What is the gas evolved in heated potassium chlorate?
Oxygen gas is evolved when potassium chlorate is heated. The thermal decomposition of potassium chlorate releases oxygen gas, leaving behind potassium chloride as a residue. This reaction is commonly used in oxygen-generating experiments and processes.
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.
Which gas is evolved when iron reacts with sulphuric acid write the word equation evolved how will you didcate for the gas evolved in the reaction?
When iron reacts with sulfuric acid, hydrogen gas is evolved. The word equation for this reaction is: Iron + Sulfuric acid -> Iron sulfate + Hydrogen gas. To indicate the gas evolved in the reaction, one can place a downward arrow (↓) next to the hydrogen gas in the products.
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.
How does potassium react with water?
It only creates a purple "cloud" as was stated in the previous answer when phenolphthalein is added to the water. The "cloud" is not a cloud. Hydrogen gas is evolved. Phenolphthalein is clear in acidic conditions, and purple in basic conditions. As potassium is added to the water, potassium hydroxide is created (alkaline/basic) therefore creating the purple colour water, and hydrogen gas is evolved. A link accompanying this shows lithium through to Caesium, potassium included, in water and shows the equation of the reaction. Caesium in particular is very entertaining.
Which gas is evolved when potassium ferrocyanide crystals are heated with conc. sulphuric acid?
When potassium ferrocyanide crystals are heated with concentrated sulfuric acid, the gas evolved is hydrogen cyanide (HCN). This gas is toxic and should be handled with caution in a well-ventilated area.
What gas is evolved when a few crystals of potassium nitrate are heated in a hard glass test tube?
Nitrogen dioxide and oxygen are released.
What is the gas evolved in heated potassium chlorate?
Oxygen gas is evolved when potassium chlorate is heated. The thermal decomposition of potassium chlorate releases oxygen gas, leaving behind potassium chloride as a residue. This reaction is commonly used in oxygen-generating experiments and processes.
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)
If a piece of potassium metal is dropped in water then a vigorous reaction takes place with the formation of potassium hydroxide and hydrogen gas is evolved?
Yes, it is correct.
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 happens in the coke and salt experiment?
Salt crystals are nucleation centers for carbon dioxide and this gas is violently evolved.
How was the flood created in Halo Combat Evolved?
it was from a biochemical disaster when hydrogen, potassium, and chlorine is combined and you inject it in to a slug!
What gas does Potassium permanganate give off when it is cracked and turned black?
Oxygen gas in evolved. 2KMnO4 ---> K2MnO4 + MnO2(s) + O2
What is the importance of center of mass?
Its evolved as a useful and time saving tool, and represents the mass if it were concentrated at a single point and especially useful when calculating motions of masses involved with the equations of motion.
