At STP, 1 mol of gas occupies 22.4 L.
mol O2 = 68.5 L * 1 mol/22.4 = 3.06 mol
The answer is that there are 3.06 mol of oxygen gas at STP.
Emphysema can lead to respiratory acidosis acid/base disturbance.The compensated respiratory acidosis is typically the result of the chronic condition , the slow nature of onset giving the kidney time to compensate.
If the primary acid-base disorder is from respiratory , then the kidneys will compensate. If the primary acid-base disorder is from metabolic cause, then the lungs will compensate.The respiratory compensation can be begin within minutes and becomes maximal in 12-24 hours
The respiratory acidosis occurs when breathing out does not get of enough . The increased that remains results in overly acidic blood. This can results from respiratory problems.

Answer:
We have 1.69 moles of gas inside the balloon
Explanation:
Step 1: Data given
Volume of the balloon = 18.9 L
Temperature = 27.1 °C = 300.25 K
Pressure in the balloon = 2.20 atm
Step 2: Calculate the number of moles
p*V = n*R*T
n= (p*V)/(R*T)
⇒with n = the number of moles of gas
⇒with p = the pressure of gas = 2.20 atm
⇒with V = the volume of the gas = 18.9 L
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature = 27.1 °C = 300.25 K
n = (2.20 * 18.9) / ( 0.08206*300.25)
n = 1.69moles
We have 1.69 moles of gas inside the balloon
610.864 Energy result in kilojoules:
Answer : The correct option is, (4) one; five
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The representation of valence electrons of an atom by dots around the symbol of an element is said to be the Lewis-dot symbol.
In the representation of Lewis-symbol, one electron dot must put on each side of the element symbol then paired the electrons.
As per information, element A has 1 valence electron and element B has 5 valence electrons.
Thus, the valency of A is one and B is five.
