COMPERE AND CONTRAST
I.
Compere
Compare is to determine two or more things in the same
case. In chemistry it is usually compared to the alkaline group equations with
alkaline earths. Example of Lithium and Magnesium equations.
II.
Contrast
Contrast is also a
comparison between two or more cases based on the difference. For example, the
difference between the alkaline group and the halogen group namely Sodium and
Chlorine.

Double Bubble Map
Double Bubble Map is a way of enriching a person's
ability to identify or demonstrate quality. It usually uses descriptive words
or descriptions and is used to compare things.

BalasHapusCan you give me another example about compere and contrast..??
Hi Fikra, thanks for the questions. This is a compare and contrast between the gold and silver:
HapusThe compare between gold and silver is:
a. Just as both gold Silver Metal
b. We know they are a group of Tránsito
c. they shine
d. Silver and gold are the same as they were diamonds
e. Gold equally crowded with Silver
The contrast between the gold and silver are:
1. Contrast color The color of gold with silver. Because gold and silver argentum aurum
2. The silver is not limited as aurum
3. aurum heavier than silver
4. The number of atoms of silver higher aurum
5. aurum more expensive than silver
Hi desiii. could you give me chemical properties of sodium and chlorine?
BalasHapusHi rahmi, thanks for the question. This is the chemical nature of chlorine and sodium
Hapus1. Chemical properties of Chlorine
Discovered in 1774 by Carl Wilhelm Scheele, he mistakenly thinks chlorine contains oxygen. This element gets its current name in 1810 by Humphry Davy. Pure chlorine chemical element is a green diatomic gas. The name of chlorine comes from the Latin word chloros, which means green, refers to the color of this gas. Chlorine gas weighs 2.5 times the air, has a stifling odor, and is highly toxic. In liquid and solid form, chlorine is a powerful oxidizing agent, bleach, and strong disinfectant agent. This element is part of a series of salt-forming halogens that can be extracted from chlorides through oxidation and electrolysis.
2. Nature of Sodium Chemistry
Sodium reacts quickly with water, snow, and ice to produce sodium hydroxide and hydrogen. When exposed to air, the sodium metal loses its silvery color and turns to gray opaque due to the formation of the sodium oxide layer. Sodium does not react with nitrogen, even at very high temperatures, but can react with ammonia to form sodium amide. Sodium and hydrogen react at temperatures above 200ºC to form sodium hydride. Sodium barely reacts with carbon and does not react with halogens. It also reacts with various metal halides to form metals and sodium chloride.
What is the basiclly contrast the element?
BalasHapusHi indri, thanks for the question. The fundamental thing in elemental equations is the similarity of the nature of two or more related elements.
HapusIf sodium and chloride are reacted what will be formed?
BalasHapusIf sodium reacts with chlorine it will form sodium chloride ie salt.
HapusExplain the advantages and disadvantages of the alkaline and halogen groups present in sodium and chlorine
BalasHapusAdvantages sodium and chlorine:
Hapus1. is a highly reactive element
2. strong sodium reductant while strong oxidation chlorine
disadvantages sodium and chlorine:
1. toxic
