a. Krish's container is heavier than Raunak's container.

b. Both container have the same number of atoms.

Explanation:

The molar mass of any element is equivalent to one mole of that substance.

weight of 1 mole of carbon atom is 12 g and weight of 1 mole of sodium atoms is 23 g.

So, the mass of 5 moles of carbon atoms

12 x 5 = 60 g

In this same way,

the mass of 5 moles of sodium atoms

23 x 5 = 115g

From this, we can say that Krishna’s container is heavier.

b. One mole of a carbon atom has 6.022 x 10^23 atoms and one mole of sodium also has 6.022 x 10^23 atoms.

So, 5 moles of carbon and sodium contains the same number atoms which are

5 x 6.022 x 10^23

= 3.011 x 10^24 atoms.

Sonar is a technology that uses sound waves to calculate the distance to an object. Explain why you think sonar is useful for sc
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.

The pKa of the α‑carboxyl group of serine is 2.21 , and the pKa of its α‑amino group is 9.15 . Calculate the average net charge
sleet_krkn [62]

Answer:

Net charge in serine at pH equal to 8.30 is "0"

Explanation:

  • At pH > pK_{a}, carboxyl group exists as -CO_{2}^{-} (charged)
  • At pH < pK_{a}, carboxyl group exists as -COOH (neutral)
  • At pH > pK_{a}, amino group exists as -NH_{2} (neutral)
  • At pH < pK_{a}, amino group exists as -NH_{3}^{+} (charged)
  • So, at pH = 8.30, both carboxyl and amino group exists in charged state.
  • Net charge in serine at pH equal to 8.30 is "0".
  • Structure of serine at pH equal to 8.30 has been shown below.
