Please help, I lost my previous tutor just when she was explaining the answer

Chemistry
1 answer:
TEA [102]3 years ago
5 0

Answer:

HCO₂/H₂O is not the acid-base conjugate pair.

Explanation:

<em>Acid and conjugate base pairs differ by an H+ ion.</em>

Neither HCO₂ nor H₂O has lost or gained protons.

The conjugate acid of H₂O is H₃O⁺

The conjugate base of HCO₃⁻ is CO₃²⁻

[A conjugate acid has one more H⁺ than its base]

The option that would be appropriate to model nuclear fission is disturbing a drop of water such that it breaks into smaller droplets

Nuclear fission refers to the splitting of a heavy nucleus into lighter nuclei owing to the bombardment of small particle.

The liquid drop model provides the most apt model for describing the concept of nuclear fission. In nuclear fission, the nucleus breaks due to the increase in repulsion between the nuclear charges.

As the size of the nucleus continues to increase, any little disruption will; result in the breaking up of the nucleus into smaller fragment called daughter nuclei.

Hence, the model of disturbing a drop of water such that it breaks into smaller droplets is the most apt description of nuclear fission.

8. At higher temperatures _______.
DanielleElmas [232]

Answer:

B. particles in an object move faster

Explanation:

At higher temperatures, particles in an object moves faster.

Temperature is the degree of hotness or coldness of a body.

  • At higher temperature, the substance is very hot.
  • Temperature is related to the heat energy content of a body
  • As the temperature increases, the average kinetic energy of the particles of system increases more and more.
  • This is in compliance with the kinetic molecular theory of matter.
  • Therefore, at higher temperatures, particles in an object move faster.
