Predict which compound would have the highest melting point and explain why.

A) CO - It is polar and has dipole-dipole forces.
B) CO2 - It has really strong dispersion forces.
C) SiO2 - It consists of a covalent network.
D) P2O5 - It has strong dipole-dipole forces.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

catya your not at all which answer i've seen you do this on another question!
