I think the correct answer among the choices listed above is option B. Silicon oxide is the solid that contains two types of bonds because you have Si-Si bonds and Si-O bonds. That is two different covalent bonds. Hope this answers your question.

The gas that a diver breathes must be maintained at a partial pressure of 0.20 atm of oxygen. More oxygen could poison the diver

Nimfa-mama [501]

<u>Answer:</u> The partial pressure of helium gas is 0.80 atm

<u>Explanation:</u>

Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.

To calculate the partial pressure of helium gas, we use the law given by Dalton, which is:

$P_T=p_{He}+p_{O_2}$

We are given:

Total pressure of the cylinder, $P_T$ = 1.00 atm

Vapor pressure of oxygen gas, $p_{O_2}$ = 0.20 atm

Putting values in above equation, we get:

$1.00=p_{He}+0.20\\\\p_{He}=1.00-0.20=0.80atm$

Hence, the partial pressure of helium gas is 0.80 atm

Which effect can you observe when the starting K2Cr2O7is diluted? Does the position (lambda) of the maximal absorption peaks cha

Marianna [84]

After the dillution of the solution, the wavelength of maximum absorption is decreased.

<h3>What is the wavelength of maximum absorption?</h3>

The wavelength of maximum absorption is the wavelength at which the solution absorbs the maximum amount of light. It is usually shown as a hump in the spectrum.

When the starting concentration of the K2Cr2O7 is diluted, the wavelength of maxium absorption decreases.
