Answer:
a) The two compounds you will expect in these solution are 1-aminobutane and its conjugate acid.
b) The greatest total amount is of 1-aminobutane.
c) The least total amount is of the conjugate acid.
Explanation:
The equilibrium in water of 1-aminobutane is:
CH₃(CH₂)₃NH₃⁺ ⇄ CH₃(CH₂)₃NH₂ + H⁺
a) The two compounds you will expect in these solution are 1-aminobutane and its conjugate acid.
b) The equlibrium constant is: K = 1,66x10⁻¹¹.
That means you will have 1-aminobutane:Conjugate acid in a ratio of 6x10¹⁰ : 1 .
The greatest total amount is of 1-aminobutane
c) Thus, The least total amount is of the conjugate acid.
I hope it helps!
Answer:
2200 g
Explanation:
Data Given:
no. of moles of Ba₃N₂ = 5 moles
mass of Ba₃N₂ = ?
Solution:
Formula used
no. of moles = mass in grams / molar mass
To find mass rearrange the above equation:
mass in grams = no. of moles x molar mass. . . . . . (1)
molar mass of Ba₃N₂
molar mass of Ba₃N₂ = 3(137.3) + 2(14)
molar mass of Ba₃N₂ = 412 + 28
molar mass of Ba₃N₂ = 440 g/mol
Put values in equation 1
mass in grams = 5 moles x 440 g/mol
mass in grams = 2200 g
So,
mass of Ba₃N₂ = 2200 g
Answer:
All chemical equations goes to the law of conservation of mass which says that matter can not be destroyed nor created which means there has to be an equal amount of atoms of each element on both sides of the equation. I hope that helps, I'm learning this as well.
In an exothermic reaction, heat is released. ΔH for an exothermic reaction is negative. That means that the energy stored in the reactants is higher than the energy stored in the products.
The opposite is true for an endothermic reaction. Heat is absorbed, and <span>ΔH for an endothermic reaction is positive. This means that energy stored in the products is higher than the energy stored in the reactants.</span>
