Answer: periodic law.
Justification:
1) Although Mendeleev formulated the modern periodic table, ordering the elements according to their physical and chemical properties, there is not such law as Meneleev's Law.
2) The Pauli exclusion principle states that two electrons on an atom cannot have the same 4 quantum numbers, which drives to the fact that only two electrons can stay in the same orbital, each with opposite spin numbers.
3) Hund's rule states that the electrons with the same energy level will occupy the orbitals with the same spin before adding the electrons with the opposite spin.
4) Indeed the periodic law <span>states that the elements are arranged in order of increasing atomic number, and there is a
periodic repetition of their physical and chemical properties.</span>
Well I’m. Or to sure but it can’t be B because when you throw the ball the the kinetic energy is still increasing
Answer:
0.1105 moles per 130 ml
Explanation:
For 1 L (1000) of solution, no of moles are = 0.85
For 1 ml of solution, no of moles are = 0.85/1000 moles
For 130 ml of solution, no of moles are= 0.85/1000 x 130
= 0.1105 moles per 130 ml
Answer:
I'm not 100% sure,but I think its trigonal pyramidal
Assuming you are talking about the individual in space, Size and Weight changes in space due to the difference in gravity. Astronauts grow taller in space due to the micro-gravity they experience out of the earth's atmosphere.
It would not be:
Mass : Because mass is a measurement not dependent on gravity
Density : Astronauts do not blow out in bubbles once they leave the earth's atmosphere, therefore, we can deduct that density stays the same
