3NaBr + H3Po4 = Na3Po4 + 3HBr
that is the balanced equation and the reaction type is double replacement
Answer:
4°
Explanation:
Given,
chord in the airstream, c = 2 m
speed, v = 50 m/s
lift per unit span = 1353 N/m
density of air, ρ = 1.225 kg/m³
Lift,



From the plot of c_L and angle of attack
Angle of attack is equal to 4°
