Just simply... they both are energy.
Use a bow and arrow as an example:
When you pull back an arrow, potential energy or PE is stored in the string and the limbs of the bow.
When you release the the arrow, energy is being transferred from the bow to the arrow. The arrow now has kinetic energy or KE, this means that the energy is being used by the arrow.
Answer:
Three of the five oxides are expected to form acidic solutions in water
Explanation:
We have different types of oxides : Acidic oxides, Basic oxides, Amphoteric oxides, Peroxides and Higher oxides.
Only acidic oxides will dissolve in water to give an acidic solution.
Considering the given oxides carefully,
- SO2 will dissolve in water to produce H2SO3 which is acidic.
- Y2O3 will dissolve in water to produce Yttrium(III) hydroxide which is basic.
- MgO will dissolve in water only to produce Mg(OH)2 which is also basic.
- Cl2O dichlorine mono oxide will dissolve in water to produce HClO which is acidic.
- N2O5 will dissolve in water to produce HNO3 which is also acidic.
Answer:
17.6% is the percentage error
Explanation:
The percentage error is used to determine accuracy of a measurement (That is, how closely is the measure to the real or theoretical value). The equation is:
|Measure - Real| / Real * 100
In the problem, the measure was 22.7cm³ and real value is 19.3cm³. Solving for percentage error:
|22.7cm³ - 19.3cm³| / 19.3cm³ × 100
<h3>17.6% is the percentage error</h3>
