Decompose water with electrolysis, hydrogen gas and oxygen gas is formed. React water with sodium metal, hydrogen gas is formed. React magnesium metal with any acid, hydrogen gas is formed. React hydrochloric acid with calcium carbonate, carbon dioxide gas is formed.

Why will there be air bubbles forming when water is being heated?
As the flask expands,hor air is being pushed out,therefore,air bubbles are formed.
What does the reaction between hydrochloric acid and calcium carbonate look like?
It will produce calcium chloride, water and carbon dioxide gas. You will observe bubbles of carbon dioxide gas being produced.
What substance is being produced at the end of translation?
googonana
How to test oxygen?
What do you mean? To test for oxygen being produced, light a splint, blow it out then put it over the object you beleve is producing oxygen and if the splint re-lights oxygen is being produced.
What is an example of a mixture?
To be a mixture, the substances comprising the mixture must be capable of being physically separated out, rather than chemically combined. Some examples of mixtures are:AirFogCinnamon sugarBronze and other metal alloysMilkSaltwater is also an example of a mixture, and is easily separated by evaporation.
What is being produced when bubbles are present during a chemical reaction?
a gas
What if your pondweed experiment had only a few big bubbles?
Less oxygen is being produced at a slower rate
How is the number of bubbles produced by the plant related to the rate of photosynthesis?
One of the products of Photosynthesis is oxygen (Carbon Dioxide and Water give Glucose and Oxygen) and the bubbles you see coming from pond weed are actually the oxygen being produced from Photosynthesis. So therefore, the more/faster the bubbles, the quicker Photosynthesis is happening.
Is formation of bubbles a physical change?
If you ae talking bubbles released from a can of soda = physical. It is just carbon dioxide being released. If you are talking bubbles produced from a mixture of baking soda and vinegar = chemical. It is actually changing the chemical composition and releasing oxygen from the H2O.
What happens to the oxygen produced by plants during photosynthesis when the plant lives in water?
Some of the oxygen will dissolve in the water and some will escape into the atmosphere. On a sunny day you can often see bubbles being produced by algae in ponds.
What is the best description of mechanical energy type source?
related to or produced by a machine and/or gravitational and kinetic forces, two examples being rollup doors and fansrelated to or produced by a machine and/or gravitational and kinetic forces, two examples being rollup doors and fans
Why would bubbles appear if an acid were poured on chalk?
Chalk is calcium carbonate, CaCO3 and acid contains H+. So, using HCl as an example of the acid being used, the chemical reaction would be CaCO3 + 2HCl ==> CaCl2 + CO2 + H2O and the bubbles are formed by the CO2 (carbon dioxide) gas being produced.
Why will there be air bubbles forming when water is being heated?
As the flask expands,hor air is being pushed out,therefore,air bubbles are formed.
What do the bubbles represent?
Bubbles represent a cool, happy, bubbly personality. It represents being comfortable with your self and being very comfortable in your personality
What does the reaction between hydrochloric acid and calcium carbonate look like?

Why are Winchester rifles not being produced?
They are being produced.
What do you see when a gas is being made in a reaction?
bubbles
