A     4

B     6

C     Be

D     10

E     22

F     Ne

Explanation:

From the given table, we can simply complete the given table by identifying the meaning of each column header.

  • Number of protons in an atom is the number of positively charged particles in the nucleus of the atom. Protons are positively charged particles in an atom.
  • The number of neutrons are the number of neutrally charged particles occupying the nucleus of an atom.
  • Atomic number is another term for the number of protons in an atom.
  • Mass number is the sum of protons and neutron in an atom.
  • The symbol of an element is used represent a particular atom.

 Mass number = number of protons + number of neutrons

  Atomic number = number of protons = number of electrons in atoms.

Light shining on solar cells produces a current that charges a solar calculator. Which model of light does this example support?
vodomira [7]

The  model of light does the example supports is the particle model.

<h3>What is the wave-particle duality model of light?</h3>

The wave-particle duality model of light is a model which suggests that light behaves both as a [article and as a wave.

The wave-like property is seen in its properties such as reflection, refraction, diffraction, etc.

The particle nature of light is seen in the photoelectric effect and the Compton effect.

Light shining on solar cells produces a current that charges a solar calculator is an example of the photoelectric effect.

Therefore, the model of light does this example support is the particle model.

How many grams is 0.125 moles of SiO2?
OleMash [197]
First, you need grams but you have moles.
Find out the total molar mass of SiO₂
Si = 28.085 g/mol Si
O₂ = 32 g/mol O₂
Add them together to get the molar mass
28.085 g/mol Si + 32 g/mol O₂ = 60.085 g/mol SiO₂
Multiply the molar mass of SiO₂ by the number of moles you have of the same substance:
60.085 g/mol SiO₂ × 0.125 mol SiO₂ =
7.51 grams SiO₂
