Mica and feldspar are chemically weathered into: sand grains clay minerals limestone calcium carbonate

The answer would A. Sand grain I got 100 on the sedimentary assignment.

sand grains and clay minerals.

Explanation:

Mica is a sheet of silicate minerals from a group of minerals that are closely related in chemical structure. Feldspar are a group of minerals that usually form rocks. Which is why they take up about 41% of the Earth's crust. When both of these are chemically weathered they create sand grains and clay minerals.

I hope this answered your question. If you have any more questions feel free to ask away at

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
