The proper word equation for
4Fe + 3Sn(NO3)4 = 4Fe(NO3)3 + 3Sn is as below
Iron + Tin (iv) nitrate = iron(iii) nitrate + Tin
iron displaces tin from it compound ( Tin (iv) nitrate to form iron (iii) nitrate and tin.
from the equation above 4 moles of Fe displaces 3 moles of Sn(NO3)4 to form 4 moles of Fe(NO3)3 and 3 moles of SN
Answer:
Atoms models are bigger but they don not match the true or positive way of atoms. to make them visible scientists make their models that resembled with the real ones.
Explanation:
Molecules are microscopic entities and only can be seen under a microscope.
That is correct boi boi boi boo boi
Answer:
11
Explanation:
Moles of KOH = 
Volume of water = 10 liters
Concentration of KOH is given by
![[KOH]=\dfrac{10^{-2}}{10}\\\Rightarrow [KOH]=10^{-3}\ \text{M}](https://tex.z-dn.net/?f=%5BKOH%5D%3D%5Cdfrac%7B10%5E%7B-2%7D%7D%7B10%7D%5C%5C%5CRightarrow%20%5BKOH%5D%3D10%5E%7B-3%7D%5C%20%5Ctext%7BM%7D)
![[KOH]](https://tex.z-dn.net/?f=%5BKOH%5D)
is strong base so we have the following relation
![[KOH]=[OH^{-}]=10^{-3}\ \text{M}](https://tex.z-dn.net/?f=%5BKOH%5D%3D%5BOH%5E%7B-%7D%5D%3D10%5E%7B-3%7D%5C%20%5Ctext%7BM%7D)
![pOH=-\log [OH^{-}]=-\log10^{-3}](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E%7B-%7D%5D%3D-%5Clog10%5E%7B-3%7D)
So, pH of the solution is 11
