Answer: It would be malleable, solids, luster, conductors, reactive
Explanation:
The answer is D, because "Animals without a backbone are invertebrates."
Ppm = mass of solute mg / mass of solvent kg
0.008 * 1000 = 8.0 mg ( solute )
1000 / 1000 = 1.0 kg (solvent )
ppm = 8 / 1
= 8.0 ppm
hope this helps!
