Ответ:
B
Explanation:
B leaves tiny stinging barbs, which since it's on leaves, prey wouldn't expect it because it would blend in with the environment. C has thorns that would pierce the skin, I'm guessing that it would be visible to prey.
Correct me if I'm wrong :')
Ответ:
n = grams / molar mass
molar mass of C13H18O2:
13*12g/mol + 18*1g/mol + 2*16g/mol = 206 g/mol
n = 13 g / 206 g/mol = 0.063 mol
b) number of atoms = Avogadro number * n = 6.022*10^23 atom/mol * 0.063 mol = 0.379 * 10^23 atoms = 3.8 * 10^22 atoms
