C. The reaction goes from one of less moles to more causing it to be more disordered and therefore have a positive change in s
CuCl2 + 2NaNO3 ----> Cu(NO3)2 + 2NaCl
using molar masses:-
Theoretical yields:-
63.54 + 2(35.45) g of CuCl2 produces 2(22.98 + 35.45) g of NaCl
134.44 g .................................................... 116.86 g
31.0 g ....................................................31.0 * 116.86 /134.44=26.95g
So percentage yield is 21.2* 100 / 26.95 = 78.7% to nearest tenth

Image C is adhesion stronger and Image D is cohesion stronger
Answer:
B:Metamorphic
Explanation:
Rocks formed under high heat and pressure is essentially the definition of metamorphic rock :)
