If a neuronal membrane, which is normally slightly passively permeable to K+, becomes impermeable, but the Na+/K+-ATPase remains active, the neuron's resting potential would become: more negative, because [K+] increases inside the neuron more negative, because [K+] increases outside the neuron more positive, because [K+] increases inside the neuron more positive, because [K+] increases outside the neuron

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

the awnser is group 12
