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:
When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
Explanation:
When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
Answer: It is an exothermic process because heat energy is absorbed by the water as the NaOH(s) dissolves in it.
Explanation:
Endothermic reaction : It is a type of chemical reaction where the energy is absorbed from the surrounding. In the endothermic reaction, the reactant are less than the energy of product. In endothermic reaction, the change in enthalpy is, positive
Exothermic reaction : It is a type of chemical reaction where the energy is released into the surrounding. In the exothermic reaction, the energy of reactant are more than the energy of product. In exothermic reaction, the change in enthalpy is, negative.
Thus as energy is absorbed by water, which has been released by NaOH, the process is exothermic.
