Use the equation for density :
Density = mass / volume
Density = 120 / 480
Density = 0.25
Answer:
Oppositely charged particles attract each other. This attractive force is often referred to as an electrostatic force. An ionic bond is the electrostatic force that holds ions together in an ionic compound.

Answer:
It is either
Past volcanic eruptions leave marks on rocks near the volcano.
Past volcanic eruptions leave marks in the atmosphere.
My guess is C.
Explanation:
C + 2S → CS2 + 89.3 kJ
Moles of CS2 = 150.0 kJ x (1 mol CS2/89.3 kJ) = 1.680 mol CS2
MW of CS2 = (12.01 + 2x32.06) g/mol = 76.13 g/mol
Mass of CS2 = 1.680 mol CS2 × (76.13 g CS2/1 mol CS2) = 128 g CS2
