#1

  • Ferrous shows variable valency as it's transitive metal.

#For valency=2

\\ \rm\Rrightarrow {Fe(II)\atop Iron}+{S\atop Sulphur}\longrightarrow {FeS\atop Pyrrhotite}

#For valency=3

\\ \rm\Rrightarrow {Fe(III)\atop Iron}+{S\atop Sulphur}\longrightarrow {Fe_2O_3\atop Sesquisulfide}

#2

  • Manganese also shows variable valency

#For valency=2

\\ \rm\Rrightarrow {Mn(II)\atop Manganese}+{O_2\atop Oxygen}\longrightarrow {MnO_2\atop Manganese (II) Oxide}

#For valency=4

\\ \rm\Rrightarrow {Mn(IV)\atop Manganese}+{O_2\atop Oxygen}\longrightarrow {MnO_4\atop Permanganate}

#3

\\ \rm\Rrightarrow {Al\atop Aluminium}+{S\atop Sulphur}\longrightarrow {Al_2S_3\atop Aluminium\:Sulphide}

Describe what does happen to the electrons when metal atoms are bonded together.
tankabanditka [31]

Answer: In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions. Metals are shiny.

Explanation: Hope this helped!

What volume is occupied by 0.109 molmol of helium gas at a pressure of 0.98 atmatm and a temperature of 307 K
KATRIN_1 [288]

Answer:

2.8 L

Explanation:

From the question given above, the following data were obtained:

Number of mole (n) = 0.109 mole

Pressure (P) = 0.98 atm

Temperature (T) = 307 K

Gas constant (R) = 0.0821 atm.L/Kmol

Volume (V) =?

The volume of the helium gas can be obtained by using the ideal gas equation as follow:

PV = nRT

0.98 × V = 0.109 × 0.0821 × 307

0.98 × V = 2.7473123

Divide both side by 0.98

V = 2.7473123 / 0.98

V = 2.8 L

Thus, the volume of the helium gas is 2.8 L.
