Answer: create more healthy products for the soil and animals
Explanation:
ZnO + 2HNO₃→ Zn(NO₃)₂ + H₂O
mol Zn(NO₃)₂ = mol ZnO = 0.2 (from the coefficient)
mass Zn(NO₃)₂ = 0.2 x 189 = 37.8 g (theorethical yield)
% yield = 15.3 : 37.8 x 100% = 40.48%
6+2=115 and its good it took test
Answer:
the water is warmer in temperature than the ice cube
Explanation:
the cube wouldn't melt if the water was colder or equally cold (eventually the water would equalize to the room temp) but for a while the water would have to be colder than the cube for the ice cube to stay in a solidified form
