Answer:
0.0002 M
Explanation:
<em>The molarity of the HCl required would be 0.0002 M.</em>
First, let us consider the balanced equation of the reaction:

<em>Stoichiometrically, 1 mole of </em>
<em> reacts with 2 moles of </em>
<em> for a complete neutralization reaction.</em>
Recall that: mole = 
Mole of 0.550 g sodium oxalate = 0.550/134 = 0.0041 mole
<em>If 1 mole </em>
<em> requires 2 moles HCl, then 0.0041 mole will require</em>:
0.0041 x 2 = 0.0082 mole HCl
Volume of the HCl = 40.95 L
Molarity = mole/volume
Hence, molarity of the HCl = 0.0082/40.95 = 0.0002 M
The hammered bananas will undergo a physical change when hammered, and both a physical and chemical change when put into liquid nitrogen. The will freeze and harden, causing them to be solidified once again, yet their temperature will lower exponentially, causing them to freeze. Physical change is when it hardens and the temperature drops. chemical when it freezes.
