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

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
