To find the mass of reagent to be added in the reaction, we need to determine the pH of the buffer. Using the following equation
pH= pKa + log ([NH3] / [NH4+])
= 9.26 + LOG ( 0.3 / 0.3)
= 9.26
[h+]= 5.5x10^-10 M, you need to increase that concentration for a ph of 8.6, [H+] needs to be 2.51x10^-9M
2.51x10^-9 moles - 5.5x10^10 moles = 1.96x10^-9 moles
1.96x10^-9 x 36.45g/mole = 7.14x10^-8 g
So the mass of HCI that you should add to the reaction is 7.14x10^-8 g
Answer:
CuSO4(aq)
Explanation:
The aqueous form of copper sulfate will conduct electricity.
The Solid form will not be a good conductor.
C₅H₁₂ will not conduct electricity
CO₂ will not conduct electricity
- Copper sulfate is an ionic compound
- In aqueous solutions or molten forms, ionic compounds can conduct an electric current using free mobile ions as carriers.
- This way, they are electrolytes.
- In solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.
The properties of the atomic orbital are actually
dependent on the quantum numbers.
size of atomic orbital: governed by the principal quantum
number (n)
shape of atomic orbital: governed by the angular momentum
quantum number (l)
orientation in space: governed by the magnetic quantum
number (ml)
Since we are asked about the shape, hence the correct answer
is:
angular momentum quantum number (l)
