The mass of Al metal that releases 2.4 L of hydrogen gas at STP is calculated as below
AT STP 1 mole =22.4 l
what about 22.4l =? moles
(22.4 L x 1 mole) /22.4 L= 2mole
write the reacing reaction
2Al+ 6 HCL = 2AlCl3 + 3H2
by use of mole ratio between Al to H2 which is 2 : 3 the mole Al = 1 x2/3 = 0.667 moles
mass =moles x molar mass
=0.667 mole x27 g/mol= 18 grams
embedded in the inner membrane are proteins and complexes of molecules that are involved in the process called electron transport. The electron transport system (ETS) as it is called, accepts energy from carriers in the maxtrix and stores it to a form that can be used to phosphorylate ADP. Hope this helps!
<span>With new results, new questions will appear. Science is always changing, or rather how we perceive conclusions to questions we have can be wrong. </span>
Earlier species thanks to evolution. hope this helped!
