Which type of reaction is 2Fe2O3+ 3C → 4Fe+ 3CO2?
3C(s) + 2Fe2O3 → 4Fe(s) + 3CO2 C. Double-replacement reactions 1.
What type of bond is formed between aluminum and sulfur?
Aluminum is metal, and sulfur is non-metal, so when they combine, an ionic compound is formed by transferring electrons from the metal to non-metal. Aluminum is in group 13, so each aluminum atom brings three valence electrons, while sulfur is in group 16, bringing six valence electrons.
What happens when aluminum metal combines with oxygen gas?
Aluminum metal reacts with oxygen gas to form solid aluminum oxide .
Is CaO a lime?
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. ... Calcium oxide that survives processing without reacting in building products such as cement is called free lime.
What is displacement reaction Class 11?
Displacement reaction is a chemical reaction in which one reactant present in the equation is displaced with the other reactant and owing to this phenomenon this reaction is also called the replacement reaction. ... Generally only one reactant undergoes the displacement process and replaces the ion in another reactant.
What is decomposition in Chem?
Definition. Decomposition is the breakdown or change of a material or substance (by heat, chemical reaction, or other processes) into other chemical compounds. Thermal decomposition is decomposition initiated by heating.
What is rancidity and corrosion?
This process is called corrosion. Rusting: Iron metal when left exposed, reacts with moisture and air and gets coated with a reddish-brown powdery substance called rust. This process is called rusting. Rancidity: Food containing fats and oil when exposed to air gets oxidized and gives a bad taste and smell to food .
