Answer:
Option A = 14.19 atm
Explanation:
Given data:
Volume of gas = 2.50 L
Number of moles of gas = 1.35 mol
Temperature of gas = 320 K
Pressure of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will put the values in formula.
P × 2.50 L = 1.35 mol × 0.0821 atm.L/ mol.K× 320
P = 35.467 atm.L/ 2.50 L
P = 14.19 atm
Thus, option A is correct.
Answer is: carbon dioxide (CO₂) can affect the end point of the titration.
Carbon dioxide, or carbon(IV) oxide, reacts with water and form carbonic acid, which can affect the end point of the titration, because more base is needed for neutralization of partially neutralized stomach acid.
Balanced chemical reaction of carbon dioxide and water: CO₂ + H₂O → H₂CO₃.
Answer:
Explanation:
Atoms are the thing that make up molecules and compounds. Molecules contain two or more atoms and are held together by covalent bonds
