The diagram shows four different locations in an atom. A shaded circle is shown, labeled nucleus. Two small points labeled two and three are shown inside this shaded circle. A lighter shaded concentric circle is shown with a radius more than double the radius of the inner circle. A point labeled one is shown inside a section of this circle which does not overlap with the inner circle. A flower petal like shaded region is shown above and below these circles. A point labeled four is shown inside the lower petal.

here are the traits of a good leader.i'm not going to give you the examples so you can copy right it.that's illegal but i hope that this you out.

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
