Answer:

2.951 × 10⁻⁵ M

Explanation:

Let's consider the acid reaction of hydrobromic acid according to Brönsted-Lowry acid-base theory.

HBr(aq) + H₂O(l) ⇒ Br⁻(aq) + H₃O⁺(aq)

Given the pH = 4.530, we can calculate the concentration of the hydronium ion using the following expression.

pH = -log [H₃O⁺]

[H₃O⁺] = antilog -pH = antilog -4.530 = 2.951 × 10⁻⁵ M

How are radioisotopes different from the standard form of an element

meriva

Answer:

Different isotopes of the same element have the same number of protons in their atomic nuclei but differing numbers of neutrons. Radioisotopes are radioactive isotopes of an element. They can also be defined as atoms that contain an unstable combination of neutrons and protons, or excess energy in their nucleus.

Give the number of protons and electrons in each of these ions or atoms (show your work) Cs. Ba , .s

Morgarella [4.7K]

Explanation:

The sum of total number of protons present in an element is known as atomic number of the element.

As atomic number of Cs is 55.

And, it is known that for a neutral atom the number of protons equal to the number of electrons.

Since, no charge in present on given Cs atom it means that it is neutral in nature. Hence, number of protons and electrons present in Cs are 55.

For Ba, it is also neutral in nature and atomic number of barium is 56. Hence, number of protons and electrons present in Ba are 56.

For S, there is no charge on it so it is also neutral in nature. Atomic number of S is 16. Hence, number of protons and electrons present in S are 16.

what is the structure of XeO2F2???i know its hybridization as sp3d but cannot quite understand its diagram in free space,help an

skelet666 [1.2K]

The shape of XeO₂F₂ is Trigonal bi-pyramidal see-saw tetrahedron (see attached pictures)
- As you said the hybridization of Xe here is sp³d so its geometry has to be Trigonal bi-pyramidal in which F atom located on axial positions but for the final shape we exclude lone pair on Xe to give see-saw shape (see second picture)
- Remember that we have 5 pairs (4 bond pairs + 1 lone pair) and we have to place lone pair at equatorial position.
