Current global climate change is the seventh climate change event in the past 650,000 years. is one
Answer:
33 %
Explanation:
Step 1: Given data
Initial moles of the acid (nHA(0)): 6 mol
Moles of the conjugate base at equilibrium (nA⁻(eq))
Step 2: Write the balanced generic acid dissociation reaction
HA(aq) ⇄ A⁻(aq) + H⁺(aq)
Step 3: Calculate the percent ionization
We will use the following expression.
![\alpha = \frac{nA^{-}(eq)}{nHA(0)} \times 100 \% = \frac{2mol}{6mol} \times 100 \% = 33 \%](https://tex.z-dn.net/?f=%5Calpha%20%3D%20%5Cfrac%7BnA%5E%7B-%7D%28eq%29%7D%7BnHA%280%29%7D%20%5Ctimes%20100%20%5C%25%20%3D%20%5Cfrac%7B2mol%7D%7B6mol%7D%20%5Ctimes%20100%20%5C%25%20%3D%2033%20%5C%25)

Explanation :
- Alpha decay : When a larger nuclei decays into smaller nuclei by releasing alpha particle. In this process, the mass number and atomic number is reduced by 4 and 2 units respectively.
General representation of alpha decay :
![_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}Y+_2^4\alpha](https://tex.z-dn.net/?f=_Z%5EA%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ-2%7D%5E%7BA-4%7DY%2B_2%5E4%5Calpha)
- Beta decay : In this process, a neutron is converted into a proton and an electron. In this decay, the atomic number is increased by 1 unit.
General representation of beta decay :
![_Z^A\textrm{X}\rightarrow _{Z+1}^{A}Y+_{-1}^0e](https://tex.z-dn.net/?f=_Z%5EA%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ%2B1%7D%5E%7BA%7DY%2B_%7B-1%7D%5E0e)
- Gamma decay : In this process, the unstable nuclei transformed into stable nuclei by releasing gamma rays. In this process, the mass number remains same.
General representation of gamma decay :
![_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma](https://tex.z-dn.net/?f=_Z%5EA%5Ctextrm%7BX%7D%5E%2A%5Crightarrow%20_Z%5EA%5Ctextrm%7BX%7D%2B_0%5E0%5Cgamma)
Answer:
D.
Explanation:
You try to get 8 electron on the outermost "shell" so you have no left over or "valence" electrons.
Answer:
The many folds result in more surface area for ribosomes to attach and thus allowing protein synthesis to occur at a more efficient rate.
