Answer:
The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
Explanation:
You should first draw a diagram to show all the process occur in water cycle
Evaporation: The water from the rivers rises in the form of vapours and reaches up to the cloudes.
Precipitation: The water stored inside clouds and pour water to the earth in the form of rainfall.
Then this water reaches inside soil which help plants to grow and develop and also help in achieveing nutrients and minerals which enhance their respiration process.
After this water loss due to transpiration in plants vapours again and from the rivers also to continue this nature cycle known as Water Cycle.
For Chlorine, CI
The protons and electrons will be the same except Protons will be + positive and electrons will be - negative so your answers are 17 and -17
neutrons is 18
atomic number 17
Atomic mass: 35.453
For sodium, Na
The protons and electrons will be the same except Protons will be + positive and electrons will be - negative your answers are 11 and -11
neutrons : 12
atomic number: 11
Atomic mass: 22.9897
hope this helps good luck
