Which diagram shows a wave with the highest frequency? Chemistry question.

notsponge [240]

The correct answer is D

Explanation:

Wave frequency is mainly determined by the number of waves that pass through a specific point. In a diagram, this can be found by analyzing the number of crests (top of the wave) and the space between them. For example, wave B is the one with the lowest frequency because there is only one crest and this shows only one wave passing at a specific point. On the opposite, wave D is the one with the highest frequency because this shows multiple crests and this indicates the frequency is high or that many waves pass through a specific point in a short time.

The modern atomic model is sometimes called the ________ or quantum mechanics model

Marat540 [252]

I believe the correct answer from the choices listed above is option D. The modern atomic model is sometimes called the electron cloud or quantum mechanics model. It <span>uses complex shapes of orbitals (sometimes called electron clouds), volumes of space in which there is likely to be an electron. </span>
Hope this answers the question. Have a nice day.

The solubility of co in water at 0c and 1 atm co pressure is 0. 0354 mg of co in 1 ml of water. Calculate the moalrity of aqueso

Dmitriy789 [7]

From all the calculations that were carried out, the concentration of 2atm is 0.0026 M.

<h3>What is molarity?</h3>

The term molarity is defined as the number of moles divided by the volume of the solution. Using the formula; C = kp where

C = concentration
k = constant
p = pressure

C = 0. 0354 * 10^-3 g/28 g/mol × 1000/1 L

C = 0.0013 M

k = C/p = 0.0013 M/1 atm

k = 0.0013 Matm-1

Now;

C = 0.0013 Matm-1 * 2 atm

C= 0.0026 M

a teacher divides her class into groups and assigns each group a task of measuring the mass of the same object three times.the t

RoseWind [281]

Answer:

This question lacks options, the options are:

A. Group C: 32.1 g, 35.0 g, 25.0 g

B. Group B: 25.5 g, 25.0 g, 24.8 g

C. Group A: 28.5g, 28.4 g, 28.5 g

D. Group D: 20.0 g, 25.0 g, 30.09

The answer is C. GROUP A

Explanation:

Precision in measurements refers to the degree of closeness between the repeated or measured values irrespective of how close they are to the true or accepted value, which is 25g in this case.

The precision of a measurement can be determined by simply finding the range (highest - lowest) of the measurements. The lowest range represents the most precise. The measurements for each group are:

Group C: 32.1 g, 35.0 g, 25.0 g

Range = 35.0 - 25.0 = 10g

Group B: 25.5 g, 25.0 g, 24.8 g

Range = 25.5 - 24.8 = 0.7g

Group A: 28.5g, 28.4 g, 28.5 g

Range: 28.5 - 28.4 = 0.1g

Group D: 20.0 g, 25.0 g, 30.09

Range = 30.09 - 25.0= 5.09g

Based on the ranges of the measurements in each group, one would notice that Group A has the lowest range (0.1g), hence, GROUP A is the most precise.
