Aluminum metal reacts with dilute hydrochloric acid, HCl to form hydrogen gas and a solution of Aluminum chloride, AlCl(Subscript)3What volume of hydrogen at 1.5 atm and 25 degrees celsius will be produced when 35 grams of aluminum reacts with HCl-Provide balanced equations-Show all steps neccesary to determine volume of hydrogenFYI- Any answer is a good answer
Pure aluminium only has a yield strength of around 10 MPa but aluminium-titanium alloys can have strength up to around 600MPaBTW titanium is about 2 times heavier than aluminium which is 2.7grams/cm^3
True aircraft grade aluminum is individually graded based on not composition but on an inspection to make sure there are no irregularities that would cause an unexpected early failure.
I think pure aluminum will have more weight than a credit card for same sizeIt can be aluminum which alloyed by some lighter impurities metalsTotal density of the alloy has lighter weihgt than plastic but has more strength.
Weigh the cardA density of .10 lbs/cu.in would be aluminum, .28 lbs/cu.inwould be carbon steel and .30 would be stainless steelThe gold color is probably a titanium-nitrite coating which provides a wear resistant surfaceIt could of course be an entirely different alloy that density alone would not identify, but this should get you in the proper ballpark, so to speak.
We start with the balanced equation: 2Al (s) + 6 HCl (aq) - 2AlCl(Subscript)3 (aq) + 3 H(Subscript)2 (g) The molar mass of Al is 26.98 g/molDividing the mass given by the molar mass gives the moles of Al: 35g / 26.98 g/ mol 1.3 mol Al (two sig fig) For every two moles of Al, three moles of H2 (g) is produced: 1.3 mol Al (3 mol H2/ 2 mol Al) 2.0 mole H2 gas (the actual answer is 1.95 but rounded to two sig fig, the answer is 2.0; I don't know how strict your teacher is about sig fig) Next rewrite the ideal gas law to solve for volume: V [ nRT ] / P Convert 25 degrees C to Kelvin : 25 + 273 298K R .0821 L - atm/ mol-K P 1.5 atm n 2.0 or if you want you can use 1.95, either way you'll learn how to do the problem V [ 2.0 .0821 298] /1.5 33L If you use 1.95 you'll get 32L
