Becuase they have water and oxygen carbon dioxide in them
Answer:1.30 x 10 to the 4th
Explanation:
Just know
<span> It is important to keep the NaOH solution covered at all time because sodium hydroxide is a very good remover of Carbon dioxide from the air means sodium hydroxide absorbs the carbon dioxide from the air react with that so the concentration of your solution will also change if you uncover the NaOH.
The following reaction occurs when sodium hydroxide reacts with carbon dioxide;
</span><span>2 NaOH(aq) + CO2(g) --> Na3CO3(aq) + H2O(l) </span>
Answer:
The answer is "
"
Explanation:
The water solution of PbCl2 is poor. It also has 2 distinct dissolving properties. In cold water, this will not dissolve easily.It is water-insufficiently soluble. And that in cold water, it is indeed insoluble. That's why we know that all energy should be available for a solid to dissolve in the liquid to counteract that attractive force between the ions in the grid.
Answer:
MgCl2 - 6H2O
203.3 mol
MgCl2 + 2Na = 2NaCl + Mg
22.6g
Explanation:
1. Write the formula of hydrate and find molar mass.
2. Write a balanced single replacement (don't include H2O)
3. Do the given/wanted calculation (include H2O in molar mass of given)
