A gas has a pressure of 3.16 atm at STP. I have decided to transfer it to a container that is 3 times larger than the original v
Oliga [24]

Answer:

<u>The new pressure is 1.0533 atm</u>

<u></u>

Explanation:

According  to<u> Boyle's Law :</u> The Pressure of fixed amount of gas is inversely proportional to Volume at constant temperature.

PV = Constant

P1V1 = P2V2

P_{1}V_{1}=P_{2}V_{2}.....(1)

P1 = 3.16 atm

Accprding to question ,

V1 = V

V2 = 3 V

Insert the value of V1 , V2 and P1 in the equation(1)

P_{1}V_{1}=P_{2}V_{2}

3.16\times V=P_{2}\times 3V

V and V cancel each other

3.16=P_{2}\times 3

P_{2}=\frac{3.16}{3}

P_{2}=1.05atm

What frequency is a wave with a wavelength of 1km?
ryzh [129]

The frequency of wavelength of 1km <u>299792.458 Hz.</u>

These molecules already react to the inward motion of the loudspeaker membrane moving toward the source. Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.

calculation:-

C= wavelength × frequency

frequency = 3 × 10⁸/ 1000 Hz

= 299792.458 Hz.

= 3 ×10⁵ Hz

Based on such a model, we found that mass is not an intrinsic property of the particle. Instead, mass is basically a measure of particle energy. The relations between energy and mass can be directly derived based on the wave properties of the particle. Waves are one of the ways in which energy may be transferred between stores. Waves can be described as oscillations or vibrations about a resting position.

In the following reaction 6.13 g of water is actually produced, but the theoretical yield of water is 8.17 g. What is the percen
CaHeK987 [17]

Answer:

75.0%

Explanation:

Data obtained from the question. This includes the following:

Actual yield = 6.13g

Theoretical yield = 8.17g

Percentage yield =...?

The percentage yield can be obtain by using the following formula:

Percentage yield = Actual yield /Theoretical yield x 100

Percentage yield = 6.13/8.17 x 100

Percentage yield = 75.0%

Therefore, the percentage yield of water from the reaction above is 75.0%
