Ch3cooh (acetic acid) can form hydrogen bonds between its molecules. based on the lewis structure shown below, how many hydrogen
never [62]
Answer:
           Number of Hydrogen Bond Acceptor atoms  =  2

           Number of Hydrogen Bond Donor atoms  =  1

Explanation:
                   Hydrogen bond interactions are formed between those molecules which contains partial positive hydrogen atoms bonded covalently to most electronegative atoms like Oxygen, Nitrogen and Fluorine. 
                   When hydrogen is attached to Oxygen, Nitrogen or Fluorine its electron density decreases and gets partial positive charge, this partial positive charged hydrogen atom then makes hydrogen bonding with the most electronegative element (partial negative) of neighbor molecule.
                    In Acetic acid there are two oxygen atoms hence there are two most electronegative elements therefore, two Hydrogen Bond Acceptor atom and each oxygen atom can accept two hydrogen bonds.
                    Also, it contains only one Hydrogen atom attached to oxygen atom so it has one Hydrogen Bond Donor atom.

Fe2O3 + 3 Mg --> 2 Fe + 3 MgO reaction type
Bingel [31]

Answer: I'm not sure what answer to give you since there are no answer choices, but here is what I got.

Explanation:

Mg is a reducing agent, Fe 2O 3 is an oxidizing agent.

Igniting a mixture of Fe2O3 and Al with a magnesium ribbon fuse produces molten iron and aluminum oxide in an impressive exothermic reaction.

Hope this helped a little:(

What is the nature of ions formed by different atoms.
lys-0071 [83]

The nature of ions formed by different atoms is as follows:

  • Metal atoms form positively-charged ions
  • Non-metal atoms form negatively-charged ions

<h3>What are ions?</h3>

Ions are substances which are formed when neutral atoms gain or lose electrons.

There are two types of ions based on the charge the ion carries;

  1. anions - which are negatively-charged
  2. cations - which are positively-charged

The nature of the ions formed by different atoms depend on whether the atoms are atoms of metals or atoms of non-metals.

Metal atoms form positively-charged ions by the loss of one or more electrons as illustrated below:

  • M → M⁺ + e⁻

where; M is a metal atom, M⁺ is a metal ion, and e⁻ is an electron.

Non-metal atoms form negatively-charged ions by the gain of one or more electrons as illustrated below:

  • N + e⁻ → N⁻

where; N is a non-metal atom, N⁻ is a non-metal ion, and e⁻ is an electron.

In conclusion, the nature of ions formed by atoms depends on the nature of the atom, whether they are metallic or non-metallic atoms.
