Identify the type of bonding molecular geometry and intermolecular forced experienced by the compounds hf and hbr which substanc

e would experience a stronger attraction between its molecules and why
Chemistry

Serhud [2]3 years ago

Both HF and HBr experience H-bond, dipole, and dispersion forces. These forces allow the compounds to have stronger bonds with each other. HF would experience a higher amount of attraction between its molecules. This is because fluorine is more electronegative than bromine.

Hope this helps!

In the reaction of chlorine with calcium, explain which atom is oxidized.
romanna [79]

Answer:

The atom is oxidized is Ca.

Explanation:

  • The oxidation-reduction reaction contains a reductant and an oxidant (oxidizing agent).
  • The oxidation process is the process in which electrons are lost and produce positively charged ions.
  • The reduction process is the process in which electrons is gained and negatively charge ions are produced.

  • In the reaction of chlorine with calcium:

<em>Ca + Cl₂ → CaCl₂,</em>

Ca loses 2 electrons and is oxidized to Ca²⁺. (Ca <em>→</em> Ca²⁺ + 2e).

Cl is gains 2 electrons in "Cl₂, oxidation state zero" and is reduced to Cl⁻. (Cl₂ + 2e <em>→</em> 2Cl⁻).

An isotope of yttrium has 39 protons and 59 neutrons. what is the atomic mass of that isotope?
Charra [1.4K]
We can define atomic mass the total of number of protons and number of neutrons in an atom or isotope.
<span>So when an isotope of yttrium has 39 protons and 59 neutrons, its atomic mass is equal to;
number of protons + number of neutrons = 39 + 59 = 98</span>

Please balance the equation, putting the correct coefficient in each box.
Mariulka [41]

Answer: Bi(OH)_3+3HNO_3\rightarrow 3H_2O+Bi(NO_3)_3

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced equation will be:

Bi(OH)_3+3HNO_3\rightarrow 3H_2O+Bi(NO_3)_3
