The balanced dissociation equation for Cs₂CO₃ is:
Cs₂CO₃(aq) —> Cs⁺(aq) + CO₃²¯(aq)
A dissociation equation is an equation showing the available ions present in a solution.
To obtain the dissociation equation, the compound must be dissolved in water to produce an aqueous solution.
The dissociation equation for Cs₂CO₃ can be written as follow
Cs₂CO₃(aq) —> Cs⁺(aq) + CO₃²¯(aq)

Answer:
Alpha particle
Explanation:
An alpha particle is a helium nucleus, 2 protons and 2 neutrons, loss of an alpha particle give a new element with an atomic number 2 less than the original isotope and an atomic mass that is lower by about 4 amu.
<span>8.21 L of C3H8(g)
Lets take c as the molar volume at that temperature.
c L <><> 5c L
C3H8 (g) + 5O2 (g) --> 3CO2 + 4H2O + Q
8.21 L <><> x L
x = (8.21 * 5c)/c = 8.21 * 5 = 41.05 L O2 consumed for a 100% yield.</span>
Answer:
40:1 is the ratio of the magenta phenolphthalein concentration to the colorless phenolphthalein concentration.
Explanation:
To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:
![pH=pK_a+\log(\frac{[salt]}{[acid]})](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%28%5Cfrac%7B%5Bsalt%5D%7D%7B%5Bacid%5D%7D%29)
![pH=pK_a+\log(\frac{[magenta(Php)]}{[Php]})](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%28%5Cfrac%7B%5Bmagenta%28Php%29%5D%7D%7B%5BPhp%5D%7D%29)
We are given:
= negative logarithm of acid dissociation constant of phenolphthalein = 9.40
![[magenta(Php)]](https://tex.z-dn.net/?f=%5Bmagenta%28Php%29%5D)
= concentration of magenta phenolphthalein
![[Php]](https://tex.z-dn.net/?f=%5BPhp%5D)
= concentration of colorless phenolphthalein
pH = 11
Putting values in above equation, we get:
![11=9.40+\log(\frac{[magenta(Php)]}{[Php]})](https://tex.z-dn.net/?f=11%3D9.40%2B%5Clog%28%5Cfrac%7B%5Bmagenta%28Php%29%5D%7D%7B%5BPhp%5D%7D%29)
![\log(\frac{[magenta(Php)]}{[Php]})=11-9.40=1.6](https://tex.z-dn.net/?f=%5Clog%28%5Cfrac%7B%5Bmagenta%28Php%29%5D%7D%7B%5BPhp%5D%7D%29%3D11-9.40%3D1.6)
![\frac{[magenta(Php)]}{[Php]}=10^{1.6}=39.81 :1 \approx 40:1](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bmagenta%28Php%29%5D%7D%7B%5BPhp%5D%7D%3D10%5E%7B1.6%7D%3D39.81%20%3A1%20%5Capprox%2040%3A1)
40:1 is the ratio of the magenta phenolphthalein concentration to the colorless phenolphthalein concentration.
