You need to look at the electronegativity and decide wheter the difference of both of the numbers are significant enough to form a polar bond
Answer:
In H2CO3(aq) + H2O(l) + CO2(g) there are:
4 hydrogen atoms
2 carbon atoms
6 oxygen atoms
As the building blocks of proteins , amino acids are linked to almost every life process, but they also have key roles as precursor compounds in many physiological processes.
C is the correct answer I think have a good day
Answer:
pH =6.70
Explanation:
When Kw = 1x10^-14
[H3O+] = [OH-] --> 1x10-7
Kw =3.98x^10-14
3.98x^10-14 = [H3O+] . [OH-]
√ (3.98x^10-14) = [H3O+] = [OH-]
[H3O+] = 1.99×10^-7
- log [H3O+] = pH ---> -log 1.99x10^-7 = 6.70
