if my answers helped you please tell me, therefore I know.. that I did them correctly or incorrectly. anyways, have a great day/night!
Answer:
2HgO → 2Hg + O₂
The reaction is a decomposition reaction because from one reactant two products were obtained
Explanation:
The problem here involves balancing the chemical reaction given and also classifying the reaction.
The unbalanced expression is given as:
HgO → Hg + O₂
Assign the alphabets a,b and c as coefficients that will balance the equation
aHgO → bHg + cO₂
Conserving Hg: a = b
O: a = 2c
So, let c = 1, a = 2 b = 2
Therefore;
2HgO → 2Hg + O₂
The reaction is a decomposition reaction because from one reactant two products were obtained
The M stands for molar, so it would be 5.0 molar. is that what you need?
