Answer:
Balanced chemical equations only show formulae, not names. A balancing number, written in normal script, multiplies all the atoms in the substance next to it.
Answer:
Yes, it does not have chemical properties.
Explanation:
Helium, as an inert element, cannot rearrange its electrons to form another chemical substances with another element, like a combustion or an acidification, even though it can form nuclear reactions, these are not considered chemical reactions, because it does not involve a rearrangement of the electrons but changes the nucleus of the element giving another elements.
The electron will move from the first energy level to the second energy level.
The energy level closest to the nucleus is the first energy level, and when an electron absorbs a photon, it absorbs the energy in the photon. This absorption causes the electron to move from the first to second energy level.
Answer:
solvent = substance that can dissolve other substances
solute = substances that are dissolved
Answer:
2.138 x 10^26 atoms Na
Explanation:
atoms Na = 355 mol Na x (6.022 x 10^23 atoms Na/1 mol Na) = 2137.81 x 10^23 atoms Na = 2.138 x 10^26 atoms Na
