There are 0.31 mol in h3po4
<h2>Nucleosynthesis.</h2>
Explanation:
A. the Big Bang occurred; the Big Crunch occurred
Nucleosynthesis is the process by which new atomic nucleus are formed from pre-existing protons and neutrons.
According to cosmic theories, the nucleosythesis began one minute after the occurrence of Big bang and will end with the big Crunch.
The Big bang theory describes all the processes by which the universe came into existence while the big crunch theory explains how universe will come to an end. A
You must know and use the formula for pH.
pH = - log [H3O+], where [H3O+] is the molar concentration of hydronium ion.
So, when pH is 8.0 => 8.0 = - log [H3O+] and you can use antilogarithm (the inverse function of logarithm) to find [H3O+], in this way:
[H3O+] = 10^-8 = 1 * 10 ^-8 M
When, pH = 7.0 =>
7.0 = - log [H3O+] => [H3O+] = 1 * 10^ -7 M
Answer: 1*10^-7 mole / liter
The intermolecular force that attracts two nonpolar molecules is London dispersion forces, which are also called induced dipole-induced
