Answer:

Different ions of different elements (usually metals) make a flame burn with a characteristic color when introduced into the reaction zone; the different colors are caused by the different quantized energy levels of the electrons in the different atoms.

Discribe how continents and oceans are carried on tectonic plates

Vanyuwa [196]

This question seems to be very basic .the ocean is above the plate, the plate material is heavier than water (it being rock). That's pretty much all of it. The plates grind a little and new land pushes up at plate boundaries but this does not seem to be related. The heavier material is below and the lighter above, those being rock and water respectively.

Please help me answer this question! I don’t understand it at all!

pentagon [3]

The uncertainty principle is one of the most famous (and probably misunderstood) ideas in physics. It tells us that there is a fuzziness in nature, a fundamental limit to what we can know about the behaviour of quantum particles and, therefore, the smallest scales of nature. Of these scales, the most we can hope for is to calculate probabilities for where things are and how they will behave. Unlike Isaac Newton's clockwork universe, where everything follows clear-cut laws on how to move and prediction is easy if you know the starting conditions, the uncertainty principle enshrines a level of fuzziness into quantum theory.

How much faster does helium escape through a porous container than ozone?

otez555 [7]

According to Graham's Law ," the rates of effusion or diffusion of two gases are inversely proportional to the square root of their molecular masses at given pressure and temperature".

r₁ / r₂ =   $\sqrt{M2 / M1}$ ---- (1)

r₁ = Rate of effusion of He

r₂ = Rate of Effusion of O₃

M₁ = Molecular Mass of He = 4 g/mol

M₂ = Molecular Mass of O₃ = 48 g/mol

Putting values in eq. 1,

r₁ / r₂ =   $\sqrt{48 / 4}$

r₁ / r₂ =   $\sqrt{12}$

r₁ / r₂ = 3.46

Result:
Therefore, Helium will effuse 3.46 times more faster than Ozone.

a quantity of gas has a volume of 400.0 mL when confined under a pressure of 600.0mm Hg. what will be the new volume of the gas

Alex787 [66]

Answer:

1200 mL

Explanation:

Given data

Initial pressure (P₁): 600.0 mmHg

Initial volume (V₁): 400.0 mL

Final pressure (P₂): 200.0 mmHg

Final volume (V₂): ?

For a gaseous sample, there is an inverse relationship between the pressure and the volume. If we consider the gas as an ideal gas, we can find the final volume using Boyle's law.

$P_1 \times V_1 = P_2 \times V_2\\V_2 = \frac{P_1 \times V_1}{P_2} = \frac{600.0mmHg \times 400.0mL}{200.0mmHg}=1200 mL$
