2 SO₃ --> 2 SO₂ + O₂
I 12 0 0
C -2x +2x +x
---------------------------------------------
E 12-2x 2x x
Since the moles of SO₂ at equilibrium is 3 mol, 2x = 3. Then, x = 1.5 mol. So, the amounts at equilibrium is:
SO₃: 12 - 2(1.5) = 9
SO₂: 2(1.5) = 3
O₂: 1.5
The formula for K basing on the stoichiometric reaction is:
K = [SO₂]²[O₂]/[SO₃]²
where the unit used is conc in mol/L.
K = [3 mol/3 L]²[1.5 mol/3 L]/[9 mol/3 L]²
<em>K = 0.0556</em>
From the chemical formula, 1 formula unit of KAl (SO4)2.12H2O
encompasses 1 atom of Al = 4 * 2 atoms of O in KAl (SO4)2 + 12 atoms of O in
12H2O which is equal to 20 atoms of O.
So, if you have 1.3 × 10^21 Al atoms, you have 20 * 1.3 × 10^21 O atoms will
now be equal to 2.6 * 10^22 atoms of O.
Answer:
- <u>Agents that can homogenize immiscible solutions are</u> milk , lotion , glue , paint ,alcohol etc.
- The primary difference between fats and oils is that, whereas oils are generally derived from plants, fats are usually derived from animals.
- Eating too much of the wrong kinds of fats will increase unhealthy LDL cholesterol of decrease healthy HDL cholesterol, such as saturated and trans fats.
- Your risk of high blood pressure, arterial hardening (atherosclerosis), heart attack and stroke may be enhanced by the imbalance of fats and oils.
- <u>Among the doctor and the patient , the patient's health is deteriorating. </u>
<u>To minimize the intake of fats and oils by suggesting them simple ways-</u>
- Eat more vegetables and fruits.
- Stop cream and cheese sauces, or use low-fat milk and cheese to make meals.
- Instead of butter or margarine, try cooking with herbs , spices, lemon juice, etc.
- Try cooking with herbs, spices, lemon juice, etc., instead of butter or margarine.
- Beware of confectionary foods, such as chocolate or pastry dishes and crisps. These are very high in fat instead consider swapping for a more balanced snack or restricting portion sizes.
<u>Explanation:</u> <u>FATS -</u>: Fats are usually derived from animals. Fats contain a larger proportion of fatty acids that are saturated. Fats at room temperature are solid.
<u> OILS -</u> Oils at room temperature are liquid. From plants, oils are extracted. A greater proportion of unsaturated fatty acids are found in oils.
Answer:
Atoms only share electrons in covalent bonds. covalent bonds are only formed between nonmetals. there are two different types of covalent bonds; polar and nonpolar. in a polar covalent bonds electrons are shared unequally because one atom has a stronger force of attraction than the other (EX. H2O). In a nonpolar covalent bond, the electrons are shared equally because they're electronegativity is also equal (EX. Cl2).
Overall, the atoms electronegativity determines the way it shares electrons
An Arrhenius base is a substance that increases the concentration of OH- ions in a water solution.
A base has a high pH, whereas an acid has a low pH and increases the concentration of H+ ions in a solution.
Hope this helps!
