Answer:
m(O₂) = 3.666 g
Explanation:
The rusting of iron is due to its reaction with oxygen. The balanced equation is:
4 Fe + 3 O₂ → 2 Fe₂O₃
According to Lavoisier's law of conservation of mass, the sum of the masses of the reactants is equal to the sum of the masses of the products.
m(reactants) = m(products)
m(Fe) + m(O₂) = m(Fe₂O₃)
8.531 g + m(O₂) = 12.197 g
m(O₂) = 3.666 g

Answer:
Explanation:
Sound travels outwards from the source in all directions. So there you have it sound does travel faster in warm air BUT it may appear to travel farther in cold air. This is how that works……if the air close to the ground is colder than the air above it then sound waves travelling upwards will be bent downwards.
