i think the answer is A. water flowing downhill and spinning turbines
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>
The answer is 4.04605 X 10^-25
Answer:
Explanation:
ΔTemp => 35⁰C(108K) increases to 57.9⁰C(330.9L) => increases volume (Charles Law)
Use the Kelvin Temperature values in a ratio that will increase the original volume.
ΔVol = 6.33L(330.9/108.0) => gives a larger volume. Using 108.0/330.9 would give a smaller volume and would be contrary to what the problem is asking.
ΔPress => 342 mmHg increases to 821 mmHg => decreases volume (Boyles Law)
Use the pressure values in a ratio that will decrease the original volume.
ΔPress = 6.33L(342/821) => gives a smaller volume. Using 821/342 would give a larger volume and would be contrary to what the problem is asking.
Now, putting both ΔTemp together with ΔPress => net change in volume. (Combined Gas Law)
ΔVol = 6.33L(330.9/108.0)(342/821) = 8.08L (final volume of gas).
___________________
This problem can also be worked using the combined gas law equation:
P₁V₁/T₁ = P₂V₂/T₂ => V₂ = P₁V₁T₂/T₁P₂
V₂ = [(342mm)(6.33L)(330.9K)]/[(108K)(821mm)] = 8.08L (final volume of gas)
