Learn chemical reaction equations?

Click For Summary

Discussion Overview

The discussion revolves around learning chemical reaction equations, specifically focusing on balancing equations and predicting products of reactions. Participants share their experiences and challenges in understanding these concepts, as well as resources for further learning.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant expresses a desire to learn reaction equations but faces challenges due to a lack of formal education and prefers personalized guidance.
  • Another participant questions whether the learner wants to focus on balancing equations or predicting products, noting that predicting products requires extensive knowledge of compound properties.
  • A participant emphasizes that writing reaction equations necessitates knowing the formulas of reactants and products, and that predicting products is integral to learning chemistry.
  • There is a suggestion to practice with specific reactions, such as the reaction between HCl and NaOH, to help understand the concepts better.
  • A later reply critiques a previous explanation as convoluted but acknowledges that the final answer regarding the products of acid-base reactions is correct.
  • One participant provides a link to additional resources for learning and expresses willingness to assist once the learner begins studying independently.

Areas of Agreement / Disagreement

Participants generally agree on the importance of understanding the principles behind chemical reactions, but there is no consensus on the best approach to learning or the accuracy of specific explanations provided.

Contextual Notes

Some participants note the complexity of predicting products and the necessity of prior knowledge, indicating that the discussion may be limited by the learner's current understanding of chemistry.

In order to understand some areas of chemistry I have gotten interested in, I believe it in my best interest to learn reaction equations. Like every other reality situation, there are problems. For one, my school doesn't have the ability to teach me this, secondly, online ones for me are harder to grasp, I prefer one-one-one. While I am not asking someone to waste their time on me, I am asking some people to provide links to sites they find suitable for me (in other words, not useless).

What do you mean? Do you want to learn how to balance them? Thats relatively easy. Or how to predict products? There is no sure method, you need to learn a lot about properties of compounds and even then you will be surprised be the reality.

Lets say we have two elements, I know how they react (moderately) but don't know how to write the equation of how they react, and yes predict products of reactions and why those products are the ones made
 
To write reaction equation you have to know formulas of reactants and products. As I wrote earlier, predicting products requires a lot of knowledge, in a way that's what the chemistry is all about, so in fact all the time you learn chemistry, you learn how to predict products.

Earlier you were trying to learn something about acids and bases, I proposed you to try to predict products and balance reaction equation for HCl and NaOH. Try again, you were already partially right then. That will help you predict products of most simple reactions between acids and bases, that's whole class of reactions, one of the steps on the ladder up.

What I think will happen in a reaction between HCI and NaOH is the hyrodgen ions in each of the compoundswill 'break up' because they are in a aqueous soultion, so they will form a ionic bond between each other, neutralizing each others charge. The two hydrogen atoms will then react with oxygen and form a covalent bond, making H20, the chlorine (is it an ion, if so why?) will react with the sodium and form sodium chloride, or basically, table salt. Good enough?
 
Convoluted and mostly wrong in the middle, but the final answer is right - when acids react with bases, products are salts and water.

When base dissociates it gives off OH- which reacts with H+ from acid dissociation, so neutralization reaction is basically

OH- + H+ = H2O

But don't count on more similar lessons on every kind of possible reactions from me or anyone else here. That was just an example. Now go here:

and try to learn from the resources presented there. We will be more than happy to help you understand the material once you will start learning on your own.
