Answer:
finding the mass percentage oven element in a compound might sound complicated, but the calculation is simple. For example, to determine the mass percentage of hydrogen in water H2O, divide the major mass of hydrogen by the total molar mass of water and then multiply the result by 100
Mixing equal amounts of a strong acid with a strong base also produces a neutral pH (pH = 7) solution<span>.
</span>A neutralization reaction<span> is when an acid and a base</span>react<span> to form water and a salt and involves the combination of H</span>+<span> ions and OH</span>-<span> ions to generate water. The </span>neutralization<span> of a strong acid and strong base has a pH equal to 7.</span>
the concentration of oxygen will be
concentration = K X partial pressure
K = Henry'a law constant = 2.28 × 10-3 mole/latm
Partial pressure of O2 = 0.21 (in atmosphere)
Concentration = 2.28 × 10-3 mole/latm X 0.21 = 4.788 X 10^-4 mol /L
Why Triglyceride is important for human?
- Triglycerides store unused calories and provide your body with energy. Cholesterol is used to build cells and certain hormones.
