Answer:

Atomic elements exist with a single atom as their basic unit.

H, F, and P are some examples of atomic elements.

H2, F2, and P4 are some examples of molecular elements.

Molecular elements have more than one atom in their basic unit.

Explanation:

Atomic element exists as the smallest particle of an element that can take part in a chemical reaction. They exist with a single atom as their basic unit. The atomic number of an element is the number of protons present in the atomic nucleus of the element. Atomic elements are usually monoatomic such as H, F and P.

Molecular elements are the smallest particle that are capable of independent existence and still retains the chemical properties of those substances. They are capable of independent existence because they are diatomic. The combination of atoms of the same type produces a molecule of an element such as H₂, F₂, and P₂.

For the diprotic weak acid h2a, ka1 = 3.2 × 10-6 and ka2 = 6.1 × 10-9. what is the ph of a 0.0650 m solution of h2a? what are th
Stolb23 [73]
Given:

Diprotic weak acid H2A:
 
Ka1 = 3.2 x 10^-6
Ka2 = 6.1 x 10^-9. 
Concentration = 0.0650 m 

Balanced chemical equation:

H2A ===> 2H+  + A2- 
0.0650       0        0
-x                2x       x
------------------------------
0.065 - x     2x      x

ka1 = 3.2 x 10^-6 = [2x]^2 * [x] / (0.065 - x)

solve for x and determine the concentration at equilibrium.

Boiling occurs when molecules being changed from liquid to gas plz tell me the answer true or false
Valentin [98]

Answer:

Liquid to Gas

Explanation:

The particles need energy to rise and over come the attractions between them as the liquid gets warmer more particles have sufficient, energy to escape from liquid. eventually even particles in the middle of the liquid form bubbles of gas in the liquid At this point the liquid is boiliing and turning into gas.

What happens in the redox reaction below? Select all that apply.
vladimir2022 [97]

Answer:

B- Sodium loses an electron.

D- Fluorine gains an electron.

Sodium is oxidized.

Explanation:

The reaction equation is given as:

        Na  + F →  NaF

In this reaction, Na is the reducing agent. It loses an electron and then becomes oxidized. By so doing, Na becomes isoelectronic with Neon.

Fluorine gains the electron and then becomes reduced. This makes fluorine also isoelectronic with Neon.

This separation of charges on the two species leads to an electrostatic attraction which forms the ionic bonds.
