Answer: protons and electrons
Explanation: In a neutral atom there are always equal numbers of protons and electrons.
<span>Recordings of seismic waves from earthquakes led to the discovery of the earth's core and eventual maps of the layers of the Earth's inside. Just as the prism below refracts light at its faces, seismic waves bend, reflect and change speed at the boundaries between different materials below the Earth's surface.

Answer:
Molar mass of acetic acid is 60 g/mol
Explanation:
Look at the formula:
CH₃COOH
We have:
- 2 moles of C → 12.011 amu . 2 = 24 g/mol
- 4 moles of H → 1.008 amu . 4 = 4 g/mol
- 2 moles of O → 15.999 amu . 2 = 32 g/mol
Let's sum the mass of each element
24 g/mol + 4 g/mol + 32 g/mol = 60 g/mol
Answer:
<span>diffusion because particles move from regions of high concentration to regions of low concentration.
Difusión refers to the movement of the particles through a material. The driven force for the diffusion is the gradient (difference) of concentration.
Diffusion, for example, is what happens if you open a bottle of perfume in a corner of your bedroom and later the smell fills all the room. The particles will spread along all the space until the concentration of the perfume in uniform.
