When a liquid goes from a liquid state to a gaseous state it is called evaporation
Answer:
The combination of oxygen with other substances to produce new chemical products is called <u>Oxidation</u>.
Explanation:
Oxidation reactions are defined as,
In terms of Inorganic chemistry:
(i) <u>Removal of Electrons: </u>
Example: Mg → Mg²⁺ + 2 e⁻
(ii) <u>Addition of Oxygen:</u>
Example: 2 Mg + O₂ → 2 MgO
In terms of Organic chemistry:
(i) <u>Addition of Electrons: </u>
Example: Cl₂ + 2 e⁻ → 2 Cl⁻
(ii) <u>Addition of Hydrogen:</u>
Example: H₂CCH₂ + H₂ → H₃CCH₃

Answer: 12.78ml
Explanation:
Given that:
Volume of KOH Vb = ?
Concentration of KOH Cb = 0.149 m
Volume of HBr Va = 17.0 ml
Concentration of HBr Ca = 0.112 m
The equation is as follows
HBr(aq) + KOH(aq) --> KBr(aq) + H2O(l)
and the mole ratio of HBr to KOH is 1:1 (Na, Number of moles of HBr is 1; while Nb, number of moles of KOH is 1)
Then, to get the volume of a 0.149 m potassium hydroxide solution Vb, apply the formula (Ca x Va)/(Cb x Vb) = Na/Nb
(0.112 x 17.0)/(0.149 x Vb) = 1/1
(1.904)/(0.149Vb) = 1/1
cross multiply
1.904 x 1 = 0.149Vb x 1
1.904 = 0.149Vb
divide both sides by 0.149
1.904/0.149 = 0.149Vb/0.149
12.78ml = Vb
Thus, 12.78 ml of potassium hydroxide solution is required.
