Four balloons of equal size are each filled with a gas under one of the following conditions: A) Hydrogen gas at room temperature, B) Hydrogen gas.. at 0 deg. C, C) Clean air at room temperature, D) Clean air at 0 deg. C. Which of these balloons will shrink the fastest? Please give an explanation with the answer.

i don,t know so just answer mine

i'm wiling to try and you : )

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

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
