Answer:
Large birds can't fly due to higher weight and weak wings.
Why large birds can't fly?
Large birds like pheasants often walk short distances whereas small birds like chickadees never walk but fly because the large birds have more weight which can't support by the wings to fly in the sky so they walk on the land instead of flying.
While on the other hand, small birds have lower weight and easily fly in the sky so they don't need to walk on the ground so we can conclude that large birds can't fly due to higher weight and weak wings.

Answer:
Explanation:
Hi there!
2Pb (no₃) -------> 2Pb + 4no₂ + o₂
Molecular mass of 4no₂ = 184g
Molecular mass of o₂ = 32g
From the reaction;
When 184 g of no₂ was formed 32 g of oxygen was formed.
When 1 g of no₂ was formed 32/184 g of oxygen was formed.
When 11.5 g of no₂ was formed (32/184)*11.5 g of oxygen was formed.
Therefore, when 11.5 g of no₂ was formed 2 g of oxygen was formed.
Hope it helps!
