Strong base since it is completely soluble
Answer:
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are joint together by electrostatic interaction and ionic compound sodium chloride is formed.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive and both bonded atoms connected together through covalent bond.
Answer is: tomatoes is thousand (1000) times more acidic than water.
pH(tomato) = 4.00.
pH(water) = 7.00.
pH = -log[H⁺<span>].
</span>[H⁺] = 10∧(-pH); concentration of hydrogen ions.
[H⁺] = 10⁻⁴ M = 0.0001 M; tomato.
[H⁺] = 10⁻⁷ M = 0.0000001 M; water.
[H⁺](tomato) /[H⁺](water) = 0.0001 M ÷ 0.0000001 M.
[H⁺](tomato) /[H⁺](water) = 1000.
When,
[OH⁻] = 1.4 × 10⁻³
Then,
pOH = -log (1.4 × 10⁻³)
pOH = 2.85
Also,
pH + pOH = 14
So,
pH = 14 - 2.85
pH = 11.15
As pH is greater than 7, so the solution is Basic in Nature.
Calculating for concentration of [H⁺],
As,
pH = -log [H⁺]
Or,
11.15 = -log [H⁺]
Taking Antilog on both sides,
[H⁺] = 7.07 × 10⁻¹² M
Result:
A solution with a hydroxide ion concentration of 4.15 × 10⁻³<span> M is Basic and has a hydrogen ion concentration of </span><u>7.07 × 10⁻¹² M.</u>
Answer:
The correct answer is - A. It is the fastest way to reproduce.
Explanation:
Asexual reproduction is the mode of reproduction that does not alter the genes or genetic matter in the offspring and also does not involve the fusion of gametes.
It does not include the genetic variation as it is similar to the parent genetic or sequences. The fastest way to reproduce is asexual reproduction. There is no direct relation between the stability of the environment the asexual reproduction.
