Answer:
Explanation:
C2H4 + O2 → CO2 + H2O
eqn is unbalanced - balancing by counting no. of C n H atoms
C=2 n H=4 in one C2H4
so the reaction will form two CO2 + two H2O
counting no. of O atoms: 2*2 + 2*1
=4+2
C, because a half-life is the amount of time it takes for half the atoms to decay.

Answer:
178.98 sq. feet
Explanation:
The path and the garden has been shown in the figure below. The green area is the garden and the area in brown is the path.
It has been given that,
Radius of garden = 8 feet
So, the area of garden = 3.14 × 8 × 8 = 200.96 sq. feet
The total radius of the land including garden and path = 8 + 3 = 11 feet
So, the total are of land including garden and path = 3.14 × 11 × 11 = 379.94 sq. feet
So, the area of path = Total area of the land - area of garden
Area of path = 379.94 - 200.96 = 178.98 sq. feet
