Answer : The formula of carbonic acid is,
Explanation :
Acid : It is a substance that has ability of donating proton or hydrogen ion, . That means, in acid hydrogen should be present in the compound.
The element carbonate is the non-metal polyatomic ion. The stable oxidation state of phosphate ion is, (-2).
When the hydrogen combine with the carbonate ion, it forms hydrogen carbonate (carbonic acid). The formula of carbonic acid is, .
It is an ionic compound in which the a metal (hydrogen) react with the non-metal (carbonate ion) and combine with the an ionic bond by the criss-cross method.
Hence, the formula of carbonic acid is,
Answer:
= -457.9 kJ and reaction is product favored.
Explanation:
The given reaction is associated with 2 moles of
Standard free energy change of the reaction () is given as:
, where T represents temperature in kelvin scale
So,
So, for the reaction of 1.57 moles of ,
As, is negative therefore reaction is product favored under standard condition.
Answer:
a)
b)
Explanation:
Equation of reaction:
Initial pressure 3 1 0
Pressure change 2P 1P 2P
Total pressure = (3-2P) + (1-P) + (2P)
Total Pressure = 3.75 atm
(3-2P) + (1-P) + (2P) = 3.75
4 - P = 3.75
P = 4 - 3.75
P = 0.25 atm
Let us calculate the pressure of each of the components of the reaction:
Pressure of XO2 = 3 - 2P = 3 - 2(0.25)
Pressure of XO2 =2.5 atm
Pressure of O2 = 1 - P = 1 -0.25
Pressure of O2 = 0.75 atm
Pressure of XO3 = 2P = 2 * 0.25
Pressure of XO3 = 0.5 atm
From the reaction, equilibrium constant can be calculated using the formula:
Standard free energy:
b) value of k−1 at 27 °C, i.e. 300K
