Answer:
hope this helps.answer is in the picture
<span>The Law of Conservation of Mass simply states
that the total amount of mass should not change in a chemical reaction that is
isolated (no other objects can enter the reaction). The total mass of the
reactants must be equal to the total mass of the products. Thus, t</span>he correct estimate of
the amount of oxygen used in the interaction is the difference between 133
g and 29 g.
<span>Van der waals interactions are the electrical interactions between two or more atoms and even molecules but the inter-molecular attractions between the molecules are not exactly strong, in fact they are the weakest. And these Van der waals interactions are happened when electrons are not symmetrical distributed in a molecule.</span>
Answer: oxygen=2.547g
Explanation:
Based on the question,it was observed that the reaction is reversible
2 moles of KClO3 gives 2 moles of KCl and three moles of O2
Molar mass for KClO3 is 245 g/mol
Molar mass for O2 is 96 g/mol
We are to find the mass of O2 and we Are given the mass KCLO3 is 6.50g
245g of KClO3 gives 96g of O2
6.50g of KClO3 gives xg of O2
Cross multiply
245x=624
X=624/245
X=2.547g
Therefore the gram of oxygen is 2.547g
