Do ionic bonds increase the stability of atoms

Chemistry
1 answer:
marysya [2.9K]3 years ago
8 0
The stability of atoms depends on whether or not their outer-most shell is filled with electrons. If the outer shell is filled, the atom is stable. ... In ionic bonds, atoms donate or receive electrons to achieve stability. In covalent bonds, atoms share electrons to achieve stability.

Thus, ionic bonds increase the stability of atoms

10.30 Indicate whether each of the following solutions is acidic,
goldfiish [28.3K]

Answer:

Basic

Explanation:

The pH scale is measured from 0 to 14.

At the pH scale of 7, a solution is neutral.

Any solution above 7 is basic.

Any solution below 7 is acidic.

Because you have been given the hydronium concentration [H₃O⁺], you can find the pH of the solution using the following formula:

pH = -log[H₃O⁺]

pH = -log(6.0 x 10⁻¹²)

pH = 11.22

As you can see, the solution must be basic because the pH lies within the basic range.

The formula for acetic acid is CH3COOH. Seana wants to know how many oxygen atoms are in 0.12 moles of acetic acid. O a. 1x 10^2
MA_775_DIABLO [31]

Answer:

c. 1.4 x 10²³ oxygen atoms

Explanation:

The number of oxygen atoms in one molecule of CH₃COOH is 2.

Avogadro's constant relates the number of molecules in one mole:

6.022 × 10²³ mol⁻¹

Thus, the number of oxygen atoms in one molecule of acetic acid can be converted to the number of oxygen atoms in one mole of acetic acid:

(2 oxygen atoms / molecule)(6.022 × 10²³ molecule / mol) = 1.204 x 10²⁴ atoms per mole

Finally, the number of oxygen atoms in 0.12 moles of acetic acid are calculated:

(1.204 x 10²⁴ atoms / mol)(0.12 mol) = 1.4 x 10²³ atoms/mol
