word equation

Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 +  2Al(OH)3

Explanation:

1 mole of aluminium sulfate on reaction with 3 moles of calcium hydroxide gives 3 moles of calcium sulfate and 2 moles of aluminium hydroxide.

Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 +  2Al(OH)3

here we have 2 moles of aluminium hydroxide so that aluminium on both the side can balance.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
