Tsunami waves are almost the same as ripples caused by throwing a rock into a pond. What is the major difference between the two
Daniel [21]

c. The energy source of tsunami waves is much greater

Explanation:

The major difference between a tsunami waves and ripple waves is that the energy source of tsunami waves is much greater compared to ripple waves.

Tsunami waves carry more energy compared to just a disturbance resulting from a ripple caused by dropping of a stone.

  • A tsunami is a large water wave caused by the displacement of water usually by an earthquake.
  • An earthquake is a releases elastic waves suddenly within the earth crust.
  • Water bodies at the epicenter are disturbed sending huge volume of energetic water loads to the land.
  • A ripple is just a product of a stone dropped inside the water.

Tsunamis are more energetic compared to ripples in water.

You need to make 25 microliters of a 3M NaOh solution for a test reagent. Your laboratory routinely stocks 500 milliliters of a
MrRissso [65]

Answer:

0.0075 milliliters (7.5 microliters) will be taken from the stock solution and then diluted with 0.0249925 milliliters (24.9925 microliters) of water to make 0.025 milliliters (25 microliters) of NaOH solution.

Explanation:

This is a problem of dilution using the equation:

<em>initial concentration x initial volume = final concentration x final volume.</em>

The final volume to be prepared is 25 microliters.

The final concentration to be prepared is 3 M.

The initial volume to be taken is not known yet.

The initial concentration is 10 M.

Now, let's substitute these parameters into the the equation above.

10 x initial volume = 3 x 25

Initial volume = 3 x 25/10

     = 7.5 microliters

Note that: 1 microliter = 0.001 milliliters

Hence,

7.5 microliters = 0.0075 milliliters

<u>This means that an initial volume of 0.0075 milliliters (7.5 microliters) will be taken from the stock solution. This amount will then be diluted with 0.0249925 milliliters (24.9925 microliters) of water to make 0.025 milliliters (25 microliters) of NaOH solution.</u>
