Answer:

Yes.

Explanation:

Hello,

As long as it shows important relationships between the size and color of stars, age wouldn't affect observation and measurement but will just provide more accurate results but the method is still valid.

Best regards.

The electron configurations of two unknown elements X and Y are shown.

Svetllana [295]

X: 1S²2S²2P⁶

Y: 1S²2S²2P⁶3S²3P⁶

The statement which is most likely correct about the two elements is

They will not react because both have a complete outermost shell and are stable.

Explanation

The P orbital can hold a maximum of 6 electrons,therefore the 2P orbital for x and 3P orbital for Y which are outermost subshell are fully filled .

This make element Y and x stable since they cannot react either by gaining or losing electrons.

Given a chemical equation, showing the dissociation of an acid in solution, be able to identify the "acid", the "base", the "con

Karo-lina-s [1.5K]

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory:

An acid is defined as a substance which looses donates protons and thus forming conjugate base
A base is defined as a substance which accepts protons and thus forming conjugate acid.

$HA+H_2O\rightarrow A^-+H_3O^+$

Suppose acid Ha is getting dissociated in its solution and after dissociation it donates its proton to water molecule and forms conjugate base. Where as water (acting as a base) accepts protons and forms conjugate acid.

HA = Acid

$H_2O$ = Base
