagents and products are connected by different symbols. The symbol → is employed for one-way reactions, ⇆ for two-way reactions, and ⇌ equilibrium reactions.
The reaction might be an action that always produces interchange of chemical compounds. The initial compounds or compounds involved within the reaction are called reactants. Chemical reactions are usually characterized by chemical changes and can produce one or more products that typically have different characteristics from reactants. Classically, chemical reactions involve changes involving the movement of electrons within the formation and breaking of chemical bonds, although the final concept of chemical reactions can even be applied to the transformation of elementary particles like in nuclear reactions.
Chemical compounds are pure chemicals that encompass two or several elements that will be lessened into its constituent elements by chemical reactions. as an example, dihydrogen monoxide (water, H2O) could be a compound consisting of two hydrogen atoms for every oxygen atom. Generally, this comparison must be fixed thanks to its physical nature, not a comparison made by humans. Therefore, materials like brass, YBCO superconductors, "aluminum gallium arsenide" semiconductors, or chocolate are considered mixtures or alloys, not compounds. The characteristic of compounds is the presence of chemical formulas. The statement provides a ratio of atoms in an exceeding substance, and therefore the number of atoms in an exceedingly single-molecule (therefore the statement of ethene is C2H4 and not CH2. The statement doesn't specify whether the compound consists of molecules; as an example, binary compound (table salt, NaCl) could be a compound ionic.

Explanation:
Combustion means the process by which the burning of any substance, whether gaseous, liquid or solid, occurs. In this process, the fuel oxidizes and gives off heat, and, frequently, light.
Combustion reactions are reactions where oxygen intervenes as a reagent. Oxygen has the ability to combine with various elements to produce oxides, where then oxidation is the combination of oxygen with another substance. There are oxidations that are extremely slow, but when oxidation is rapid it is called combustion.
When a substance containing carbon and hydrogen (a hydrocarbon) undergoes complete combustion, or burning, oxygen is consumed and carbon dioxide is produced, and water. Incomplete combustion can also occur when part of the fuel does not react completely because oxygen is not enough.
An Inhibitor is a substance that interferes with the action of a catalyst in a chemical reaction. A catalyst accelerates a reaction by providing an alternate mechanism with a lower activation energy. Inhibitors interrupt this process thereby reducing the efficacy of the catalyst.
A substance that interferes with the action of a catalyst in a chemical reaction is known as an Inhibitor. A catalyst is a substance that increases the rate of a chemical reaction without being changed in the process itself. It functions by offering an alternative mechanism for the reaction, typically involving a lower activation energy.
For instance, imagine a scenario where reactant substances are undergoing a change as indicated in a chemical equation. A catalyst interacts with a reactant to form an intermediate substance, which then decomposes or reacts with another reactant to regenerate the original catalyst and form the product successfully. However, an inhibitor disrupts this process, effectively decreasing the efficiency of the catalyst.

Transition metal which possesses smallest atomic mass is scandium.
The transition metals are defined as the elements in which atoms are present whose d-sub-shell is partially filled .Due to which they give rise to cations with an incomplete d-sub-shell.
They are also defined as the elements which are present in the d-block of the periodic table, which includes groups from three to twelve.These elements are called transition elements as they show a transition between highly electro-positive group 1 and highly electro-negative group 17 elements.
They have characteristic properties due to which they can exist in variable oxidation states , form colored complexes and have catalytic properties as well.These elements are all technologically very important.
