How could a sample gas be collected at the positive electrode when using electrolysis for copper?
Place an inverted test tube over the elctrode
What test can be carried our to confirm the presence of sodium gas in electrolysis?
Electrochemistry is the test that can be carried to confirm the presence of sodium gas in electrolysis.
What is the reaction equation of electrolysis of water with copper electrodes?
The electrolysis of water produces oxygen and hydrogen gas. 2H2O --> 2H2 + O2
Write the balanced equation for the electrolysis of water. What type of reaction is this?
water itself is not a good electrolyte its electrolysis is performed in presence of anacid usually sulphuric acid, on electrolysis water produces hydrogen and oxygen gas. 2H2O = 2H2 + O2
Can carbon monoxide gas collected by downward displacement of water?
No,it can't be collected
Why is double the amount of gas collected in one of the test tube on electrolysis of water name the gas?
Water contains two parts hydrogen and one part oxygen (2 H and 1 O = H2O) Because of this, the amount of hydrogen and oxygen produced during electrolysis of water is in a 2:1 ratio. In electrolysis process, hydrogen goes to one test tube and oxygen goes to another. Because Water contains 2 part hydrogen, the amount of gas collected in one tube is double the amount collected in the other.

Electrochemistry is the test that can be carried to confirm the presence of sodium gas in electrolysis.
Why is the volume of gas collected twice of the volume of other gas when electric current is passed through water?
When an electric current is passed through water, it undergoes electrolysis, which breaks water molecules into hydrogen and oxygen gases. The ratio of hydrogen to oxygen gas produced is 2:1, meaning that for every two volumes of hydrogen gas collected, one volume of oxygen gas is collected. Therefore, the volume of gas collected is twice as much for hydrogen compared to oxygen gas.
What is the reaction equation of electrolysis of water with copper electrodes?
The electrolysis of water produces oxygen and hydrogen gas. 2H2O --> 2H2 + O2
What are the example of endothermic?
Electrolysis of water to oxygen and hydrogen gas
What are the changes of endothermic?
Electrolysis of water to oxygen and hydrogen gas
How can you decompose?
Electrolysis, by passing a spark through water to form hydrogen and oxygen gas. Electrolysis, by passing a spark through water to form hydrogen and oxygen gas. and heating is also a method.
What are the products when water is broken down by electrolysis?
The two products when water is broken down by electrolysis is hydrogen gas and oxygen gas. The energy source in photosynthesis is light energy.

What is the breakdown of water into hydrogen to oxygen is an example of?
Electrolysis. The breakdown of water into oxygen and hydrogen gas.
