The balanced net iconic equation :
- (a) 2HNO3 (aq) Ba(OH)2 (aq) Ba(NO3) (aq) + 2H20
- (b) HF(aq) + K+(aq) + OH-(aq) → K+(aq) + F-(aq) + H2O(l) Net: HF(aq) + OH-(aq) → H2O(l) + F-(aq)
- (c) C6H5NH2 + HClO4 → ClC6N + 4H2O
<h3>Briefing :</h3>
Salt and water are created when an acid and a base interact then Acid-based reaction happens. Because both water and salt are neutral, if an acid and a base react together, they cancel out each other's effects. It is referred to as a neutralization reaction as a result.
<h3>What is acid-base reaction?</h3>
An acid-base reaction is a chemical reaction involving an acid and a base.
H+ and OH- ions are produced by bases and acids, respectively, and these ions combine to make water. There are a number of drawbacks to the Arrhenius theory. Because it defines acids and bases in terms of what occurs when compounds dissolve in water, it can only be applied to reactions that take place there.
One or more hydrogen ions, H+, are exchanged between entities that may be neutral (such as H2O) or electrically charged (ions-ammonium, NH4+; hydroxide, OH; or carbonate, CO32); in an acid-base process.

The solubility of Ca(OH)2 in a 0.469M CaCl2 solution at 31°C, at given Ksp of Ca(OH)2 is determined as 1.626 mM.
<h3>
Dissociation reaction of Ca(OH)2</h3>
The dissociation reaction of Ca(OH)2 is given as follows;
Ca(OH)₂ ⇄ Ca²⁺ + 2OH⁻¹
x 2x
Concentration of Ca²⁺ = 0.469 M
Ksp = [x][2x]²
ksp = (0.469)(2x²)
ksp = 4(0.469)x²
ksp = 1.876x²
4.96 x 10⁻⁶ = 1.876x²
x² = (4.96 x 10⁻⁶)/(1.876)
x² = 2.643 x 10⁻⁶
x = √(2.643 x 10⁻⁶)
x = 1.626 x 10⁻³ M
x = 1.626 mM
Thus, the solubility of Ca(OH)2 in a 0.469M CaCl2 solution at 31°C, at given Ksp of Ca(OH)2 is determined as 1.626 mM.

Answer:
6 elements which are carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus
Explanation:
Living organisms are made up of various unit of giant organic molecules that have been produced through life processes.
The bulk of elements that makes up living organisms are carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus.
Carbon is almost present everywhere in living organisms. It's unique ability to form a key component lies on its bond formation capabilities. Carbon is found in nearly all organic molecules like carbohydrates, proteins, fats and oils, e.t.c
Hydrogen like carbon is key to life. It is light and making it form different bond types with carbon. It is one of the atoms that makes up water.
Nitrogen is usually found in proteins. They are unique elements that life cannot do without.
Oxygen is useful in respiration processes and it is the bedrock through which energy is released from glucose.
Sulfur is key to life.
Phosphorus in Adenosine Diphosphate is a good store of energy.
The answer is (2) low temperature and high pressure so oxygen gas behave least like an ideal gas :)))

Answer (3) is the most correct, although (2) is not to be ignored. (3) states the most abundant isotope Ti's average mass, which is certainly true. (2) is the total mass of all protons, neutrons, and electrons in an atom of Ti, which is true but has to be more specific in order to pinpoint exactly the 47.88 amu. (4) is incorrect because it is not of all the naturally occurring isotopes of Ti. (1) is incorrect because they forgot electrons.
