Beginning or Start
Explanation:
Reactions can be followed by measuring changes in concentration, mass and volume of reactants or products. The rate is highest at the start of the reaction because the concentration of reactants is highest at this point.

The Lewis structure of Carbonic Acid (H₂CO₃) is given below. In structure it is shown that carbon has a double bond with one oxygen atom and two single bonds with hydroxyl groups.
Formal Charge; Formal charge is caculated as,
Formal charge = # of valence e⁻ - [# of lone pair of e⁻ + 1/2 # of bonded e⁻]
Formal charge on Carbon;Formal charge = 4 - [ 0 + 8/2]
Formal charge = 4 - [4]
Formal charge = Zero
We use acids and bases in everyday life for cooking and cleaning
Answer:
See below
Explanation:
The atmosphere of the earth hundreds of millions of years ago was only water vapour and carbon, both from the one ocean that existed around the continental body of Pangea. The photosynthesis process and exache (⊕) caused the percentages to decrease.
