An unknown group 1 metal carbonate m2co3 (m=li, na or k) was reacted with excess 2 m hcl and the mass of co2 released was determined by mass difference. the initial mass of solid m2co3 was 2.002 g and the mass of co2 released was 1.206 g.

a. write the balanced chemical equation for the reaction of m2co3 with hcl.

b. what is the mole ratio of co2 to m2co3

c. calculate the molar mass of the unknown metal carbonate and identify the group 1 metal.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

im pretty sure its b
