Add electron dots and charges as necessary to show the reaction of potassium and bromine to form an ionic compound
S_A_V [24]

Explanation: Electron dot structures are the lewis dot structures which represent the number of valence electrons around an atom in a molecule.

The electronic configuration of potassium is [Ar]4s^1

Valence electrons of potassium are 1.

The electronic configuration of Bromine is [Ar]4s^24p^5

Valence electrons of bromine are 7.

These two elements form ionic compound.

Ionic compound is defined as the compound which is formed from the complete transfer of electrons from one element to another element.

Here, one electron is released by potassium which is accepted by bromine element. In this process, Potassium becomes cation having +1 charge and Bromine become anion having (-1) charge.

The ionic equation follows:

K^++Br^-\rightarrow KBr

The electron dot structure is provided in the image below.

Newton's first law of motion is the law of inertia. There are basically "two parts" to the law of inertia. The first part says that an object at rest tends to remain at rest unless it is acted on by an outside force. Think of gravity.

How many moles of gas are present in 57.20 L of argon at a pressure of 1 atm and a temperature of 0°C?
slamgirl [31]

Answer:

n= 2.55 moles

Explanation:

Using the formula of ideal gas law:

PV = nRT

  nRT=PV

n= PV/RT

  n= number of moles

  R= Avogadro constant = 0.0821

  T= Temperature in K => ºC + 273.15 K

  V= volume in L

  P= pressure in atm

n= (1 atm)(57.20 L) / (0.0821)(237.15 K)

n= 2.50 moles
