Classify these reactions according to the type discussed in the chapter.

b) ca2+ + co32- -> caco3
d) 2ccl4 + cro42- -> 2cocl2+ cro2cl2+2cl-
e) ca+ f2-> caf2
f) 2li+h2-> 2lih
g) ba(no3)2+na2so4-> 2nano3+baso4
h) cuo+h2-> cu+h20
i) zn+2hcl-> zncl2+h2
j) 2fecl2+cl2-> 2fecl3

Explanation :

(b)

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or product.

(d)

This reaction is a redox reaction or oxidation-reduction reaction in which sulfur get oxidized and oxygen get reduced.

(e)

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or product.

(f)

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or product.

(g)

This reaction is a double displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.

(h)

This reaction is a single displacement reaction in which the most reactive metal displaces the least reactive metal and forms different product.

(I)

This reaction is a single displacement reaction in which the most reactive metal displaces the least reactive metal and forms different product.

(J)

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or product.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
