Answer:
Concentration of sodium carbonate in the solution before the addition of HCl is 0.004881 mol/L.
Explanation:
Molarity of HCl solution = 0.1174 M
Volume of HCl solution = 83.15 mL = 0.08315 L
Moles of HCl = n
According to reaction , 2 moles of HCl reacts with 1 mole of sodium carbonate.
Then 0.009762 mol of HCl will recat with:
Moles of Sodium carbonate = 0.004881 mol
Volume of the sodium carbonate containing solution taken = 1L
Concentration of sodium carbonate in the solution before the addition of HCl:
![[Na_2CO_3]=\frac{0.004881 mol}{1 L}=0.004881 mol/L](https://tex.z-dn.net/?f=%5BNa_2CO_3%5D%3D%5Cfrac%7B0.004881%20mol%7D%7B1%20L%7D%3D0.004881%20mol%2FL)
Answer:
Explanation:
How do I describe an ion?
<h2>an ion is an atom that has had electrons added or taken away from it.</h2><h2>they do this in order to obtain a stable electronic configuration like their closest noble gas..see Periodic Table column 18 which is also column VIIIA</h2><h2>If they gain electrons, they are negative and are called</h2><h2>ANIONS</h2><h2>if they lose electrons they are positive and are called</h2><h2>CATIONS </h2><h2 />
Answer:
No. it,s not possible.
Explanation:
Because you know that ionic compound is having large inter-molecular forces. -77C* is for a compound having v.very small inter-molecular forces.you must know that M.B is directly varing with inter-molecular forces.
