Answer:

Atoms are composed of extremely small particles that are too small to be seen with an optical microscope.

Size at the atomic level is measured on the nanoscale.

Atoms are made of three subatomic particles - protons, neutrons, and electrons.

Protons:

  • positively charge
  • located in the nucleus

Neutrons:

  • no charge (neutraly charge)
  • located in the nucleus

Electrons:

  • negatively charged
  • located around the nucleus

Atomic number (Z) = the number of protons in the nucleus of an atom.

(i apologize, i don't understand the last part...)

Determine the mass in grams of each of the following:
lukranit [14]

Answer:

A) 9.60 g

B) 19.2 g

C) 28.8 g

Explanation:

A) Elemental oxygen mass is 16.00 g/mol, so in 0.600 mol of elementar oxygen there is 9.60 g

0.600 mol x 16.00 g/mol=9.60 g

B) Oxygen molecular mass is 32.00 g/mol, so in 0.600 mol of oxygen molecules there is 19.2 g

0.600 mol x 32.00 g/mol=19.2 g

C) Ozone molecular mass is 48.00 g/mol, so in 0.600 mol of oxygen molecules there is 28.8 g

0.600 mol x 48.00 g/mol=28.8 g

A certain liquid X has a normal boiling point of 111.20 celsius and a boiling point elevation constant Kb=0.95. calculate the bo
Goshia [24]

Answer: the boiling point is = 137.325°C

Explanation:

From the formula: ∆Tb= Kb*m

From the question, Kb= 0.95, m= 27.5, T1= 111.2°C

Substitute into ∆Tb= Kb*m

∆Tb= 0.95*27.5= 26.125

∆Tb= T2-T1

Hence

T2- 111.2=26.125

T2= 26.125+ 111.2= 137.325°C

Carbon has a neutral overall charge, an atomic mass of about 12 and an atomic number of 6. How many electrons does carbon have?
Artist 52 [7]
For the atom to be neutral, it must have the same number of electrons and protons. The aromic number indicates the number of protons. Since Carbon has 6 protons, it would have to have 6 electrons for it to be neutral
