Answer:
mL * L²
Explanation:
The question in t his problem is to calculate the units of the final answer.
The units in the numerator is mol, ml and L.
The unit in the denominator is mol/L
This leads us to;
Numerator / Denominator = mol * mL * L / (mol / L )
The final units is mL * L²
Answer:
high
Explanation:
because of the strong crystal structure mentioned in the question, ionic compounds require a higher level of heat to melt
Answer: reactants.
Explanation:
To the right of the arrow we have the 'after' situation. This side represents the substances that we have after the reaction has taken place. They are called the products
Answer:
a) ΔGº= -49,9 KJ/mol = - 50 KJ/mol
b) The reaction goes to the right to formation of products
c) ΔG= 84,42 KJ/mol. The direction is to reactive, to the left
Explanation:
a) ΔGº= - RTLnKf
You need to convert Cº to K. 25ºC=298K
Then, ΔGº= - 3,814 J/molK * 298K* Ln(5.6 *10^8)= - 49906 J/mol = -49,9 KJ/mol = - 50 KJ/mol
b) The ΔGº < 0, that means the direct reaction is spontaneous when te reactive and products are in standard state. In other words the reaction goes to the right, to formation of products
c) The general ecuation for chemical reaction is aA + bB → cD + dD. Thus
ΔG=ΔGº + RTLn (([C]^c*[D]^d)/[A]^a*[B]^b)
In this case,
ΔG=ΔGº + RTLn ([Ni(NH3)62+] / [Ni2+]*[NH3]^6 )= 84417 J/mol =84,42 KJ/mol
ΔG >0 means the reaction isn't spontaneous in the direction of the products. Therefore the direction is to reactive, to the left
The hydronium ion concentration of a pH = 9.2 of solution is 6.3 × 10⁻¹⁰M.
<h3>How do we calculate pH?</h3>
pH of the solution is define as the negative logarithm of the concentration of the hydronium ion as:
pH = -log[H⁺]
Or [H⁺] =
Given that pH value = 9.2
On putting values, we get
[H⁺] = = 6.3 × 10⁻¹⁰M
Hence required concentration of hydronium ion is 6.3 × 10⁻¹⁰M.
