Question

Two molecules of mercury oxide decompose into 2 molecules of mercury and 1 molecule of oxygen gas. Which of the following

equations correctly describes this reaction?
(A) Pro(s)-> Pr(s) + O(g)
(B) Mc₂O(s)-> 2 Mc(s) + O(g)
(C) 2 MnO(s)-> 2 Mn(s) + 20(g)
(D) 2 HgO(s)-> 2 Hg(1) + O₂(8)
Select one:
O a. A
O b. B
OC. C
O d. D

Answer 1

the answer is B bdvausr

Answer 2

D

Step-by-step explanation:

Mercury is Hg. Most of these reaction do not involve Hg. Only D correctly shows a balanced equation with mercury (Hg).

(A) Pro(s)-> Pr(s) + O(g)

(B) Mc₂O(s)-> 2 Mc(s) + O(g)

(C) 2 MnO(s)-> 2 Mn(s) + 20(g)

(D) 2 HgO(s)-> 2 Hg(1) + O₂(8)
