What type of reaction is the reaction of calcium oxide with water

Definition: Oxide An oxide is a chemical compound that contains at least one oxygen atom chemically bonded to an atom of another element. There are a vast number of oxides of different elements, including both metals and nonmetals. Oxides have many uses in our society. Calcium oxide ( C a O) is used in the production of concrete, and nitrous oxide ( N O 2) is used as an anesthetic for dental procedures. Example 1: Defining the Constituent Parts of an Oxide Which element does an oxide—a compound containing two elements—contain at least one atom of? Answer An oxide is a chemical compound that contains the element oxygen. The oxygen in a compound will be bonded to one another element, creating a binary compound. For example, when copper metal reacts with oxygen gas, copper(II) oxide ( C u O) is formed. An oxide, therefore, contains at least one atom of oxygen. Common metal oxides include magnesium oxide, sodium oxide, and copper(II) oxide. The ease with which metal oxides form relates to the reactivity of the metal. The group 1 alkali metals are well known for being very reactive and are consequently stored under oil to prevent reactions with oxygen and moisture in the air. If a piece of a group 1 metal such as lithium is freshly cut, the shiny surface soon becomes dull as the lithium reacts with oxygen in the air, forming a layer of lithium oxide ( L i O 2): 4 L i ( ) + O ( ) 2 L i O ( ) s g s 2 2 Less reactive metals, such as copper, will not react as readily with oxygen. O...

Hint : We know that the reaction of water and calcium oxide forms calcium hydroxide. There is more than one way to classify this reaction. These two reactions are very common in chemistry and we can easily find either of them in any chemical reaction. As it can be proposed from their names itself, combination reaction is formation of bonds and decomposition is breaking of bonds. Complete Step By Step Answer: Firstly, let us discuss combination reactionsCombination Reaction: It is also known as a synthesis reaction where two or more elements or compounds, known as the reactants, react with each other and combine to form a single compound, called the product. The combination of two or more reactants to give a single product is known as combination reaction. Combination reactions can be between two different compounds like in the above reaction where magnesium oxide combines with carbon dioxide to give magnesium carbonate. It can also be carried out between two elements or a compound and an element. Decomposition reaction: It is the type of chemical reaction in which a single compound breaks down into two or more elements. These reactions are generally endothermic, as breaking of bond requires a high amount of energy. A simple example of decomposition reaction is hydrolysis of water where a water molecule is broken down into hydrogen and oxygen gas. The reaction between calcium oxide and water is a combination reaction. The reaction of mercuric oxide with strong heat is a dec...

\( \newcommand\) • • • • • • • • • This page discusses the reactions of the oxides of Period 3 elements (sodium to chlorine) with water, and with acids or bases where relevant (as before, argon is omitted because it does not form an oxide). A quick summary of the trend The oxides: The oxides of interest are given below: Na 2O MgO Al 2O 3 SiO 2 P 4O 10 SO 3 Cl 2O 7 P 4O 6 SO 2 Cl 2O The trend in acid-base behavior can be summarized as follows: Acidity increases from left to right, ranging from strongly basic oxides on the left to strongly acidic ones on the right, with an amphoteric oxide (aluminum oxide) in the middle. An amphoteric oxide is one which shows both acidic and basic properties. This trend applies only to the highest oxides of the individual elements (see the top row of the table), in the highest oxidation states for those elements. The pattern is less clear for other oxides. Non-metal oxide acidity is defined in terms of the acidic solutions formed in reactions with water—for example, sulfur trioxide reacts with water to forms sulfuric acid. They will all, however, react with bases such as sodium hydroxide to form salts such as sodium sulfate as explored in detail below. Sodium Oxide Sodium oxide is a simple strongly basic oxide. It is basic because it contains the oxide ion, O 2-, which is a very strong base with a high tendency to combine with hydrogen ions. Reaction with water: Sodium oxide reacts exothermically with cold water to produce sodium hydroxide s...

The chemical is ionic, with aqueous and electrolytic dissociations both producing calcium ions and hydroxide ions. Production and uses Calcium hydroxide is usually produced through the reaction ofcalcium oxide (CaO) with water (H 2O). This CaO + H 2O → Ca(OH) 2This reaction occurs when water is added to dry In the construction industry, calcium hydroxide is a main ingredient in Calcium hydroxide is used as a neutralizing chemical, because it reacts with Calcium hydroxide is one of many chemicals added to industrial scrubbers that remove nitrogen and sulfur oxides from the exhaust gases that are a byproduct of many industrial processes. Removing these oxides helps to reduce the amount of acid rain that forms due to industrial pollutants.

In 1920 calcium hydroxide was first used in root canal fillings. Any exposed dental pulp was treated with calcium hydroxide, and in the mid-20th century capping dental pulp with calcium hydroxide became standard practice.

\( \newcommand\) • • • • • • • • • • • • • • • • • Water is composed of two hydrogen atoms and an oxygen atom. It exhibits polarity and is naturally found in the liquid, solid, and vapor states. Its polarity makes it a good solvent and is commonly known as the universal solvent. Because of its abundance on earth, it is important to note that it is involved in many chemical reactions. Many of these chemical reactions behave in trends that can be categorized using the periodic table. Group 1: Alkali Metals A common characteristic of most 2(g) from water. This is represented by their large, negative electrode potentials. In this event, the Group 1 metal is oxidized to its metal ion and water is reduced to form hydrogen gas and hydroxide ions.

Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime. Here are the equations for this reaction: Calcium oxide + water → calcium hydroxide C a O + H 2 ​ O → C a ( O H ) 2 ​ A lot of heat is produced in the reaction, which may even cause the water to boil.Hence it is a combination reaction as well as exothermic reaction.
