List what type the following reactions are:
1) naoh (mal. * kno3 (aq) - nano3 (me) + koh (aq)
2) che (0) + 2 o2 () - co2(g) + 2 h2o (9)
3) 2 fe(n) + 6 nabr (aq) → 2 febrs (aq) + 6 na )
4) caso4 (aa) + mg(oh)2 (aq) --> ca(oh)2 (aq) + mgso4 (aq)
5) al(s) + cu* (ac) --> al(aq) + 3 cu (s)
6) pb (s) + o2(g) -> pbo2 (aq)
7) na2co3(aq) -> na20 (aq) + co2 (9)

the solar system used to have much dust particles option no d

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 answer is minerals.
