<h3><u>Answer;</u></h3>
HCl dissociates more.
<h3><u>Explanation</u>;</h3>
- HCl is a strong acid while HC2H3O2 is a weak acid. A strong acid such as HCl ionizes or dissociates completely in an aqueous solution by losing one proton.
- A weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution. For example; HC2H3O2.
<span> Na2CO3 + 2HCl = CO2 + H2O + 2NaCl
this is the double displacement reaction
</span><span>2 Na(+) + CO3(-2) + 2H(+) + 2Cl(-) ------> 2Na(+) + 2 Cl(-) + H2O + CO2
</span>2Na+ and 2Cl- are the spectator ions as they appear on the both sides of equation :
so the net ionic equation can be written as :
CO3(-2) + 2H(+) -------------> <span>H2O + CO2</span>
Explanation:
Objects or substances with their density greater than that of water will sink in it whiles those less than water will float on it.
From the question the object has a density of 3.4 g/mL.
Since it's density is greater than that of water the object will sink.
Hope this helps you
