The reaction between lead ion and chloride ion is given below: Pb2+(aq) + 2 Cl-(aq) PbCl2(s)
We therefore know that which of the following reactions can also occur?
a) Pb(s) + Cl2(g) PbCl2(s)
b) PbCl2(s) Pb(s) + Cl2(g)
c) CH4(g) CO(g) + 3 H2(g)
d) None of the Above

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
