Answer:
Explanation:
This is a direct application of the equation for ideal gases.
Where:
- P = pressure = 1.25 atm
- V = volume = 25.2 liter
- R = Universal constant of gases = 0.08206 atm-liter/K-mol
- T = absolute temperature = 25.0ºC = 25 + 273.15 K = 298.15 K
- n = number of moles
Solving for n:
Substituting:
Answer:
Vinegar is acidic => acetic acid (HC₂H₃O₂)
Explanation:
Vinegar consists of acetic acid (HC₂H₃O₂), water and trace amounts of other chemicals, which may include flavorings. The concentration of the acetic acid is variable. Distilled vinegar contains 5-8% acetic acid.
<span>0.38
You first calculate the total moles by dividing the grams by molecular weight:
45 g N2 / 28.02 g/mol = 1.6 mol N2
40 g Ar / 39.95 g/mol = 1.0 mol
Then you divide the moles of Ar by the total number of moles:
1.0 / (1.6 + 1.0) = 0.38 mol fraction</span>
Based on the observations from, the substance that water is more attracted to are polar substances.
<h3>
What is the Polarity of water?</h3>
Water is a compound made up of 2 atoms of hydrogen and 1 atom of oxygen.
Water molecule is polar due to the unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule.
Since water molecules are polar, they are more attracted to molecules that are also polar.
Thus, based on the observations from, the substance that water is more attracted to are polar substances.
