Balance the equation: ___HgO → ___O2 + ___Hg
2 answers:
Answer:
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical equation for the reaction is:
Thus if the product is , there are 2 atoms of oxygen. When a coefficient 2 is placed in front of the reactant
, there will be 2 atoms of oxygen and 2 atoms of mercury. Thus a coeeficient of 2 is to be added to product side in front of
.

Answer:
The vapor pressure at temperature 363 K is 0.6970 atm
The vapor pressure at 383 K is 1.410 atm
Explanation:
To calculate of the reaction, we use clausius claypron equation, which is:
where,
= vapor pressure at temperature
= vapor pressure at temperature
= Enthalpy of vaporization
R = Gas constant = 8.314 J/mol K
1)
= initial temperature =363 K
= final temperature =373 K
Putting values in above equation, we get:
The vapor pressure at temperature 363 K is 0.6970 atm
2)
= initial temperature =373 K
= final temperature =383 K
Putting values in above equation, we get:
The vapor pressure at 383 K is 1.410 atm
