Answer:
the answer should 126 859.2 m2
Answer:
Radioactive isotopes ranging from 11O to 26O have also been characterized, all short-lived. The longest-lived radioisotope is 15O with a half-life of 122.24 seconds, while the shortest-lived isotope is 12O with a half-life of 580(30)×10−24 seconds (the half-life of the unbound 11O is still unknown).
The concentration of the Nitric acid solution : 0.114 M
<h3>Further explanation </h3>
Titration is a procedure for determining the concentration of a solution (analyte) by reacting with another solution whose known concentration (usually a standard solution) is called the titrant. Determination of the endpoint/equivalence point of the reaction can use indicators according to the appropriate pH range
Titrations can be acid-base titration, depositional titration, and redox titration. An acid-base titration is the principle of neutralization of acids and bases
Reaction
HNO₃ + NaOH → NaNO₃ + H₂O
Concentration a standard solution of sodium hydroxide : 0.0998 mol/dm³ , and the volume = 25 cm³
moles NaOH=
<em>From the equation, mol ratio HNO₃ : NaOH = 1 : 1, so mol HNO₃ = mol NaOH=</em><em>2.495 mlmoles</em>
<em></em>
The volume of HNO₃ = 21.8 cm³, so the concentration :
Explanation:
Sorry, I don't know, but I can tell you that when an atom, or a body, has the same amount of positive charges (protons) and negative charges (electrons), it is said to be electrically neutral. ... The net charge corresponds to the algebraic sum of all the charges that a body possesses.
A. They are the most destructive earthquake waves.
D. They can move in a rolling pattern through rock, like an ocean wave.
Explanation:
Surface waves are seismic waves that cause the most destruction during an earthquake.
Rayleigh waves are known to cause rolling pattern of rocks just like an ocean waves.
- Seismic waves are elastic waves that notably transmits energy.
- They usually accompany earthquakes.
- There are two broad categories of these waves.
- Surface and body waves.
- Seismic surface waves are low frequency and long wavelength waves.
- They travel very close to the surface.
- They are made up of Love and Rayleigh waves.
- Love waves travels laterally in a horizontal fashion.
- Rayleigh waves rolls like ocean waves in the ground.
- The bulk of the destruction caused during an earthquakes is due to these waves.
- They are the last waves to arrive a seismic station
