You collect a sample of gases from an indoor pool area. The sample contains air and water vapor. The total pressure is 100.18 ki
nikitadnepr [17]

Here we have to choose the partial pressure exerted by the air in the given sample among the given options.

The partial pressure of the air in the sample is C. 96.82 kPa.

As per the Dalton's law of partial pressure the total pressure of the gas in the pool (P) is equivalent to the summation of the partial pressure of water vapor and air pressure.

Mathematically we may write:

P_{Total}= P_{water vapor} +  P_{Air}

Now the P_{Total} = 100.18 kilopascalsP_{water vapor} = 3.36 kilopascals.On plugging the values:100.18 kilopascals = 3.36 kilopascals + P_{Air}

Or, P_{Air}[/tex] = (100.18 - 3.36) kilopascals

Or, P_{Air}[/tex] = 96.82 Kilopascals.

Thus the partial pressure of the air in the sample is C. 96.82 kPa.

Draw four possible Lewis structures of the molecule xenon trioxide, XeO3, one each with zero, one, two, or three Xe−O double bon
algol [13]

Answer:

See the image below  

Explanation:

To draw a Lewis structure of a molecule, you place the least electronegative atom (Xe) as the central atom, with the more electronegative atoms (O) surrounding it.

Then you distribute the electrons around the atoms, giving every one an octet and placing any extra electrons on the central atom.

This procedure gives you four possible Lewis structures, so the actual structure is a resonance hybrid of them all.

Structure D has no formal charges, so it is the major contributor.

pickupchik [31]
The heart is protected from the bones by the rib cage or the thoracic cage. It protects both the heart and the lungs. The rib cage is composed of 12 pair of ribs, the sternum and thoracic vertebrae. All ribs are connected to the thoracic vertebrae. The rib cage also do not only protect the heart and lungs but also support the body and aid in respiratory function.
