What geologic processes are happening in the Lassen Volcanic National Park? Is it still being built up or taken away?
JulsSmile [24]

In May 1915, Lassen Peak, California, the southernmost active volcano in the Cascade Range, erupted explosively. Avalanches, mudflows, and flows of hot ash and gas devastated nearby areas, and volcanic ash fell as far away as 200 miles to the east. The Lassen area remains volcanically active, and the volcano hazards demonstrated in 1915 still can threaten not only nearby areas but also more distant communities. Recent work by scientists with the U.S. Geological Survey (USGS) in cooperation with the National Park Service is shedding new light on these hazards.

How is a compound different from an element 2.3 lesson check?
zavuch27 [327]

<em>Answer:</em>

  1. Element: Element are pure substance consist of same type of atoms
  2. Compound: Form by combination of atoms of different elements.

<em>Distinguish features:</em>

  • Compounds represented by chemical formula while elements are represented by symbols.
  • Compounds have fixed ratios of atoms of different elements while in elements are distinguished by atomic no.
  • Compounds can be converted into simple substance by chemical methods but the elements cant be converted into simpler substance by means of chemical methods.

<em>Example:</em>

  • Water (H2O) is a compounds.
  • Iron (Fe) is an element.

<em>Summary:</em>

  • When two or more elements are mixed then compounds are formed.

What is the freezing point of a solution containing 4.78 grams naphthalene (molar mass = 128.2 g/mol) dissolved in 32.0 grams pa
tester [92]
This is a freezing point depression problem, so it will use the equation:

ΔT = i Kf<span> m
</span>
i = 1 (naphthalene does not dissociate further when dissolved)
Kf = 7.10 C/m (a constant for paradichlorobenzene, which you'd be given)
m = moles of solute / kg of solvent; moles of solute = 4.78 / 128.2 = 0.0373; kg of solvent = 0.032; m = 0.0373 / 0.032 = <span>1.166m

</span>ΔT = 1 x 7.10 x 1.166 = 8.279 C

This means the normal freezing point of pure paradichlorobenzene is decreased by 8.279 C; the normal freezing point (again, something you'd be given) is 53.5 C, so the new freezing point would be 53.5 - 8.279 = 45.221 C.

A SCUBA tank can normally hold 18 liters of gas at 3000 psi. How many liters of gas would this be equivalent to if the gas were
NikAS [45]

Liters of gas at 14.7 psi: 3674 L

Explanation:

We can solve this problem by using Boyle's law, which states that:

"For an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"

Mathematically:

pV=const.

where

p is the gas pressure

V is its volume

This law can also be rewritten as

p_1 V_1 = p_2 V_2

Where:

p_1 = 3000 psi is the initial pressure of the gas

V_1 = 18 L is the initial volume of the gas

p_2 = 14.7 psi is the final pressure of the gas

V_2 is the final volume

Therefore, we can calculate the volume of gas corresponding to 14.7 psi of pressure:

V_2=\frac{p_1 V_1}{p_2}=\frac{(3000)(18)}{14.7}=3674 L
