2. Match the chemical reaction with its name a. oxidation-reduction
b. hydration
c. dissolution
d. hydrolysis
1. CaSO4•2H2O + 2H2O = Ca^2+ + SO4^2- + 4H2O
2. FeOOH + e^- + 3H+ =Fe^2+ + 2H2O
3. KAISi3O8 + H2O = HAISi3O8 + K^+ +OH^-
4. 5Fe2O3 + 9H2O Fe10O15•9H2O

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.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
