How is stomach growling an example of a chemical reaction?
A gas is evolved as a product of a chemical reaction.
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.
How to do a chemical test to distinguish between zinc powder and lead carbonate?
One method would be to add an acid such as HCl to each sample, and collect the gas produced. The zinc will produce hydrogen gas, which is flammable, while the lead carbonate will produce carbon dioxide, which is not flammable. Thus, one can distinguish between the compounds depending on whether or not the gas evolved in the reaction ignites.
Can a chemical reaction occur during the electrolysis of water?
yes. hydrogen and oxygen gas will be evolved
How would you capture hydrogen from a chemical reaction of an acid and a metal?
The hydrogen in such a reaction can effectively be collected using an apparatus called the gas jar. THis can be done by fitting the reaction flask with cork and a delivery tube running from the reaction flask to the gas jar. As the reaction proceed, the hydrogen evolved will be collected in the gas jar.

What is the evolved gas from sodium carbonate reaction?
Carbon dioxide

What gas evolved in the test for nitrogen?
Ammonia NH3 Science-teacher
What could you observe when magnesium reacts with sulfuric acid?
Hydrogen gas is evolved from this reaction.

What does the glowing split test suggest about the identity of the gas evolved in manganese oxide?
It means the gas produced is oxygen.

When calcium metal is placed in water is added to water the gas evolved does not catch fire but the same gas on adding sodium metal cathches fire why'?
In both reactions hydrogen gas is released but heat evolved in the sodium reaction is bigger.
What is the effervescence test?
The formation of gas bubbles in a liquid during a reaction is called effervescence. It is the process of bubbling as gas escapes.
Why do metals like calcium float when they react with water?
calcium floats on wahter because the hydrogen gas evolved on reaction sticks to the walls of the container where reaction is taking place....
