Chemical reaction - The chemical reactions are classified into different classes depending upon the type of chemical changes take place these reactions are as follows:

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>Combinat</u><u>ion</u><u> </u><u>react</u><u>ion</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>

Combination reaction - A reaction in which two are more reactance combined to form a single product is call combination reaction

  • calcium oxide reacts vigorously with water to form calcium hydroxide the reaction is highly exothermic a lot of heat is produced during the reaction
  • CaO(s) + H2O(l) -------------- CH3OH(l)

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>Decomposition </u><u>Reaction</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>

Decomposition reaction - aur reaction in which a single reactant breakdown to form two or more products is known as decomposition reaction this reaction is opposite to combination reaction on the basis of the form of energy required for the reaction this reaction of three types

  • thermal decomposition this reaction use the energy in the form of heat for the decomposition of reactant
  • Electrolysis these reactions involves the use of electrical energy for the decomposition of the reactant molecules
  • Photolysis these reactions involved the use of light energy for the purpose of decomposition

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>Displace</u><u>ment</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>reaction</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>

Displacement Reaction - when a more reactive element displays less reactive element from its compound it is called displacement reaction.This is of types.

  • Single displacement reaction - it is a type of chemical reaction where an element reacts with the compound and takes the place of another element in that compound is called single displacement Zn + cuso4 --------- ZnSO4 + cu

  • Double displacement reaction - the reaction in which two different oils or group of atom in the reactant molecules are displaced by each other is called double displacement reaction it is also called precipitation reaction as precipitate is produced in such reactions

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>Oxidation</u><u> and reduction </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>

Oxidation - it is the process in which oxygen is added to a substance or hydrogen is removed from a substance

Reduction - it is the process in which oxygen is removed from a substance or hydrogen is added to a substance

Redox reaction - these are the reactions in which oxidation and reduction takes place simultaneously or call redox reaction

<u>Endothermic and Exothermic</u>

Endothermic - the reaction which are a complaint by the evolution of heat are called exothermic reaction all the reaction in which heat is released along with the formation of product are called exothermic reaction

Endothermic - the reaction which occur by the absorption of heat energy either in the form of light electricity are called endothermic reaction

What is defined as the number of atoms surrounding an atom in a crystal lattice?
Simora [160]

Answer:

coordination number

Explanation:

Coordination number -

In a crystal lattice , the number of atoms that are surrounded to a particular atom , is referred to as the coordination number of the crystal.

In the field of crystallography and chemistry , it is also called the ligancy.

In coordination chemistry , the number of ligands attached to the central metal atom is also known as the coordination number of the coordination compound.

Hence, from the given statement of the question,

The correct term is coordination number.

Un gas ocupa un volumen de 12 litros a una presión de 912 mm Hg. Si permanece constante la temperatura, ¿A qué presión el gas oc
adoni [48]

Answer:

The  pressure occupied is 1, 8 atm.

Explanation:

We use the Boyle´s Mariotte ´s law: for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1= P2xV2. The unit of pressure is converted to mmHg in atm.

760 mmHg----1 atm

912 mmHg---x= (912 mmHg x 1 atm)/760 mmHg=1,2 atm

P1xV1= P2xV2

P2=P1xV1/V2= 1,2 atm x 12 L/ 8L= <em>1, 8 atm</em>

What is the difference between a theory and a scientific law?
Westkost [7]
Scientific laws and theories have different jobs to do. A scientific law predicts the results of certain initial conditions. ... In contrast, a theory tries to provide the most logical explanation about why things happen as they do.

the reaction of aluminum with chlorine gas is shown 2Al + 3Cl2 -&gt; 2AlCl3 based on this equation how many molecules of chlorin
Vanyuwa [196]

45 molecules of chlorine gas (Cl₂) are needed to react with 30 atoms of aluminum (Al)

The balanced equation for the reaction is given below:

2Al + 3Cl₂ —> 2AlCl₃

From the balanced equation above,

2 atoms of Al required 3 molecules of Cl₂.

With the above information, we can determine the number of molecules of Cl₂ needed to react with 30 atoms of Al. This can be obtained as follow:

From the balanced equation above,

2 atoms of Al required 3 molecules of Cl₂.

Therefore,

30 atoms of Al will require = \frac{30 * 3}{2}\\ = 45 molecules of Cl₂.

Thus, 45 molecules of chlorine gas (Cl₂) are needed to react with 30 atoms of aluminum (Al)
