Answer : The total mass of oxygen gas released in the reaction will be, 12.8 grams
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,

According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of  = Total mass of
 = Total mass of 
or,
Total mass of  = Mass of
 = Mass of  + Mass of
  + Mass of 
As we are given :
Total mass of  = 16.12 grams
 = 16.12 grams
The mass of  = 9.72 grams
 = 9.72 grams
So,
Total mass of  = Mass of
 = Mass of  + Mass of
  + Mass of 


Therefore, the total mass of oxygen gas released in the reaction will be, 12.8 grams
 
        
             
        
        
        
The correct answer is<span> C) Water takes long to heat and cool down than other liquids.
It doesn't climb up the sides of a tube any more than other solutions do, and being a universal solvent has nothing to do with radiators. It does however take a long time to heat and cool down since you don't have a 100+ celsius burner to heat it up in an instant.</span>

Given what we know, we can confirm that option A is correct in that Stronger IMFs lead to stronger adhesion, producing rounder drops with a smaller diameter.
<h3>What are IMFs?</h3>
IMF is the acronym used to describe intermolecular forces. These forces include all of the forces that bind molecules together, of which water has plenty. This bonding force creates a high adhesion and thus gives water its surface tension which makes it stay together in the shape of a drop.
Therefore, we can confirm that stronger IMFs lead to stronger adhesion, producing rounder drops with a smaller diameter, and therefore that option A is correct.
