What is copper metal heated with oxygen gives solid copper II oxide classified as?
This is a chemical reaction known as oxidation, where copper metal undergoes a reaction with oxygen to form a new compound, which is solid copper II oxide.
When an acid reacts with metal the liquid changes colour to green?
There may be a misunderstanding. When an acid reacts with a metal, the metal usually undergoes a displacement reaction to form a salt and hydrogen gas. The color change to green may be due to impurities in either the acid or the metal, but it is not a typical result of the reaction between an acid and a metal.
What is happening when a metal molecule releases energy?
When a metal molecule releases energy, it is undergoing a process called exothermic reaction. This means that the molecule is releasing heat or light energy as it undergoes a chemical change.
What happens when metal and acid?
Acid + Metal = Salt + Hydrogen
What is the reaction of aluminium lead chloride?
When aluminum reacts with lead(II) chloride (PbCl2), it undergoes a single-replacement reaction. The aluminum displaces the lead to form aluminum chloride (AlCl3) and lead metal (Pb) as products. The balanced chemical equation for this reaction is: 2Al + 3PbCl2 → 2AlCl3 + 3Pb.
What type of reaction is occurring when a metal undergoes corrosion?
Corrosion of a metal is an electrochemical reaction where the metal undergoes oxidation, leading to the formation of metal oxides or other compounds. This process is typically accelerated in the presence of moisture or salts in the environment.
What change undergoes chemical change?
For example a chemical reaction with an alkali metal.
What kind of reaction is metal oxide metal oxygen?
The reaction between a metal and oxygen to form a metal oxide is typically an oxidation-reduction (redox) reaction. In this process, the metal undergoes oxidation as it loses electrons, while oxygen is reduced as it gains electrons. This type of reaction is exothermic, often releasing heat and light, and is fundamental in various applications, including combustion and rusting.

Explain why hydrogen gas is given off when a reactive metal undergoes a single-displacement reaction with water?
In a single-displacement reaction between a metal and water, the metal displaces hydrogen from water molecules. This results in the formation of metal hydroxide and hydrogen gas as a byproduct. The reactivity of the metal determines the amount of hydrogen gas produced during the reaction.
What type of a reaction occurs when potassium metal reacts with fluorine gas?
When potassium metal reacts with fluorine gas, it undergoes a redox reaction to form potassium fluoride. The potassium metal loses an electron to form a potassium cation, and the fluorine gas gains an electron to form fluoride anions. This reaction is highly exothermic and produces a white solid as the product.
What is the reaction of metallic oxide with water?
Reaction of a metal oxide with water produces a metal hydroxide, which is a strong base
What is happening when a metal molecule releases energy?
When a metal molecule releases energy, it is undergoing a process called exothermic reaction. This means that the molecule is releasing heat or light energy as it undergoes a chemical change.
What happen to a metal when exposed to an acidic mixture after one day?
When a metal is exposed to an acidic mixture for one day, it typically undergoes a chemical reaction known as corrosion. The acid can react with the metal, leading to the formation of metal salts and hydrogen gas, which may cause the metal to deteriorate or dissolve. The extent of this reaction depends on the type of metal and the concentration of the acid. Over time, this can result in pitting, structural weakening, or complete dissolution of the metal.
What is thesymbol of black none metal formed when toast is burnt?
The symbol for carbon, a black non-metal, is C. When toast is burnt, the carbon in the bread undergoes a chemical reaction known as combustion, resulting in the blackened appearance.
What happens when metal and acid?
Acid + Metal = Salt + Hydrogen
