Answer:

Plasma

Explanation:

Plasma is a state of matter that in some cases is a synonym of ionized gas. It consists of groups of ions (particles with a net charge) with some of their outer electrons removed.

How many electrons have been removed depends on the type of plasma, since the most energetic plasmas are completely free of orbiting electrons. This is the case of the interiors of the sun and other stars.

<h3>Answer:</h3>

12 neutrons

<h3>Explanation:</h3>
  • A neutral atom is an atom that has no charge, which means it has no additional electrons or electrons removed from its energy levels.
  • An atom is made up of sub-atomic particles neutrons and protons found in the nucleus and electrons found in the energy levels.
  • The number of protons in the nucleus of a neutral atom is known as the atomic number.
  • In a neutral atom, the atomic number is equal to the number of electrons as protons are equal to the number of electrons.
  • The sum of protons and neutrons in the nucleus of an atom is known as the mass number of an atom.

Therefore;

Protons = Atomic number

Protons + neutrons = Mass number

Thus;

Neutrons = Mass number - protons or

                = Mass number - atomic number

In this case;

Atomic number = 11

Mass number = 23

Thus;

Neutrons = mass number - atomic number

               = 23 - 11

              = 12 neutrons

Hi my dear friend,

Because we must add heat, boiling water is a process that chemists call endothermic. Clearly, if some processes require heat, others must give off heat when they take place. ... Changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing.

~Thank you

Tema [17]

Answer:

see below

Explanation:

Aqueous hydroiodic acid reacts with liquid water in a reversible reaction.

2 HI  +  2 H₂O  ⇔  2 H₃O  +  I₂

This is an acid-base reaction.  HI is the acid, and H₂O is the base.  The conjugate acid is H₃O, and the conjugate base is I₂.  You can figure out the acid and base by a using a table of strong/weak acids and bases.  The conjugate will have one less or one more H⁺ depending on if it's an acid or a base.

The expression for Kₐ of the reaction is below.  You have to put the acid and its conjugate base on the top and the base and its conjugate on the bottom.  I didn't put in H₂O since, although it is the base in this equation, it isn't really a base.

K_{a}=\frac{[HI][H_{3}O] }{[I_{2}] }

Solid zinc reacts with solid manganese (IV) oxide producing solid zinc oxide and solid manganese (III) oxide.

Zn  +  2 MnO₂  ⇒  ZnO  +  Mn₂O₃

This is a redox reaction.  The Zn is being oxidized, and the Mn is being reduced.

Oxidation:    Zn  ⇒  Zn⁺²  +  2 e⁻

Reduction:   Mn⁺⁴  +  e⁻  ⇒  Mn⁺³

Aqueous silver nitrate reacts with aqueous calcium chloride.

2 AgNO₃  +  CaCl₂  ⇒  2 AgCl  +  Ca(NO₃)₂

This is a precipitation reaction.  You have two soluble salts combing to form a solution.  You now need to figure out which of the compounds produced are not soluble.  AgCl is the compound that is not soluble in water, making it the precipitate.

I think I covered everything.  If I missed something let me know.
