Answer:
Chemical reaction
Explanation:
In chemical weathering, minerals that were stable inside the crust must change to minerals that are stable at Earth's surface. ... Many silicate minerals form in igneous or metamorphic rocks. The minerals that form at the highest temperatures and pressures are the least stable at the surface.

Explanation:
Alanine is an amino acid with the formula C3H7NO2. How many atoms in all are in each molecule of alanine?
Answer:
12
Explanation:
13 atoms in all are in each molecule of alanine.
To find the total number of atoms in one molecule of alanine, we count the atoms for each element in the chemical formula.
Alanine has the molecular formula [tex]C_3H_7NO_2[/tex]:
3 carbon atoms ([tex]C_3[/tex])
7 hydrogen atoms ([tex]H_7[/tex])
1 nitrogen atom (N)
2 oxygen atoms ([tex]O_2[/tex])
Adding them together, we get:
3 + 7 + 1 + 2 = 13 atoms.
Adding them together, we get 3 + 7 + 1 + 2 = 13 atoms in one molecule of alanine. These atoms are arranged to form the chemical structure of the alanine molecule, which is an essential building block of proteins in living organisms.
