What else can I help you with?
What is the sign in a chemical reaction that a gas has been produced?
You can see the release of this gas.
What do you see when heating a cupric nitrate?
Yes you can see a reaction. It emits Nitrogen dioxide gas
What cause the effervescence during the reaction of HCl and Zinc?
Zn + 2HCl -> ZnCl2 + H2 As you can see it is the hydrogen gas released in this reaction, which causes the effervescence. Just to note, in any reaction between a reactive metal and an acid, hydrogen gas is always produced.
How could you test the gas released in reaction 6 to confirm its indentity?
To confirm the identity of the gas released in reaction 6, you could perform tests such as the pop test (putting a lit splint near the gas to see if it ignites with a pop), the limewater test (passing the gas through limewater to see if it turns milky, indicating the presence of carbon dioxide), or using a gas sensor to analyze the chemical composition of the gas.
What is the role of a manganese in a reaction?
See for the biological role at: http://en.wikipedia.org/wiki/Manganese.
If you see bubbles what is being made?
i think a gas is being made but not entirly sure :)
What is the reaction when zinc reacts with sulphuric acid?
We can see bubbles of gas being released. The gas is a new substance, so this is evidence that a chemical reaction is taking place. the gas released during this reaction is hydrogen.

How can you tell if the reaction of calcium carbonate and hydrochloric acid is finished?
You can tell if the reaction is finished when there are no more bubbles of gas being produced. This indicates that all the calcium carbonate has reacted with the hydrochloric acid. You can also test by adding a few more drops of hydrochloric acid to see if any additional bubbles are produced.
When baking soda is added to an acid why does it fizz?
When baking soda (sodium bicarbonate) is added to an acid, a chemical reaction occurs that produces carbon dioxide gas. The fizzing you see is the visible evidence of this gas being released. This reaction can be represented by the following equation: NaHCO3 + H+ → Na+ + CO2 + H2O.
How can you tell when a gas is given off in an experiment with lime stone and hydrochloric acid?
I dont hav a bloody clu...ANS2:Well, if you were to happen to watch the reaction, you would see bubbles rise in the solution. If you were apt, seeing bubbles would be your clue that gas is produced.
What compound is made from sodium carbonate and hydrochloric acid?
Let's see. Na2CO3 + 2HCl -> 2NaCl + CO2 + H2O Table salt, carbon dioxide gas and water are the products of this reaction.
What cause the effervescence during the reaction of HCl and Zinc?
Zn + 2HCl -> ZnCl2 + H2 As you can see it is the hydrogen gas released in this reaction, which causes the effervescence. Just to note, in any reaction between a reactive metal and an acid, hydrogen gas is always produced.
Why do some things fizz when you put it in water?
When an effervescent reaction occurs, such as with Alka-Seltzer tablets or soda pop, it's due to a chemical reaction between the substance and water that releases carbon dioxide gas. The fizz you see is the gas escaping from the liquid.
How could you test the gas released in reaction 6 to confirm its indentity?
To confirm the identity of the gas released in reaction 6, you could perform tests such as the pop test (putting a lit splint near the gas to see if it ignites with a pop), the limewater test (passing the gas through limewater to see if it turns milky, indicating the presence of carbon dioxide), or using a gas sensor to analyze the chemical composition of the gas.
What are two character characteristics that a chemical reaction is made?
If you have a chemical reaction you will generally see at least one of the following; a colour change (like iron rusting and going orange), a gas being produced (fizzing or bubbling), heat being generated (like plaster of Paris setting) or being used up so it gets cold. These are the changes that most chemistry classes want you to talk about.Of course, a chemical reaction can produce other types of energy. Fireflies use a chemical reaction to produce light (much like glow sticks). Sometimes it's just a change in texture - like most cooking makes.
