It would have a solubility substance and surface
On a molecular level there is a lot of movement which in turn is the reason why heat is generated.
Answer:
The modern model recognizes particles in the atom, whereas Dalton’s model does not.
Explanation:
The modern model considers the atom to consist of electrons, protons, and neutrons.
A is wrong. The modern model of the atom is widely accepted.
B is wrong. Dalton assumed that all atoms are identical. The modern model recognizes that there are isotopes of atoms.
D is wrong. The modern model explains emission spectra. Dalton's model does not.
Answer:
7.0 g/mL.
Explanation:
- Density is a characteristic property of a substance.
- The density of a substance is the relationship between the mass of the substance and the volume it takes up.
<em>d = m/V,</em>
where, d is the density of the metal,
m is the mass of the metal (m = 147 g),
V is the volume that the metal takes up (V = 41.0 mL - 20.0 mL = 21.0 mL).
<em>∴ d = m/V</em> = (147 g)/(21.0 mL) =<em> 7.0 g/mL.</em>
