A density of a substance is constant. It is an extensive property, meaning it does not depend on the amount of substance because it is a ratio of mass to volume. No matter how much of each there is, they would always have a fixed ratio called density. For lead, the density is
Density = mass/volume
Density = 23.94 g/ 2.10 cm³
Density = 11.4 g/cm³
To know the answer, we determine the polarities of the solvent we have. Water is polar and gasoline is nonpolar. We remember that like dissolves like. Therefore, the answers are:
<span>table sugar = water
motor oil = gasoline
rubber from tire marks = gasoline
adhesive residue from a packing tape = gasoline</span>
Increasing because more is being forced into liquid phase
Answer:
Na
Explanation:
On the periodic table, the atomic radius of an atom typically decreases when going from left to right and increases when going from top to bottom.
It's a gaslike state of matter consisting of positively charged ions, free electrons, and neutral particles. A hot, energetic phase of matter in which the atoms are broken apart into positive ions and negative electrons that move independently of each other.
