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

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
