The root mean square speed of co at 113 c is m/s

Your answer is he rms speed is 586 m/s. The equation for rms speed is rms_speed = sqrt((3*gas constant*temperature_in_Kelvin)/molar mass). The gas constant is 8.31 kgm^2/(s^2Kmol) and molar mass is 0.028Kg/mol. Convert Celsius to Kelvin => 386K and plug in the numbers. Rms_speed = sqrt((3*8.31*386)/0.028) = 586m/s.

Explanation:

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

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
