They all have the same number of protons (12).
The number of protons (the atomic number) is the same for all atoms and ions of Na.
However, atoms and ions have different numbers of electrons.
An <em>Na atom</em> has 11 electrons, but an <em>Na^(+) ion</em> has only 10 electrons.
Answer: El Plasma, es el estado físico mas abundante no solo del universo sino de la naturaleza:
Explanation:
"El plasma es el estado de agregación más abundante de la naturaleza, y la mayor parte de la materia en el Universo visible se encuentra en estado de plasma, la mayoría del cual es el enrarecido plasma intergaláctico (particularmente el medio del intracluster) y en las estrellas."
Answer:
36.92 mg of oxygen required for bio-degradation.
Explanation:
Mass of benzene = 30 mg = 0.03 g (1000 mg = 1 g )
Moles benzene =
According to reaction 5 moles of benzene reacts with 15 moles of oxygen gas.
Then 0.0003846 mol of benzene will react with:
of oxygen gas
Mass of 0.0011538 moles of oxygen gas:
0.0011538 mol × 32 g/mol = 0.03692 g = 36.92 mg
36.92 mg of oxygen required for bio-degradation.
The statement above is true. He conducted the oil-drop experiment which lead him to determine the charge of the electron. He suspended charged droplets into an oil which is in between two electrodes and balancing the upward force with the downward forces.
