The two main types of seismic waves are body waves and surface waves. Body waves are broken down into P waves (primary waves) and S waves (secondary waves).
P waves are the fastest and can move through solid rock and liquids. These waves are longitudinal waves.
S waves are slower and can only move through solid rock. These waves are transverse waves.
Scientists used P waves and S waves to determine that part of the core of the earth is liquid. When an earthquake happened, both waves could be detected near the earthquake center, but only P waves (which travel through solids and liquids) could be detected on the other side of the earth. That meant the S waves could not move through the liquid outer portion of the earth's core, while the P waves could.
Because you need oxygen in your blood stream and it revives cells as it travels through.
Answer:
Conservation of mass mean mass cannot be created nor destroyed
Explanation:
Answer:
3.228x10⁻⁴ moles of Na2S2O3 are required
Explanation:
In iodometry, the reaction of KIO3 with Na2S2O3 is:
KIO3 + 6 Na2S2O3 + 6H⁺ → KI + 3Na2S4O6 + 3H2O + 6Na⁺
<em>Where 6 moles of Na2S2O3 reacts per moles of KIO3.</em>
<em />
The moles of Na2S2O3 required to reach endpoint when 0.0000538 moles of KIO3 are:
0.0000538 moles of KIO3 * (6 moles Na2S2O3 / 1 mol KIO3) =
<h3>3.228x10⁻⁴ moles of Na2S2O3 are required</h3>
Physical Change because a new substance was not created and if it was a chemical change, a new substance would have to be created.
