For the reaction 2na + cl2 → 2nacl, how many grams of chlorine gas are required to react completely with 57.5 mol of sodium?

1019.27 g.

Explanation:

2Na + Cl₂ → 2NaCl,

It is clear 2 moles of Na with 1 mole of Cl₂ to produce 2 moles NaCl.

2 moles of Na need → 1 mol of Cl₂, from the stichiometry.

57.5 moles of Na need → ??? mol of Cl₂.

∴ The no. of moles of Cl₂ is needed to react with 57.5 mol Na = (1 mol)(57.5 mol)/((2 mol) = 28.75 mol.

∴ the mass of Cl₂ is needed to react with 57.5 mol Na = (no. of moles of Cl₂)(molar mass of Cl₂) = (28.75 mol)(35.453 g/mol) = 1019.27 g.

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.
