What is the wavelength of the matter wave associated with an electron (me= 9.1 x 10-31 kg) moving with a speed of 2.5 x 107 m/s?

Novay_Z [31]

Lambda = h\ Mv
lambda = 6.624 x 10^-34 / 9.1 x 10^-31 x 2.5 x 10^7
lambda = 2.9 x 10^-11 is your wavelength

A gaseous mixture consisting of nitrogen, argon, and oxygen is in a 3.5-L vessel at 25C. Determine the number of moles of oxygen

Step2247 [10]

Answer:

Number of moles of oxygen = 0.037 mol

Explanation:

Given data:

Total pressure = 98.5 KPa

Partial pressure of nitrogen = 22.0 KPa

Partial pressure of argon = 50.0 KPa

Volume = 3.5 L

Temperature = 25°C (25+273= 298K)

Number of moles of oxygen = ?

Solution:

Total pressure = P(N₂) + P(O₂) + P(Ar)

98.5 KPa = 22.0 KPa +P(O₂) + 50.0 KPa

98.5 KPa = 72.0 KPa +P(O₂)

P(O₂) = 98.5 KPa - 72.0 KPa

P(O₂) = 26.5 KPa

KPa to atm:

26.5 KPa/ 101 = 0.262 atm

Number of moles of oxygen:

PV = nRT

n = PV/RT

n = 0.262 atm × 3.5 L / 0.0821 atm.L/mol.K × 298 K

n = 0.917atm.L /24.47atm.L/ mol

n = 0.037 mol

Which of these describes an ethical dilemma that drug designers could face?

LenKa [72]

The statement 'whether people should take medicine or if they should seek alternative treatments' describes an ethical dilemma that drug designers face.

<h3>What is drug development?</h3>

Drug development refers to all the processes from target drug identification to drug validation and commercialization.

Drug development involves different stages of development including preclinical and clinical trials.

Ethical dilemmas in drug development include the release of a drug that is ineffective when compared to parallel treatments.

A student performs an experiment to determine the melting point of ice in order to investigate the strength of electrostatic for

andrezito [222]

Once the student has finished his experiment, additional steps he may take are to analyze the data gathered and draw a conclusion, then publish his findings to be seen by his peers (other students).

<h3 /><h3>What comes after the experiment?</h3>

Once an experiment is concluded, one must go over the data gathered.
By this, we mean to analyze the information obtained through the experiment.
This allows the student to draw a conclusion backed by evidence.
Once complete, it is wise to share and discuss the findings with peers.

Therefore, we can confirm that once the experiment is completed, the most common action that follows is to draw a conclusion based on the analysis of the data gathered during the experiment, then discuss the findings with peers.
