90 points + Brainliest! - I need a thorough response to this assignment. Please do not answer without a correct well written explanation! Thank you! :) Part 1 - If the starting volume of a hot air balloon is 55,500 m^3 and the initial
temperature is 21 °C, what is the temperature inside the balloon is the final
volume is 74,000 m^3?

Part 2 - Explain why the volume of the balloon increases when temperature is increased in terms of average kinetic energy, collisions and volume. Explain how the balloon is actually able to lift off the ground in terms of density. (Density of hot air is 0.946 kg/m^3 and the density of normal ambient air is 1.2 kg/m^3.)

a. hope i'm right

explanation:

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
