Which is a binary ionic compound? a. mgcl2 b. c6h12o6 c. co2 d. po43- e. ch4

Option A)

Magnesium chloride, MgCl2, is a binary compound with bonds with relatively high ionic character.

Answer : The correct option is, (A)

Explanation :

Binary ionic compound : It is defined as the compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal.

From the given options, option (A) is a binary ionic compound because in this compound Mg is a metal which combine with the a non-metal element that is chlorine.

While the other options are the covalent compounds that are formed by the combination of non-metal and non-metal elements.

Hence, the is a binary ionic compound.

  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-

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
