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:
C18H38(s) + O2(g) → CO₂(g) + H₂O(g).
Explanation:
C₁₈H₃₈ is called Octadecane and it is an Alkane as the molecular formula follows the general formula of Alkanes which is CnH2n+2 .
C₁₈H₃₈ reacts with Oxygen and forms Carbon Dioxide (CO₂) and Water (H₂O).
We can say that on oxidation Octadecane gives Carbon Dioxide (CO₂) and Water (H₂O) because on passing Oxygen over Octadecane the above products are formed.
C18H38(s) + O2(g) → CO₂(g) + H₂O(g).
Answer:
Color, odor, density, melting temperature, boiling temperature, and solubility are examples of physical properties. Physical properties can be used to identify a pure substance.

The answer is Oxygen. The<span> elements that has the same lewis structure as sulfur is Oxygen. </span><span>This is due to the fact that although the two compounds have different electronic configurations, the two have the same arrangement of electrons in their outermost orbits. </span>
