I'm not sure where the question is here. Yes it is true that there is a limited amount of matter on Earth...
Answer:
6.4g
Explanation:
32g of O2 produce 36g of H2O/5.70g of O2 produce x the answer is 6.4g
Answer:
The answer to your question is D.
Explanation:
Potassium has 4 energy levels in the first level (A) has only 2 electrons,
in the second energy (B) level has 8 electrons, in the third energy level (C) also has 8 electrons and in the fourth energy level has only one electron.
Valence electrons are located in the outermost shell so Potassium has only one electron located in the shell D.
The false statement is C. According to the Heisenburg uncertainty principle, which inspired the modern 'Electron Cloud' model of the atom, it is nearly impossible to predict an electron's path around the atom. The model statement C is referring to is the Neils Bohr model of the atom, which is useful, but inaccurate.
