I believe your answer would be the 3rd one
Answer:
The following are the four unusual characteristics of water due to hydrogen bonding:
1. Water exhibits high specific heat as the presence of hydrogen bonds enhances the concentration of energy needed for the molecules to accelerate the speed, thus, elevating the specific heat.
2. Water has both high melting and high boiling points as hydrogen bonds enhance the energy, which is needed at the time of phase change, thus, increasing both the melting and the boiling points.
3. The hydrogen bonds present in the water gives rise to robust intermolecular attractions, therefore, enhancing the surface tension.
4. The hydrogen bonds present in the water makes the water to exhibit high heat of vaporization, that is, of about 41 KJ/mol.
Answer:
The pH is approximately: 2.1549
Explanation:
pH = - log(0.007)
Atoms with neutrons, protons, and electrons. Only the neutron has no electrical charge; protons and electrons are the other particles that are electrically charged.
<h3>What do you know about atoms? explain.</h3>
The smallest component of ordinary stuff that makes up a chemical element is an atom. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma. Atoms are incredibly tiny, measuring typically 100 picometers across. Due to quantum effects, they are so small that it is impossible to predict their behavior with sufficient accuracy using classical physics, as would be the case, for example, if they were tennis balls.
Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. The nucleus of an atom contains more than 99.94% of its mass. The electric charges of the protons are positive, those of the electrons are negative, and those of the neutrons are zero. The atom is electrically neutral if the number of protons and electrons is equal.
