Which of the following is NOT a compound? H20 CO2 02 CO

This increase in blood pHpH due to hyperventilation disrupts O2O2 transport by causing the deprotonation of various residues of

Genrish500 [490]

The question is incomplete as it does not have the options which has been provided in the attachment.

Answer:

1. sudden decrease

2. Respiratory alkalosis

Explanation:

Hyperventilation is a condition caused by the excess removal of the CO₂ from the blood which leads to the decrease in the pCO₂ of the arteries.

This decrease can cause fainting and death of the individual due to the malfunctioning of the body parts, especially the brain.

The decrease in the CO₂ amount of the blood causes the formation of bicarbonate and H⁺ ions which leads to respiratory alkalosis.

Therefore the selected options are correct.

3. How would you expect the density of the gummy bear to change if you soaked it in isopropanol (rubbing alcohol, density

77julia77 [94]

Change occurs in the density of the gummy bear to change if we soaked it in isopropanol.

<h3>Effects on density by soaking isopropanol</h3>

We expect the density of the gummy bear to change if we soaked it in isopropanol because the gummy bear absorb the liquid which increase its density due to increasing weight of the gummy bear.

If a substance gains weight then its density also increases and we know that when the gummy bear was soaked in the isopropanol then its weight increases so its density is also changes so we can conclude that change occurs in the density of the gummy bear to change if we soaked it in isopropanol.

At 300.0 K and 0.987 atm pressure, what will be the volume of 2.30 mol of Ne?

Nadya [2.5K]

Answer:

V = 57.39 L

Explanation:

Given that,

Temperature, T = 300 K

Pressure, P = 0.987 atm

No. of moles of Ne, n = 2.30 mol

We need to find the volume of Ne. We know that, the ideal gas law is as follows :

PV = nRT

Where

P is pressure and R is gas constant

$V=\dfrac{nRT}{P}\\\\V=\dfrac{2.3\times 0.0821\times 300}{0.987 }\\\\V=57.39\ L$

So, the volume of the Ne is 57.39 L.

29. Ammonia is formed with one nitrogen and three hydrogen atoms. What is the electron configuration of nitrogen? How

masya89 [10]

Answer:

One lone-Pair is present in Ammonia

Explanation:

The number of valence electron in N = 5

The number of Valence electron in H = 1

The formula of ammonia = NH3

Total valence electron in ammonia molecule = 5 +3(1) = 5+3 = 8

The lewis structure suggest that :

Nitrogen completes its octet by sharing the electron pair with 3 hydrogen atoms.

3 electron of Nitrogen are involved in sharing with Hydrogen

So, remaining two electron are left non-bonded . Hence they exist as lone- pair

So, there is only 1 lone pair in the ammonia molecule .

The shape of NH3 is bent according to VSEPR theory . This is so because the presence of 1 lone pair causes more repulsion and occupy more space.

Thus the lone pair is changing the shape of the ammonia molecule . It also increase the dipole moment of the molecule , which gives polarity to it.
