Answer: KCl

Explanation: Potassium [K]  has an atomic no of 19 and the electronic configuration is:

K :1s^22s^22p^63s^23p^64s^1 tends to get stable by losing one electron and forming K^+

Chlorine [Cl] has atomic no of 17 and thus the electronic configuration is :

Cl :1s^22s^22p^63s^23p^5 tends to get stable by gaining one electron and forming Cl^-

K^+ and Cl^- attract each other and form an ionic bond. As we have a chlorine molecule that is two atoms of chlorine are present, 2 atoms of potassium will react to form 2 moles of KCl.

2K+Cl_2\rightarrow 2KCl

Nuclear power plants produce energy using fission. One common fuel, uranium-235, produces energy through the fission reaction 23
Vikentia [17]

Answer:

mass of U-235  = 15.9 g (3 sig. figures)

Explanation:

1 atom can produce -------------------------> 3.20 x 10^-11 J energy

x atoms can produce ----------------------> 1.30 x 10^12 J energy

x = 1.30 x 10^12 / 3.20 x 10^-11

x = 4.06 x 10^22 atoms

1 mol ----------------------> 6.023 x 10^23 atoms

y mol ----------------------> 4.06 x 10^22 atoms

y = 0.0675 moles

mass of U-235 = 0.0675 x 235 = 15.8625

mass of U-235  = 15.9 g (3 sig. figures)

How can indicator be used to determine if a solution is an acid or base
dalvyx [7]

Answer:

To tell if something is an acid or a base, you can use a chemical called an indicator. An indicator changes color when it encounters an acid or base. There are many different types of indicators, some that are liquids and others that are concentrated on little strips of "litmus" paper.

Use LeChâtelier's principle explain why the concentration of NO at equilibrium increases when the reacuon takes place at higher
Tatiana [17]

increasing the temperature shifts the equilibrium in the direction of the reaction in which heat is absorbed.

Explanation:

The concentration of NO at equilibrium will increase when the reaction takes place at a higher temperature because increasing the temperature shifts the equilibrium in the direction of the reaction in which heat is absorbed.

The reaction is an endothermic reaction.

                            N₂  + O₂  + heat  ⇄  2NO

According to Le Chatelier's principle, "if any of the conditions of a system in equilibrium is changed the system will adjust itself in order to annul the effect of the change".

  • In an endothermic reaction, heat is usually absorbed.
  • We see that in the backward reaction, heat is absorbed.
  • If the temperature of this reaction is increased, the backward reaction is favored more.
  • Since the reactants are combining better, more products NO results.
