Question

a student investigated some properties of lead and recorded the findings below. which statement is true with respect to the investigation?

property	observation
density	11.3 g/cm3
volume of sample	3.00 cm3
melting point	327°c
reaction with air	lead oxide forms on the surface
electrical conductivity	conducts some electricity

o the student investigated only the physical properties of lead.
o the student investigated only the chemical properties of lead.
o the student investigated more physical properties than chemical properties.
o the student investigated more chemical properties than physical properties.

Explanation:

Physical properties include color, density, volume, melting - point, and electrical conductivity. Chemical property is the reaction with air. There are 5 physical properties and 1 chemical property.

Answer:

The student investigated more physical properties than chemical properties.
