Scientists collected evidence to form a valid theory about the formation and early development of the solar system include:
- Stars forming the depths of giant clouds of gas and dust.
- Young stars with disks of debris around them.
<h3>
What is Solar system?</h3>
This is referred to the gravitationally bound system of the Sun and the objects that orbit it.
It also comprises of the planets and their moons and objects such as asteroids and the evidence which shows that the formation of the solar system are the gas and dust which form the stars and debris found around them.
This therefore makes it the evidence collected in the formation of the solar system mentioned the most appropriate choice.

Answer:
Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.

PH is simply a convenient way to denote hydronium ion concentration (usually in moles per liter or molarity). pH is calculated from the given concentration using the equation: pH = -log [H3O⁺]
To find [H3O+] from the given equation, we apply the antilog.
[H3O⁺] = 10⁻⁽pH⁾ or ten raised to the negative value of pH
A solution with a pH of 3.43 has a hydrogen ion concentration of 3.7154x10^-4 moles per liter.
Because anymore water will breakdown the bonds of your Oh groups
Thank you :))) for the points have a great day
