<h3><u>Answer;</u></h3>
C → CO₂ + 4e₋
O₂ + 4e₋→ CO₂
<h3><u>Explanation</u>;</h3>
- Given the reaction C + O2 ---> CO2
- During the formation of a carbon dioxide molecule, the carbon atom shares four electrons with the oxygen atom on the left and four electrons with the oxygen atom on the right.
- This means there will be eight electrons around each atom. Two pairs of electrons shared between two atoms make a double bond between the atoms, which is represented by a double dash.
Answer: A) weak acid.
Explanation: The strength of an acid or base depends on the degree of ionization in water, the graph shows the ionization of a weak acid.
A strong acid ionizes completely in solution producing excess hydroxonium ions.
A strong base also ionizes to produce excess hydroxyl ions in solutions.
A weak acid does not ionize completely in solutions
A weak base does not ionize completely in solutions.
HA shown in the graph is an acid because as we can see it produces hydroxonium ions in solutions. A base will produce hydroxyl ions.
