Answer:
The concentration of Hydrogen Cation is:
Pure water is<u> NEUTRAL</u>
Explanation:
pH = It is negative logarithm of activity of Hydrogen ions.
Activity = concentration for dilute solutions
There are three types of solution based on pH:
1. Acidic solution : Those solution which have pH between 0 to 7 or less than 7 are acidic in nature . They turns blue litmus red.They contain more H+ ions than OH- ions
2. Basic : Those solution which have pH value greater that 7 of between 7 to 14 are basic in nature . They turn red litmus blue.They contain more OH- ions then H+ ions
3 . Neutral : Those solution which have pH = 7 are neutral . They are neither acidic nor basic in nature .They have equa;l concentration of H+ and OH- ions in the solution.
The given water has pH = 7 .This means it is neutral and has low H+ ion concentration in solution. The H+ ion are :
M in water.
OH- =
M in water
So overall neutral
According to the ideal gas law, partial pressure is inversely proportional to volume. It is also directly proportional to moles and temperature. At equilibrium in the following reaction at room temperature, the partial pressures of the gases are found to be PN2 = 0.094 atm, PH2 = 0.039 atm, and PNH3 = 0.003 atm.
<h3>Equilibrium partial pressures</h3>
The initial partial pressures of CO and water are 4.0 bar and 4.0 bar respectively.
The equilibrium partial pressures (in the bar) of CO, H2O, CO2, and H2 are 4−p,4−p, and respectively.
Let p bar be the equilibrium partial pressure of hydrogen.
The expression for the equilibrium constant is
Kp=PCOPH2OPCO2PH2=(4−p)(4−p)p×p=0.1
p=1.264−0.316p
p=0.96 bar.

<em>Balance Chemical Equation:</em>
2H3N(aq) + 3Ca(OH)2(aq) → Ca3N2(aq) + 6H2O(liq)
<em>Explanations:</em>
- According to law of mass of conservation, the chemical equation should be balanced.
- In balance chemical equations, the numbers of same or different atoms in reactants should be equal to the number of different atoms of elements of product side.
Explanation:
1 mole is equal to 1 moles Al2O3, or 101.961276 grams.
