What kind of chemical bond is found between paired bases of the dna double helix?
zimovet [89]
Hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.

Why does hydrochloric acid have a higher boiling point than diatomic fluorine? The stabilizing effect of dipole interactions in
il63 [147K]
The correct answer would be the fourth option. Hydrochloric acid has a higher boiling point than fluorine molecule because the former is a polar molecule which means that it has stronger bonds than fluorine which is a non-polar molecule. Stronger bonds require more energy to break these bonds.

The kinetic molecular theory (KMT) deals specifically with
fgiga [73]
This kind of questions cannot be open because there might be many different answers depending of the focus.

In fact, I found the set of options that comes with this questions. This is:

A. behavior of ions.
B. molecular bonding.
C. molecular shape.
D. molecular motion.

Of course, the answer is the option D. molecular motion.

And, of course, you need an explanation.

It is good to know that the word kinetic refers to motion, so definetly kinetic molecular theory is a theory about the motion of the molecules.

With that you likely had been able to answer the question. But it is good to know what the molecular theory is.

The molecular kinetic molecular theory explains the properties and behavior of the gases in terms of the motion of its particles (molecules) making several assumptions about the energy, size and motion of such particles.

Select ALL correct answers. The contact force is caused by: A. Atoms randomly crashing into each other B. The charged particles
Inessa [10]

Answer:

A. Atoms randomly crashing into each other

E. The force of one object pushing against the force of another object.

Explanation:

Forces can be classified into two categories based upon the the mode of transfer or application:

1. Contact forces

2. Non-contact forces

Contact forces are the ones which require the physical contact of the matter to get transferred and tend to create the affect. Whereas non-contact forces have the field property which transfers the affect of force from one point to another without any physical contact of the matter or the medium.

  • Atoms crashing onto each other have some mass and velocity which upon collision impacts the other atoms exerts a contact force.
  • The interaction between the charged particles due to their charges is always due to the electric field be it electron or proton, be it within an atom or out of an atom.
  • The force between any two objects pushing or pulling each other is also possible only due to contact.

In a 0.20 M solution, a weak acid is 3.0% dissociated.(a) Calculate the [H₃O⁺] , pH , [OH⁻], and pOH of the solution.
marin [14]

H₃O⁺ = 6.0×10^{-3}

OH = 1.7×10^{-12}

pH = 2.22

pOH = 11.78

<h3>What is pH?</h3>

The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.

The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.

⇒pH = -log(a_{H+})

Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.
