Margarita [4]

Answer:

<em>Sonar can be used to measure the depth of the seabed or the distance of any object, animal or a man-made vessel any other objects </em>

Explanation:

A sound wave or sound pulse is projected into the water.

If any object tends to come in the way of the pulse, an echo is produced or the signal is reflected back.

A transducer measures the strength of this signal and hence determines the depth of the object or the sea.

This is much better way of measuring distances under the sea since light alone is not able to pierce through the ocean after a certain distance.

A powerful sonar blast can help in taking multiple measurements at a time, while even a laser will find it difficult to reach below 3 km of depth.

Suppose that you are performing a titration on a monoprotic acid. Titration of this monoprotic acid required a volume of 0.1L of

Alex73 [517]

Answer: A) More base is likely required to reach the endpoint for the diprotic acid than for the monoprotic acid under these conditions

Explanation:

The monoprotic acid (HA) has a valency of 1 and diprotic acid $(H_2A)$ has a valency of 2.

As the concentration and volume of the diprotic acid and the monoprotic acids are equal.

The neutralization reaction for monoprotic acid is:

$HA+BOH\rightarrow BA+H_2O$

The neutralization reaction for diprotic acid is:

$H_2A+2BOH\rightarrow B_2A+2H_2O$

Thus more number of moles of base are required for neutralization of diprotic acid and thus the volume required will be more as concentration and volume of the diprotic acid and the monoprotic acids are equal.
