Answer: The electrons get transferred from potassium to chlorine to form potassium chloride

Explanation:

Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.

The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.

Potassium is the 19th element of the periodic table having electronic configuration of $1s^22s^22p^63s^23p^64s^1$

This element will loose 1 electron to form $K^+$ ion

Chlorine is the 17th element of the periodic table having electronic configuration of $1s^22s^22p^63s^23p^5$

This element will gain 1 electron to form $Cl^-$ ion

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

The ionic compound formed will have a chemical formula of KCl

Hence, the electrons get transferred from potassium to chlorine to form potassium chloride

A sample of oxygen gas has a volume of 150.0 ml when its pressure is 0.947 atm. what will the volume of the gas be at a pressure

earnstyle [38]

Boyle's law gives the relationship between pressure and volume of gas. It states that for a fixed amount of gas at constant temperature, pressure is inversely proportional to volume of gas.
PV = k
where P - pressure, V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation.
substituting the values in the equation
0.947 atm x 150.0 mL = 0.987 atm x V
V = 144 mL
therefore new volume is 144 mL

What type of ion do elements from each of the following groups form , group1 group 7.

Artemon [7]

Answer:

group 1 - cations charge +1

group 7 - anions charge -1

Explanation:

Group 1 has one valence electron and will lose one electron to complete the octet.

Group 7 has 7 valence electrons and will accept an electron to complete the octet.

What is the molar mass of a gas with a density of 3.50 g/L at a

Kruka [31]

Answer:

104 g/mol

Explanation:

Use the ideal gas equation:

$pV=nRT$

Where:

p is pressure: 0.950atm
V is volume: unknown
n is number of moles: unknown
R is the universal constat of gases: 0.08206 atm.liter/ (K.mol)
T is the absolute temperature: 345K

Use the molar mass of the gas to include the density in the formula:

molar mass = mass in grams / number of moles

⇒ mass in grams = number of moles × molar mass

density = mass in grams / volume

⇒ density = number of moles × molar mass / volume

density = (n/V) × molar mass

⇒ n/V = density / molar mass

Clear n/V from the gas ideal equation and subsittute with density/molar mass:

n/V = p/(RT)

density / molar mass = n/V

density/molar mass = p/(RT)

molar mass = density × RT / p

Now you can subsitute the data:

molar mass = (3.50g/liter) × 0.08206 atm.liter/(K.mol) × 345K / 0.950 atm

molar mass = 104.3 g/mol

Round to the nearest whole number: 104g/mol ← answer
