The chemical breakdown of enormous quantities of organic material buried in the sedimentary rocks has produced ethane gas.
Answer:
The "unit" remaining after conversion is atoms.
This is a way to calculate the number of atoms, in an specific mass.
Explanation:
When you have a mass, multiplying the molar mass, "grams" are cancelled, so you finally obtained, number of moles.
Moles . atoms/mol, cancel the word mol so you will find out a number of atoms, present at the mass from, the begining.
For example, how many atoms are in 10 g of NaCl
Molar mass NaCl = Na mass + Cl mass
23 + 35.45 = 58.45 g/m
10 g . 1 / 58.45 mol/g . NA/ 1 mol = 3.42x10²⁰ atoms
NA = Avogadro number
The balanced equation is

Answer:
a) [H3O+] = 1.00 E-10 M ⇒ [OH-] = 1.0 E-4 M
b) [H3O+] = 1.00 E-4 M ⇒ [OH-] = 1.0 E-10 M
c) [H3O+] = 9.90 E-6 M ⇒ [OH-] = 1.0 E-9 M
Explanation:
- 14 = pH + pOH
- pH = - Log [H3O+]
a) [H3O+] = 1.00 E-10 M
⇒ pH = - Log(1.00 E-10) = 10
⇒ pOH = 14 - 10 = 4
⇒ 4 = - Log[OH-]
⇒ [OH-] = 1.0 E-4 M
b) [H3O+] = 1.00 E-4 M
⇒ pH = 4
⇒ pOH = 10
⇒ [OH-] = 1.0 E-10 M
c) [H3O+] = 9.90 E-6 M
⇒ pH = 5
⇒ pOH = 9
⇒ [OH-] = 1.0 E-9 M
I'd say it's partially dissociating into products
