Write the formula for each of the following. (a) sodium carbonate (b) sodium bicarbonate (c) carbonic acid (d) hydrofluoric acid (e) sulfur trioxide (f) copper(II) sulfate (g) sulfuric acid (h) hydrosulfuric acid

(A) Na2CO3

(B) NaHCO3

(C) H2CO3

(D) HF

(E) SO3

(F) CuSO4

(G) H2SO4

(H) H2S

- Remember to place the subscripts correctly. Hope I helped.

Have a good day and stay safe!

Explanation:

(a) sodium carbonate - Na2CO3

(b) sodium bicarbonate - NaHCO₃

(c) carbonic acid - H2CO3

(d) hydrofluoric acid - HF

(e) sulfur trioxide - SO3

(f) copper(II) sulfate - CuSO4

(g) sulfuric acid - H2SO4

(h) hydrosulfuric acid -  H2S

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

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.
