What are some examples of chemical weathering(select all that apply):

reactions between air, water and minerals, chemicals in rain water

I think it's the first one (A) Reactions between air, water, and mineral's

Explanation:

Hope this helps am doing a test about it too. i'll let you know if it was right. :)

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
