Which type of bond results when one or more valence electrons are transferred from one atom to another?(1) a hydrogen bond
(2) an ionic bond
(3) a nonpolar covalent bond
(4) a polar covalent bond
Answers
To solve this we must be knowing each and every concept related to an ionic bond. Therefore, the correct option is option 2 among all the given options.
What is an ionic bond?
Ionic bond, also known as electrovalent bond, is a kind of connection generated in a chemical molecule by the electrostatic attraction of oppositely charged ions.
Whenever the valence (outer portion) electrons with one atom are permanently transferred to another, a bond is formed.
The atom that loses electrons has become a positive ion (cation), whereas the atom that obtains electrons is becoming a negatively charged ion (cation) (anion). When one or more valence electrons are transferred from one atom to another, then the bond formed is an ionic bond.
Therefore, the correct option is option 2 among all the given options.

Cl₂ = 71.0 g/mol Na = 23.0 g/mol
2 Na + Cl₂ = 2 NaCl
2 x 23 g Na -------> 71.0 g Cl₂
96.6 g Na ----------> ?
Mass Cl₂ = ( 96.6 x 71.0 ) / ( 2 x 23 )
Mass Cl₂ = 6858.6 / 46
= 149.1 g of Cl₂

2H₂ + O₂ ⇒ 2H₂O
Since the hydrogen is the limiting reagent (meaning if the hydrogen runs out the reaction stops), we need to compare the mole ratio between hydrogen and water.
The mole ratio between H₂ and H₂O is 2:2, or 1:1 (as seen on the coefficients of the balanced equation)
And so for every mole of hydrogen, it will be equal to water. Since hydrogen is 4 moles, 4 moles of water would be created.
So we use the coefficients of H₂ and H₂O in order to answer this question.
The number of moles of H2O is proportional to the number of moles of H2 as much as 4 moles
The calculation reference is the mole of the limiting reagent of the mole of H2O is based on the mol of H2
Stokiometry in Chemistry learns about chemical reactions mainly emphasizing quantitative, such as calculation of volume, mass, number, which is related to the number of ions, molecules, elements, etc.
In chemical calculations, the reaction can be determined, the number of substances that can be expressed in units of mass, volume, mole, or determine a chemical formula, for example, the substance level or molecular formula of the hydrate.
- The reaction equation is the chemical formula of reagents and product substances
- A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
- In the reactionequation there are also manifestations of reagent substances namely gas (g), liquid (liquid / l), solid (solid / s) and solution (aqueous / aq).

Answer
Reactions that occur:
2H₂ + O₂ ⇒ 2H₂O
The reaction coefficient shows the mole ratio of reactants and reaction products
In determining the mole of the reaction, the calculation reference is the mole of the limiting reagent or the reagent that runs out. Because here it is stated that oxygen (O₂) is reacted under excess conditions, the hydrogen ratio becomes the limiting reagent. So the determination of the mole of H₂O is based on the mol of H₂
In the equivalent equation, the mole of H₂ and H₂O is 2: 2 or can be simplified to 1: 1, so the number of moles of H₂O is proportional to the number of moles of H₂ as much as 4 moles

So you have 14.31g Carbon, 1.2g Hydrogen, and 84.49g of Chlorine. Next you divide each by their molar masses to get moles of each.
Carbon= 14.31g Hydrogen= 1.2g Chlorine= 85.49g
12.01g 1.01g 35.45g
= 1.19moles = 1.188moles = 2.411moles
Next you divide each of those numbers by the smallest, in this case, Hydrogen.
Thus,
Carbon= 1.19moles Hydrogen= 1.188moles Chlorine= 2.411moles
1.188moles 1.188moles 1.188moles
=1.002 =1 =2.02
These are all close enough to round, so your final empirical formula is: CHCl2
Hope that helps!!

Answer : The answer is, Chain reaction.
Explanation :
Chain reaction : It is defined as the series of successive elementary processes in which the active intermediate species are consumed and regenerated before the products are obtained.
It is a self-sustaining series of the chemical reactions where the product obtained from one reaction are the reactants in the next reaction and so on.
Hence, a chain reaction is a self-sustaining series of chemical reactions in which the product of one reaction are the reactants in the next reaction.
