Answer:

The balanced chemical reaction is given as:

Fe(NO_3)_3(aq)+3LiOH(aq)\rightarrow Fe(OH)_3(s)+3LiNO_3(aq)

Explanation:

When aqueous ferric nitrate is allowed to react with aqueous lithium hydroxide it gives solid precipitate of ferric hydroxide and aqueous solution of lithium nitrate. The balanced chemical reaction is given as:

Fe(NO_3)_3(aq)+3LiOH(aq)\rightarrow Fe(OH)_3(s)+3LiNO_3(aq)

According to reaction , 1 mole of ferric nitrate reacts 3 moles of lithium hydroxide to give 1 mole of ferric hydroxide and 3 moles of lithium nitrate.

⦁ Find the concentration of H+, OH-, PH and POH of 0.03 M of magnesium hydroxide which ionizes to the extent of only 1 /3 in aqu
lions [1.4K]

Answer:

pH=12.3\\\\pOH=1.7\\

[H^+]=5x10^{-13}M

[OH^-]=0.02M

Explanation:

Hello there!

In this case, according to the given ionization of magnesium hydroxide, it is possible for us to set up the following reaction:

Mg(OH)_2(s)\rightleftharpoons Mg^{2+}(aq)+2OH^-(aq)

Thus, since the ionization occurs at an extent of 1/3, we can set  up the following relationship:

\frac{1}{3} =\frac{x}{[Mg(OH)_2]}

Thus, x for this problem is:

x=\frac{[Mg(OH)_2]}{3}=\frac{0.03M}{3}\\\\x=  0.01M

Now, according to an ICE table, we have that:

[OH^-]=2x=2*0.01M=0.02M

Therefore, we can calculate the H^+, pH and pOH now:

[H^+]=\frac{1x10^{-14}}{0.02}=5x10^{-13}M

pH=-log(5x10^{-13})=12.3\\\\pOH=14-pH=14-12.3=1.7

Best regards!

What is the difference between conduction and induction?​
Gnesinka [82]
Charging by conduction involves the contact of a charged object to a neutral object. ... In contrast to induction, where the charged object is brought near but never contacted to the object being charged, conduction charging involves making the physical connection of the charged object to the neutral object.

Sand is converted to pure silicon in a three step process. the third step is sicl4(g) + 2mg(s) → 2mgcl2(s) + si(s) δh = –625.6 k
JulijaS [17]
The reaction is that,
1 mole is SiCL4 will produce 1 mole of Si(s) Since there is 1 to 1 relationship then we just multiply the enthalpy of reaction by the number of moles
Enthalpy = -625.5 kJ/mole × 12.5 Moles 
= -7,818.75 KJ
= -0.78 ×10⁴KJ
