Hope this helps chief.
Answer: 1 = 1e-5
Explanation: Divide the pressure value by 100000
If you go backwards two elements, you will find Neon (Ne). If you go forwards six, you will find Argon (Ar). so the closest will be neon
Answer:
Hey, I'll help but I don't know what your options are.
Explanation:
The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
<h3>Determine hydronium ion concentration when pH = 7 </h3>
Given that :
pH = 8.0
Hydronium ion concentration = 1 * 10⁻⁸ mole/liter
Resolving the question
8.0 = 1 * 10⁻⁸ mole/liter
7.0 = x
therefore :
x = 7 ( 1 * 10⁻⁸ ) / 8.0
= 8.75 * 10⁻⁹ mole/liter
Hence we can conclude that The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
