The ratio of H⁺ ions to OH⁻ ions at a pH = 2 is 10¹⁰
<h3>Further explanation</h3>
Given
ph = 2
Required
The concentration of H⁺ and OH⁻ ions
Solution
- The concentration of H⁺ ions
pH=-log[H⁺]
2=-log[H⁺]
[H⁺]=10⁻²
- The concentration of OH⁻ ions
pH+pOH=14
pOH=14-2
pOH=12
pOH=-log[OH⁻]
12=-log[OH⁻]
[OH⁻]=10⁻¹²
- The ratio of H⁺ ions to OH⁻ ions at a pH = 2
Answer:
The molecules of solid CO2 are much closer together than the molecules of CO2 gas.
A tend line I believe (I am going off the other guy cause they are right.)
The answer is iii) decreasing the pressure of the system. When the pressure is decreased, the equilibrium will shift to the right because it has 12 moles of gas which is greater than the number of moles of gas on the left side, which is 6 moles. Equilibrium shifting to the side that exerts greater pressure is favored to offset the decrease in pressure.
WOW, I gave you the answer, i used a periodic table, i got the mass of gold and i linked a helpful link my teacher gave me because we used it in a lab once.
