Identifying Characteristics of Atoms

Chemistry
1 answer:
Anon25 [30]3 years ago
8 0

Explanation:

The number of protons in an atom is the atomic number.

Mass number is the number of protons plus neutrons in an atom.

  Mass number  = number of protons + number of neutrons

Atomic number  = number of protons

Atomic number gives the symbol of the element

Number        Number      Atomic      Mass          Symbol

 Protons       neutrons     Number    Number

     A                    7                 B              15                C

     D                   E                 26             56               F

A, number of protons  = B

 Mass number  = protons + neutrons

          15  = protons + 7

          Protons  = 15 - 7  = 8

Atomic number 8 is for oxygen = C

Atomic number  = number of protons  = D = 26

Number of neutrons ;

          E =    Neutrons  = mass number - protons  = 56  - 26  = 30

Atomic number 26 is for Iron = F

Which of the following will increase entropy in a reaction?
Dafna11 [192]

The condition that will increase the entropy in a reaction is heating up the reaction (option B).

<h3>What is entropy?</h3>

Entropy in chemistry is the measure or degree of the disorder or randomness present in a chemical system.

In a chemical reaction, reacting substances called reactants collide with one another to form products.

However, the degree at which the reactants collide with one another is referred to as the entropy of the reaction.

Therefore, the condition that will increase the entropy in a reaction is heating up the reaction i.e. increase in temperature.

Cavalent bonds what are they?
motikmotik

Answer:

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Explanation:

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

I hope this helps!

PbO2 + 4HCl --- PbCl2 + Cl2 + 2H2O who buys electrons and who loses electrons?​
SIZIF [17.4K]

<u>Answer:</u> Electrons are taken up by PbO_2 and they are lost by HCl

<u>Explanation:</u>

Redox reaction is defined as the reaction in which oxidation and reduction take place simultaneously. It is also called the reaction where the exchange of electrons takes place.

An oxidation reaction is defined as the reaction in which a chemical species loses electrons takes place. In this reaction, the oxidation state of a substance gets increased.

A reduction reaction is defined as the reaction in which a chemical species gains electrons takes place. In this reaction, the oxidation state of a substance gets reduced.

For the given chemical reaction:

PbO_2+4HCl\rightarrow PbCl_2+Cl_2+2H_2O

The half-reactions for this redox rection follows:

<u>Oxidation half-reaction:</u>  2HCl\rightarrow ClO_2 + 2e^-

<u>Reduction half-reaction:</u>  PbO_2+2e^-\rightarrow PbCl_2

Hence, electrons are taken up by PbO_2 and they are lost by HCl
