Answers

Answer 1

Answer:

.0987 moles

Explanation:

Ideal gas law     PV = n RT       R = .082057 L-atm/mol-K

7 ( .347) = n (.082057) (300)       n = .0987 moles

Which of the following is true about amplitude?
A. The smaller the amplitude, the greater the energy that is carried by the wave.
B. The larger the amplitude, the less the energy that is carried by the wave.
C. The larger the amplitude, the more the energy that is carried by the wave. 72​

Answers

Answer:

C.

Explanation:

The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases. ... As the amplitude of the sound wave increases, the intensity of the sound increases. Sounds with higher intensities are perceived to be louder. Relative sound intensities are often given in units named decibels (dB).

The correct statement about the amplitude of a wave is option C. Thus, the larger the amplitude, the more the energy that is carried by the wave.

What is amplitude?

Amplitude of a wave is a parameter describing the intensity of the wave. Amplitude of a transverse wave and sinusoidal waves are measured as the distance between from the central point of a crest to its top or the the distance from the central point of the trough in the line to its bottom part.

The amplitude of a wave is directly proportional to the frequency of the wave and the frequency in turn is directly proportional to the energy of the wave.

Therefore, The correct statement about the amplitude of a wave is option C. Thus, the larger the amplitude, the more the energy that is carried by the wave.

What is the density (g/L) of 5.0 moles of NH3, at 1.18 atm and 25.0°C?

Answers

Answer:

.821 g/L

Explanation:

It does not matter what the gas is, just the number of moles to calculate volume....

Ideal Gas Law :  

PV = n R T       R = gas constant = .082057 L-atm/(mol-K)  &  T in Kelvin units

(1.18)(V) = 5 * .082057 * (25 + 273.15)

V = 103.67 Liters

NOW ...to calculate density, the gas  IS important...

  mole weight of NH3  (from periodic table) =  17.031 gm/mole

Density =  mass / volume    =    (5 * 17.031) / 103.67 L = .821 gm/L

Calculate the molar mass of 20.0 L of a gas at STP with a mass of 10.0 g. (STP = 273 K and 1 atm)

Answers

The molar mass of the compound with 20 l volume of gas with mass of 10.0 g. is 160.51 M.

What is molar mass?

Molar mass of many compounds can be calculated by dividing the mass of the compound by the number of moles of the compound.

Calculating the moles

Convert Kelvin into Celsius

[tex]\rm PV = nRT\\1 atm. \times 20.0 \times = n \times 8.314 \times 0.15 \circ C\\n = 0.0623[/tex]

Calculating the molar mass

[tex]\rm Molar\;mass = \dfrac{mass}{number\;of\;moles} \\\\Molar\;mass = \dfrac{10.0 }{0.0623} = 160.51 M[/tex]

Thus, the  molar mass of the compound is 160.51 M.

1. What makes a "fluorescent" highlighter marker so bright?

2. How does plasma make a campfire flame orange?

3. Why are crystals rare?

Answers

Answer:

1. What makes a "fluorescent" highlighter marker so bright?

When light of a certain wavelength is directed at the molecule's chromophore, a photon is absorbed and excites an electron to a higher energy state. Fluorescent highlighter ink is unusually bright because it converts some of the incident ultraviolet light that is invisible to humans into visible light.

2. How does plasma make a campfire flame orange?

The de-excitation of plasma (charged gas) is not the source of the light given off by a campfire's flame. The incandescence of solid soot particles billowing up on an updraft of hot air is what creates the light seen as a flame.

3. Why are crystals rare?

The answer is twofold: erosion and mixed composition. Wind, rain, and water flow have a way of knocking and mixing around things here on earth

Why does the equilibrium of a system shift when the pressure is decreased?

To maximize the stress on the system
To stop restoring equilibrium to the system
To increase the total moles of gas in the system
To decrease the total moles of gas in the system

Answers

When the equilibrium of a system shift to increase the total moles of gas in the system, when the pressure is decreased.

What is equilibrium law?

Equilibrium law states that when any external stress is applied on the equilibrium state of the reaction then reaction will shift towards that side where external stress decreases.

Relation between pressure and moles of gas is directly proportional to each other. So when pressure is decreased then to maintain the equilibrium total moles of the gas of the system will increases as a result of which pressure increases.

Hence, equilibrium shift to increase the total moles of gas in the system.

Answers

The new pressure of the gas would be 599.03 kilopascals

Boyle's laws

Boyles postulated that the pressure of any gas would be inversely proportional to its volume if the temperature of the gas remains unchanged.  

Mathematically: P1V1 = P2V2

In this case, P1 = 105 kilopascals, V1 = 2.031 liters, V2 = 0.356 liters.

P2 = P1V1/V2 = 105 x 2.031/0.356 = 599.03 kilopascals

Thus, the new pressure will be 599.03 kilopascals.
