Equation is as follow,
<span> 4 Na (s) + O</span>₂ <span>(g) → 2Na</span>₂<span>O (s)
According to equation,
91.92 g (4 moles) of Na produces = 123.92 g (2 moles) of Na</span>₂O
So,
17.4 g of Na will produce = X g of Na₂O
Solving for X,
X = (17.4 g × 123.92 g) ÷ 91.92 g
X = 23.45 g of Na₂O
Answer : The chemical symbol for the element that results from this process is, (Ar) for argon.
Explanation :
Electron capture : In this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. Simply, a proton and an electron combines together to form a neutron. Mass number does not change in this process.
![_Z^A\textrm{X}+_{-1}^0\textrm{e}\rightarrow _{Z-1}^A\textrm{Y}](https://tex.z-dn.net/?f=_Z%5EA%5Ctextrm%7BX%7D%2B_%7B-1%7D%5E0%5Ctextrm%7Be%7D%5Crightarrow%20_%7BZ-1%7D%5EA%5Ctextrm%7BY%7D)
The equation for the given reaction is,
![_{19}^{40}\textrm{K}+_{-1}^0\textrm{e}\rightarrow _{18}^{40}\textrm{Ar}](https://tex.z-dn.net/?f=_%7B19%7D%5E%7B40%7D%5Ctextrm%7BK%7D%2B_%7B-1%7D%5E0%5Ctextrm%7Be%7D%5Crightarrow%20_%7B18%7D%5E%7B40%7D%5Ctextrm%7BAr%7D)
Thus, the chemical symbol for the element that results from this process is, argon (Ar).
Answer:
Chemical Reactions. ... Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules.
