9g Al x (1 mol Al/27g Al) x (3mol H2 / 2 mol Al) x (22.4L / 1 mol H2) = 11.2L H2

How does hydrochloric acid and alluminium react?
Hydrogen gas evolves off the reaction with the formation of a salt, Aluminum Chloride.EXPLANATION:Aluminium reacts with hydrochloric acid to produce hydrogen gas and aluminum chloride. If a sample of aluminum is taken in a test tube with some drops of hydrochloric acid, it burns with a 'pop' sound if a burning matchstick is brought near the test tube, indicating the presence of hydrogen gas.The following reaction takes place(balanced equation):2Al(Aluminium)+6HCl(Hydrochloric acid)----->2Al3HCl(Aluminium Chloride)+3H2(Hydrogen)
How hydrogen detected in the carbon and hydrogen test?
To test for hydrogen in the given substance, a dry sample is needed. Burn it in excess of oxygen. If the vapour turns white copper sulfate into blue colour, it indicates that there is water in present in the vapour. Hence, the organic compound contains hydrogen.
Does hydrochloric acid affect diamond?
No. There are other ways of analyzing a sample to determine whether or not it is diamond, which does not dissolve in hydrochloric acid.
What is the balanced equation of a sample of zinc metal reacting completely with hydrochloric acid?
Zn + 2HCl → ZnCl2 + H2
A scientist measures the temperature of a sample of hydrochloric acid to be 85 celsius what is its temperature in kelvin?
85 + 273 = 358 K.

What Metals are in aluminum?
Aluminum is a pure substance. It is the thirteenth element in the periodic table. Aluminum is the only metal in a sample of aluminum, unless it contains impurities.
How can you eliminate a hydrogen sulfide odor in the water from a new hot water heater even after the anode has been replaced with an aluminum one?
You need to replace the aluminum anode with a zinc/aluminum alloy anode.ANS 2 - If a hydrogen sulfide (or rotten egg) odour exists around your water, it's often an indicator of excess iron in the water supply. This can be bad for your plumbing. I would advise taking a water sample(in a sterilised bottle) to a lab and have it analysed. If the iron content is very high you may well have to fit a softener or an iron filter.BTW - changing the anode is an excellent idea anyway. Just may not be the solution.
What is a sample sale?
A sample sale is when a designer or store sells excess merchandise at a deep discount.
What is the principle behind the shinoda test for flavonoids?
In the Shinoda test for flavonoids, a sample is added to pieces of magnesium and then hydrochloric acid is dripped on the sample. The color the sample turns indicates if there are flavonoids present or not.
