Asettling tank is to precipitate (m) high. the density of the solid is 2500 kg/m3; the horizontal velocity of the input suspension is 0,015 (m/s). supposing the viscosity of the suspension is the viscosity of water at the ambient temperature, the settling process is working at stokes-laminar hydraulic mode. dispersed solid particles in water. the tank is 40 (m) long and 8 est particles that settle in the tank? ) b) if the smallest particle is 30 (um) in diameter, what is the length of the tank ?

i don,t know so just answer mine

the maximum mass of nh3 is nh3 in grams

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
