Explanation:
A single-replacement reaction replaces one element for another in a compound.
A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.
A precipitation reaction is a double-replacement reaction in which one product is a solid precipitate.
Solubility rules are used to predict whether some double-replacement reactions will occur.
I believe that the molar mass is 342.34g/mol
Answer:
The answer is 2.03
Explanation:
The pH of a solution can be found by using the formula
![pH = - log [ {H}^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20%7BH%7D%5E%7B%2B%7D%20%5D)
where H+ is the Hydrogen ion concentration
From the question we have
We have the final answer as
<h3>2.03 </h3>
Hope this helps you
Answer:
This would be the hydride ion where H gains an electron from a metal such as Na
