The answer is Helium. hope its helpful (:
Answer: 1.65
Explanation:
For a 0.0224M HCl solution the concentration of the hydrogen ions,
[H+] = is 0.0224 mol/L (i.e. 0.0224 M)
pH = −log[H+]
Substituting H+ = 0.0224 into the equation
pH = - log[0.0224]
pH = 1.649
pH = 1.65
Number of O atoms : 24
<h3>Further explanation</h3>
Given
C₆H₁₂O₆ compound
Required
Number of atoms
Solution
A molecular formula shows the number of atomic elements in compound.
The empirical formula is the smallest comparison of the atoms
Glucose-C₆H₁₂O₆ is composed of 3 elements, namely C, H, and O.
The number of atoms in a compound can usually be seen from the subscript number after the atom and the reaction coefficient shows the number of molecules
So number of O atoms :
= 4 x 6 = 24 atoms
Hey there!
The correct answer is C
Hope this helps you!
Always remember, you are a Work Of Art!
