Which oxides are acidic and which oxides are basic?
Acidic oxides typically contain nonmetals and react with water to form acids, such as sulfur dioxide (SO2) and nitrogen dioxide (NO2). Basic oxides contain metals and react with water to form bases, like sodium oxide (Na2O) and magnesium oxide (MgO).
What compounds does MgCO3 break into?
With sufficient heating, MgCO3 -> MgO + CO2, magnesium oxide and carbon dioxide.
What are the amphoteric oxides of mgo and zno?
The amphoteric oxides of MgO and ZnO can act as both acidic and basic compounds. MgO can react with both acids and bases to form salts, while ZnO can also exhibit similar behavior. These oxides can accept or donate protons depending on the conditions.
How can you test for magnesium oxide and carbon dioxide?
Carbon dioxide absorbed in water form carbonic acid, H2CO3; the pH become acidic and you can test the solution with a pH paper. A simple test for the magnesium oxide, MgO, is to measure the refractive index (this value is 1,736 for MgO.
When magnesium carbonate (MgCO3) decomposes it produces a metal oxide and a gas. Predict the products of this reaction?
MgCO3 --> MgO + CO2(g) Magnesium oxide and gaseous carbon dioxide
What is the chemical equation of magnesium burns in carbon dioxide to form magnesium oxide and carbon?
This equation is 2 Mg + CO2 -> 2 MgO + 2 C.
Is MgO an acidic or basic anhydride?
MgO is a basic anhydride because it reacts with water to form the base magnesium hydroxide.
What is the equation for thermal decomposition of magnesium carbonate?
The equation for the thermal decomposition of magnesium carbonate is: MgCO3(s) → MgO(s) + CO2(g). This reaction occurs when magnesium carbonate is heated, leading to the formation of magnesium oxide and carbon dioxide gas.
What is the reaction if MgCO3 is heated?
When MgCO3 (magnesium carbonate) is heated, it will decompose into magnesium oxide (MgO) and carbon dioxide (CO2) gas. This reaction is a decomposition reaction, where a single compound breaks down into two or more simpler substances.
What is the skeleton equation representing the heating of magnesium carbonate to produce solid magnesium oxide and carbon dioxide gas?
Fe + S -------> Fe + S . 8 8 8 8
What are the oxides that are basic?
Some common examples of basic oxides are calcium oxide (CaO), magnesium oxide (MgO), and sodium oxide (Na2O). These oxides react with water to form alkaline solutions.
Is MgO an acidic oxide?
No. Like the other oxides of alkaline earth metals, it is basic. MgO + H2O --> Mg(OH)2
