Answer:
A. The amount of energy needed to remove 1 mole of electrons from 1 mole of ground-state atoms or ions in the gas phase.
Explanation:
Ionization energy is the quantity of energy required to remove an electron in ground electronic state from an isolated gaseous atom or ion, resulting in a cation. kJ/mol is the expresion we use for this energy, it refers to the amount of energy it takes for all the atoms in a mole to lose one electron each.
Ionization energy can be used as an indicator of reactivity and can be used to help predict the strength of chemical bonds because the more electrons are lost, the more positive the ion will be and the harder it will be to separate the electrons from the atom.
I hope you find this information useful and interesting! Good luck!
Answer:
148 grams of relative atomic mass
Explanation:
magnesium atomic mass : 24
nitrogen : 14
oxygen : 16
24 × 1
14 × 1 × 2
16 × 3 × 2
24 + 28 + 80 = 148 grams
Dynamic equilibrium of a chemical system is reached when the rate of forward reaction equals to that of the the backward reaction.
Answer:
"Option B It acts on all objects all of the time.
Explanation:
"Gravitational force" is a kind of force that will attract any object with a mass. It is a "natural phenomenon" where all the things, including in planets in-universe, of mass or energy, are brought towards each other.
Like the earth’s gravity helps in giving weight to objects and the ocean tides are caused because of the moon’s gravity. The example of gravity force is the force with which sun holds together the gases in it.
