What’s the balanced equation for the reaction between zinc oxide and dilute hydrochloric acid ?
larisa [96]

Answer:

ZnO + 2HCl → ZnCl₂ + H₂O

Explanation:

The <em>unbalanced reaction</em> between zinc oxide (ZnO) and dilute hydrochloric acid (HCl) is:

  • ZnO + HCl → ZnCl₂ + H₂O

Now we'll procede to <u>balance the equation</u>:

  • <em>There is 1 Cl atom on the left side and 2 on the right</em>, so we change that:
  • ZnO + 2HCl → ZnCl₂ + H₂O

The number of atoms for each element is the same on both sides, so the equation is now balanced.

Considering only electron density, will the following reaction occur? <br> 327d1 + 327d2 → yes no
Firlakuza [10]

Answer:

The question is not so clear, but there is a similar question that talks about reaction of alkanes with ammonia

Explanation:

The underlying factor dependent on whether alkane will react with ammonia or not is in their bond and reactivity. basically, alkanes are saturated hydrocarbons with a single bond existing between their chains. They are single bonded hydrocarbons and they majorly undergo SUBSTITUTION REACTION WITH HALOGENS

Alkanes are less reactive in this case, if other functional groups are attached or takes place alongside the reaction, the reaction may have a high chances of taking place.
