In order for us to have water to drink, it first needs to go through a process called the water cycle. And in that water cycle there’s a process called evaporation. Evaporation is the process by which water changes from a liquid to a gas. In order for it to rain we need clouds and clouds are made of water. The water is heated causing water molecules to convert into gas, that gas then goes through a process called condensation creating clouds. At some point those clouds will be full of water, and all that water will then cause the cloud to release the water molecules causing rain.
Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.
<h3>What is a separation technique?</h3>
A separation technique can be defined as a technique that is used to separate (convert) two or more mixture and solution of chemical substances into distinct products such as solutes, chemical compounds or elements.
<h3>What is a chemical element?</h3>
A chemical element can be defined as a pure substance which comprises atoms that have the same atomic number (number of protons) in its nuclei and as such it is the primary constituent of matter.
Generally, some examples of a chemical element include the following:
In Chemistry, sodium hydroxide, caustic soda, or lye all refer to the same chemical compound which is represented by this chemical symbol, NaOH.
According to the narration, Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.

The scientific method has five basic steps, plus one feedback step: Make an observation. Ask a question. Form a hypothesis, or testable explanation.
Answer:
It equals to the number of electrons in that atom, which is in turn equal to its atomic number

What are the two oxidation states of sulphur in sodium thiosulphate ? In thiosulphate, two sulphurs have oxidation state of -2 and +6. (as per suggestions). Sulphur bonded to three oxygen is considered to have +6 (Sulphur A) and other sulphur has -2 (Sulphur B).
