The answer is:

2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O

<h2>Further Explanation </h2>

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.

How many of the following species are paramagnetic? sc3+ br- mg2+ se?
Aloiza [94]
Answer:
           One: <u>Selenium</u> is Paramagnetic

Explanation:
                   Those compounds which have unpaired electrons are attracted towards magnet. This property is called as paramagnetism. Lets see why remaining are not paramagnetic.

Electronic configuration of Scandium;

Sc  =  21  = 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹

Sc³⁺  =  1s², 2s², 2p⁶, 3s², 3p⁶ 

Hence in Sc³⁺ there is no unpaired electron.

Electronic configuration of Bromine;

Br  =  35  = 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁵

Br⁻  =  1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶

Hence in Br⁻ there is no unpaired electron.

Electronic configuration of Magnesium;

Mg  =  12  = 1s², 2s², 2p⁶, 3s²

Mg²⁺  =  1s², 2s², 2p⁶

Hence in Mg²⁺ there is no unpaired electron.

Electronic configuration of selenium;

Se  =  34  = 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁴

Or,

Se  =  34  = 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4px², 4py¹, 4pz¹

Hence in Se there are two unpaired electrons hence it is paramagnetic in nature.

Which pair shares the same empirical formula?
ZanzabumX [31]

Answer:- 3. CH_3 and C_2H_6

Explanations:- An empirical formula is the simplest whole number ratio of atoms of each element present in the molecule/compound.

For example, the molecular formula of benzene is C_6H_6 . The ratio of C to H in it is 6:6 that could be simplified to 1:1. So, an empirical formula of benzene is CH.

In the first pair, the ratio of C to H in first molecule is 2:4 that could be simplified to 1:2 and  the empirical formula is CH_2 . In second molecule the ratio of C to H is 6:6 and it could be simplified to 1:1. and the empirical formula is CH. Empirical formulas are different for both the molecules of first pair and so it is not the right choice.

In second pair, C to H ratio in first molecule is 1:2, so the empirical formula is CH_2 . The C to H ratio for second molecule is 1:4, so the empirical formula is CH_4 . Here also, the empirical formulas are not same and hence it is also not the right choice.

In third pair, C to H ratio in first molecule is 1:3, so the empirical formula is CH_3 . In second molecule the C to H ratio is 2:6 and it is simplified to 1:3. So, the empirical formula for this one is also CH_3 . Hence. this is the correct choice.

In fourth pair, first molecule empirical formula is CH. Second molecule has 2:4 that is 1:2 mole ratio of C to H and so its empirical formula is CH_2 . As the empirical formulas are different, it is not the right choice.

So, the only and only correct pair is the third one. 3. CH_3 and C_2H_6
