Alkaline : Be , Mg , Ca , Sr ,Ba ,Ra

Transition : Sc ,Ti ,V ,Cr ,Mn , Fe , Co, Ni Cu , Zn ,Y ,Zr ,Nb ,Mo ,Tc ,Ru , Rh , Pd , Ag , Cd , In , Sn, La ,Hf ,Ta ,W ,Re ,Os ,Ir ,Pt ,Au ,Hg

Non -Metals: Most of the p-block element are non metal. They are present in upper - right corner of the periodic table.

Non - metals : H , He , C ,N , O , F ,P ,S , Cl, Ar , Br , Xe ,At ,Rn,  

Metalloid : They show properties of both the metals and the non - metals.

Also called as semimetals

Metalloid : B ,Si ,Ge ,As ,Sb ,Te ,Po

<u>In table F </u>:

B = metalloid  , N = non metal ( wrong-match) , Ra  = metal ( wrong-match) , He = Non - metal ( wrong-match)

<u>In table G : Correctly matched </u>

I =  Non - metal , Ca = metal , Rb = metal , As = metalloid

<u>In table H</u>:

Ni = metal ( wrong-match) , C = metalloid ( wrong-match) , Mg = metal , Pb = Metal

<u>In table J</u>:

Cu = metal , Sb = Metalloid( wrong-match)  , S = non metal( wrong-match) ,Ne = non metal

a sample of ammonia liberates 5.66 kj of heat as it solidifies at its melting point . what is the mass of the sample?
Reil [10]
The correct answer for the question that is being presented above is this one: "<span>16.728 g."</span>

Given that 
ΔHsolid = -5.66 kJ/mol.
This means that 5.66 kJ of heat is released when 1 mole of NH3 solidifies 

When 5.57 kJ of heat is released
amount of NH3 solidifies = 5.57/5.66 = 0.984 moles 

<span>molar mass of NH3 = 17 g/mole </span>
<span>1 mole of NH3 = 17 g </span>
So, 0.984 moles of NH3 = 17 X 0.984 = 16.728 g
