The oxidation of aluminium is a pretty common reaction, and happens via the equation below.
4Al + 3O2 → 2Al2O3.
Which reactant is limiting if you begin with 9.50 grams of Al and 9.50 grams of O2?
Problem- A 50.00-g sample of metal at 78.0 degrees C is dropped into cold water.If the metal sample cools to 17.0 degrees C and the specific heat of the metalis 0.108 cal/g. degrees C, how much heat is released
What is the identity of the precipitate that forms when 45 mL of 0.3 M HCl reacts with 40 mL of 0.35 M AgNO3?
When 4.00g of hydrogen nuclei fuse to form helium in the sun, 0.0265g of matter is converted into energy. Given that the speed of light = 3.00x10^8 m/s and that a jolue = kg*m^2/s^2, calculate how much energy is given off.
My gas tank in my car has a total volume of 68 L. The manual says the gas gauge light will come on when there are only 5 L remaining in the tank and that the car will not be able to draw on the last 2 L in the tank.
