What is observed when copper oxide is added into excess dilute sulphuric acid?
When copper oxide is added into excess dilute sulphuric acid, it reacts to form copper sulfate and water. Additionally, hydrogen gas is evolved during the reaction.
What gas evolved when potassium nitrate crystals are heated with concentrated sulphuric acid?
When potassium nitrate crystals are heated with concentrated sulphuric acid, nitric oxide gas (NO) is evolved. This is a result of the oxidation of nitrate ions in potassium nitrate by the sulphuric acid.
What observations are made in the reaction of hexane and concentated sulphuric acid?
In the reaction of hexane with concentrated sulfuric acid, the acid acts as a dehydrating agent and can lead to the formation of alkyl sulfates and alkenes. The reaction may also produce some byproducts like water and sulfur dioxide gas. Heat is usually evolved during the reaction due to its exothermic nature.
What happens when zinc is treated with sulphuric acid?
When zinc is treated with sulfuric acid, hydrogen gas is evolved, forming zinc sulfate and water as products. This reaction is a displacement reaction where zinc replaces hydrogen in the sulfuric acid to form zinc sulfate.
What is the evolved gas from sodium carbonate reaction?
The evolved gas from the reaction of sodium carbonate is carbon dioxide (CO2).

What is the name or formula the gas evolved in heating of potassium chlorate?
The gas evolved in the heating of potassium chlorate is oxygen gas (O2). The chemical equation for this reaction is: 2KClO3 (s) -> 2KCl (s) + 3O2 (g)
What if sulfuric acid and sodium are mixed?
When Sulphuric acid and Sodium are mixed, Hydrogen gas is evolved which makes a pop sound when a burning splinter or candle is bought near it. The following reaction takes place: H2S04 + Na - NaSO4 + H2
What happens when zinc is treated with sulphuric acid?
When zinc is treated with sulfuric acid, hydrogen gas is evolved, forming zinc sulfate and water as products. This reaction is a displacement reaction where zinc replaces hydrogen in the sulfuric acid to form zinc sulfate.
What is the evolved gas from sodium carbonate reaction?
The evolved gas from the reaction of sodium carbonate is carbon dioxide (CO2).
What happens when dilute sulphuric acid is poured on a copper plate-?
It depends, if the susexphuri acid is of a high concentration and is hot, then the copper plate will react and dissolve. sex though it is not a strongly oxidizing acid, hot concentrated sulfuric acid is a strong enough oxidizing agent to dissolve copper.
What is the only thing that can get changed in a balancing equation?
It is the mass defect during a fission reaction. Enrgy evolved during a radioactive fission can be calculated using the formula gived by Einstein e =mc
How is stomach growling an example of a chemical reaction?
A gas is evolved as a product of a chemical reaction.
What is the gas evolved in the test for nitrogen write the equation involved?
In the test for nitrogen, nitrogen gas (N₂) is typically evolved when certain reactions occur, such as the decomposition of ammonium compounds or the reaction of nitrates with reducing agents. For example, when ammonium chloride (NH₄Cl) is heated, it can decompose to release nitrogen gas: [ 2 \text{NH}_4\text{Cl} \rightarrow \text{N}_2 + 2 \text{HCl} + \text{H}_2 ] This equation illustrates the release of nitrogen gas during the reaction.
How you call the starting substances that are evolved in a chemical reaction?
Reactants.
