Which gas is evolved when KMnO4 reacts with H2C2O4?
The evolved gas is carbon dioxide (CO2).
What heat gas production and color change can all be evidence of chemical change.?
- A gas is evolved from reactants only if a chemical reaction occured.- The same situation for the color change.These are very possible signs but they are not absolute; many other factors must be studied.
Which gas is evolved during photosynthesis?
Oxygen gas is evolved during photosynthesis as a byproduct of the light-dependent reactions in the chloroplasts of plant cells.
What is the test for the gas evolved when sodium hydrogen carbonate is added to acetic acid?
The gas evolved is carbon dioxide. The test is that it turns lime water milky.
What is the chemical formula for nirtrogen gas?
Formula: N2
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)
When lead nitrate is heated which colour fumes are evolved?
When lead nitrate is heated, brown nitrogen dioxide gas is evolved, which gives off a yellowish-brown color.
What are the six types of evidence for a chemical change?
Types of evidence for chemical change include: A gas is evolved. A precipitate appears or disappears. Heat may be evolved or absorbed. A color change occurs. A substance disappears.

The evolved gas is carbon dioxide (CO2).
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 is the gas evolved at anode during electrolysis of aqueous NaCl?
Chlorine gas is evolved at the anode during the electrolysis of aqueous sodium chloride (NaCl) because chloride ions are oxidized to form chlorine gas.
What gas is evolved when acetone-bisulfite with HCl?
When acetone bisulfite reacts with HCl, sulfur dioxide gas is evolved.
What is the evolved gas from sodium carbonate reaction?
The evolved gas from the reaction of sodium carbonate is carbon dioxide (CO2).
What the name of he gas evolved when baking soda reacts with dilute hydrochloric acid?
Hydrogen gas- very explosive when mixed with a spark
Which gas is evolved when carbonates are treated with acid?
Carbon dioxide gas, CO2(gas)
