Sushil Kumar answered • 2 hours agoChemical fertilisers are being used in increasing amounts to increase output in high yielding varieties of crop plants. However, chemical fertilisers cause pollution of water bodies as well as groundwater, besides getting stored in crop plants. They are expensive and also require a lot of energy resources in their manufacture.

Mohit Rajpoot answered • 2 hours agoHere m = 5kg
∴ uy = 40 m s-1 and Fy = -5 N
= 1 m s-1 vy = 0
As vy = uy + ayt or 0 = 40-1 x t
∴ t = 40s
∴ uy = 40 m s-1 and Fy = -5 N = 1 m s-1 vy = 0
As vy = uy + ayt or 0 = 40-1 x t
∴ t = 40s

Mg is a limiting reagent and is in excess by 0.5 g
c)
O2 is a limiting reagent and is in excess by 0.25 g

Diwakar Singh answered • 2 hours ago
48 g of Mg requires 32 g of O2
1 g of Mg requires 32/48 = 0.66 g of O2
Oxygen available = 0.5 g
Hence, O2 is limiting reagent.
32 g of O2 reacts with 48 g of Mg
0.5 g of O2 will react with 48/32 x 0.5 = 0.75 g of Mg
Excess of Mg = (1.0 - 0.75) = 0.25 g
