Answer:
Hydrogen ions, Hydroxyl ions
Answer:
a) Molar fraction:
Methane: 67,5%
Ethane: 25,1%
Propane: 7,4%
b) Molecular weight of the mixture: 25,16 g/mol
Explanation:
with a basis of 100 kg:
Moles of methane:
500 g × = 31,2 moles
Mass of ethane
350 g × = 11,6 moles
Mass of propane
150 g × = 3,4 moles
Total moles: 31,2 moles + 11,6 moles + 3,4 moles = <em>46,2 moles</em>
Molar fraction of n-methane:
=67,5%
Molar fraction of ethane:
= 25,1%
Molar fraction of propane:
= 7,4%
b) Average molecular weight:
= <em>25,16g/mol</em>
I hope it helps!
Answer:
equal to [OH-]
Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−)
Answer:
When two or more atoms chemically bond together, they form a molecule. When molecules are made from two or more different kinds of atoms, the substances are called compounds. If molecules are made from only one kind of atom, the substances are elements.
