2KClO₃ → 2KCl + 3O₂
mole ratio of KClO₃ to O₂ is 2 : 3
∴ if moles of O₂ = 5 mol
then moles of KClO₃ =
= 3.33 mol
Mass of KClO₃ needed = mol of KClO₃ × molar mass of KClO₃
= 3.33 mol × ((39 × 1) + (35.5 × 1) + (16 × 3) g/mol
= 407.93 g
Answer:
= 29.64 g NaNO3
Explanation:
Molarity is given by the formula;
Molarity = Moles/Volume in liters
Therefore;
Number of moles = Molarity × Volume in liters
= 1.55 M × 0.225 L
= 0.34875 moles NaNO3
Thus; 0.34875 moles of NaNO3 is needed equivalent to;
= 0.34875 moles × 84.99 g/mol
= 29.64 g
Answer: 5.72 g mass of carbon dioxide was produced
Explanation:
Moles of C =
Mass of 
reacted = 59.1 g - 17.5 g = 41.6 g
Moles of 
According to reaction 1 mole produces 1 mole of 
then 1.3 mole of will produce 
moles of
Mass of :
=Moles of × molar mass of = 1.3 ×44 g/mol =
=57.2 grams
5.72 g mass of carbon dioxide was produced
Answer:
Hey
It should be Atomic theory,
First proposed in the 15th centery by Aristotle, it states that all matter is made of <em><u>induvisable particles called atoms...</u></em>
