AP Chemistry basic reaction problem

AI Thread Summary
Mixing cobalt(II) nitrate with sodium hydroxide results in a neutralization reaction, producing sodium nitrate and precipitating cobalt hydroxide. The solubility rules indicate that most hydroxides are insoluble, with exceptions for alkali metals and some alkaline earth metals. Cobalt hydroxide may also undergo thermal decomposition into cobalt oxide and water due to the exothermic nature of the reaction. Understanding these concepts is crucial for solving similar problems in AP Chemistry. Mastery of solubility rules and reaction types is essential for success in the course.

Homework Statement



Solutions of cobalt(II) nitrate and sodium hydroxide are mixed.
What are the solubility rules for the hydroxides?

and it occurs in a aqueous solution

Homework Equations



I have no idea how to solve these problems from my chem class lasty year and we will be getting a problem similar to this tommorow (first day AP Chem class) and I was woundering if anyone could walk me through the steps you need to know to solve this and the answer.

The Attempt at a Solution

 
Physics news on Phys.org
Cobalt (II) Nitrate is acidic, and Sodium Hydroxide is an alkali, so they will undergo neutralization reaction. Sodium Nitrate will form and Cobalt Hydroxide will precipitate. It is possible that some Cobalt Hydroxide can undergo thermal decomposition into Cobalt oxide and water due to exothermic neutralization reaction.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
