Solid iron(III) oxide reacts with solid aluminum to produce solid iron and solid aluminum oxide. If 50.0 grams of iron(III) oxide were mixed with 50.0 grams of aluminum, what maximum mass of iron metal could be produced?
find out the ΔH rxn for the given reaction as C 3 H 4 (g) + 2 H 2 (g) → C 3 H 8 (g)
What is a sigma bond? What is a pi bond? Must a double bond have a sigma bond and a pi bond?
A sample of N2 (g) occupies a volume of 42.0 mL under the existing barometric pressure. Increasing the pressure by 85 mmHg reduces the volume to 37.7 mL. What is the prevailing barometric pressure in mmHg
spontaneous chemical reactions produce products which are more energetically stable than the reactants which form them. A strong acid reacts with a strong base to produce water and the free ions of a salt.
A student in the laboratory connects a 10-Ω resistor, a 15-Ω resistor, and a 20-Ω resistor in series and then connects the arrangement to a 50-V dc source.
