The phase change in which the water molecules become most orderly is the freezing. This is the process of changing water as liquid to its solidified form. The process of freezing is an exothermic which means that for this to occur, heat should be removed from the system.
Decomposition reaction - because there is one reactant and two products
Answer:
Answer: Kp = 4.5
Explanation:
The balanced equation for the production of synthetic gas is
CH4 + H20 ⇒ CO + 3H2
Let x be the change in the concentration of each species at equilibrium
CH4 + H20 ⇔ CO + 3H2
Initial 0.60 2.6 0 0
Change -x -x +x +3x
Equilibrium 0.60-x 2.6-x x 3x
Given that the equilibrium partial pressure of H2= 1.4 atm
then, 3x= 1.40
x= 1.4/3 = 0.466667
The equilibrium concentrations are
{CH4} = 0.60- x = 0.60 - 0.466667 = 0.133333atm
{H2O} = 2.60- x = 2.60 - 0.466667 = 2.133333atm
{CO} = x = 0.466667atm
{H2} = 1.4atm (given)
Kp = <u>{CO}{H2}³</u>
{CH4}{H2O}
Kp = <u>(0.466667)(1.4)³</u>
(0.133333)(2.133333)
= 4.501875
Kp = 4.5
Given :
An atom Iodine.
To Find :
How many electrons will an iodine atom donate or accept, based on its number of valence electrons :
A.donate seven electrons
B.accept one electron
C.donate one electron
D.accept seven electrons
Solution :
We know, valence electron in Iodine is 7 electrons.
So, it is easy for iodine to accept 1 electron rather than giving all 7 electrons to another element.
Therefore, Iodine will accept one electron ( Option B.).
Hence, this is the required solution.
