A) CH3NH2
This is because CH3NH2 recieved H from CH3COOH
You hydrated yourself, take shower, basically all living organisms need water to function and live
Answer:- cell potential = -0.19 volts
Solution:- The equation that shows the connection between and cell potential, E is written as:
in this equation, n stands for moles of electrons, E stands for cell potential and F stands for faraday constant and it's value is .
It asks to calculate the value of E, so let's rearrange the equation:
Let's plug in the values in it:
since,
Where C stands for coulombs and V stands for volts.
So,
E = -0.19 V
So, the cell potential is -0.19 volts.
Answer:
119.98 mL
Explanation:
Initial volume V1 = 123 ml
Initial temperature = T1 = 21◦C + 273 = 294 K
Initial pressure P1 = 760 Torr - 18.65 Torr = 741.35 Torr
Final volume V2= ???
Final temperature = T2= 21◦C + 273 = 294 K
Final pressure P2 = 760 Torr
From;
P1V1/T1= P2V2/T2
P1V1T2 = P2V2T1
V2 = P1V1T2/P2T1
V2= 741.35 * 123 * 294/760 * 294
V2 = 119.98 mL
The molar solubility of KNO3 is not affected by the PH of the solution.
This is because KNO3 ions are either acidic or basic.KNO3 salt is formed from the reaction of strong acid HNO3 and a strong base KOH and neither the potassium ion nor the nitrate ions can either lose, gain protons or hydrogen ions.
