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

Answer : The correct option is, (A)

Explanation :

Binary ionic compound : It is a type of 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 chlorine.

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

Hence, the is a binary ionic compound.

to make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 ml of water at 80 degrees celsius. when the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
