**answer asap with explanation the table shows the nature of the reactants and products formed in a certain type of chemical reaction. nature of reactants and products reactants ionic compound + ionic compound products ionic compound + ionic compound which of the following is true about this type of chemical reaction? it is a single replacement reaction, and all four compounds are different. it is a double replacement reaction, and all four compounds are different. it is a single replacement reaction, and each compound has the same set of ions. it is a double replacement reaction, and each compound has the same set of ions.

It is a double replacement reaction, and all four compounds are different.

Step-by-step explanation:

The equation for the reaction is

This must be a double replacement reaction, in which the metal cations trade partners and all four compounds are different.

(A) and (C) are wrong, because single replacements involve elements in reactions of the type

element + compound ⟶ element + compound

(D) is wrong because, if each compound retained the same set of ions, there would be no reaction.  

yes definetly because you are using energy

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.
