What is the pH of a solution that has [H+] of .0042M?

Chemistry
1 answer:
sveticcg [70]2 years ago
8 0

Answer:

pH = 2.4

Explanation:

pH is defined as the negative log of the hydronium concentration.

Thus, we can plug in the given hydronium concentration:

pH = -log[H⁺] = -log[0.0042] = 2.4 (two significant figures)

The pH of the solution is 2.4.

P.S: Although I referred to [H⁺] as hydronium concentration, it is more accurate to express it as [H₃O⁺], though they are interchangeable and means the same thing.

Which of the following statements is TRUE? (A) An ionic bond is much stronger than most covalent bonds.(B) Once dissolved in wat
Ainat [17]

Answer:

A)  An ionic bond is much stronger than most covalent bonds.

Explanation:

D) Ionic compounds have high melting points causing them to be solid at room temperature, and conduct electricity when dissolved in water. Covalent compounds have low melting points and many are liquids or gases at room temperature.

C) An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.

A) Covalent bonds are stronger if you compare with ionic molecules, because their molecular orbital overlap is bigger. However, ionic molecules form lattices, thus the energy to break this lattice bond is stronger hence the ionic bond is stronger.

ccording to all known laws of aviation, there is no way a bee should be able to fly. Its wings are too small to get its fat litt
drek231 [11]

Answer:

The bee's energy output can be calculated directly, and related to its size. it only needs enough air resistance to counter its weight and enough power in its wings to sustain this resistance. it bee like that.
