Concept explainers

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Souring of wine occurs when ethanol is converted to acetic acid by oxygen: C2H5OH(l) +O2(g)--->CH3COOH(g)+H2O(l). A 1.00 L bottle of wine labeled as 7.00% (%v/v) ethanol, is found to have a defective seal. Analysis of 1.00 mL showed that there were 0.0274 g acetic acid in that 1.00 mL. The density of ethanol is 0.816 g/mL. (a) What mass of oxygen must leaked into the bottle in pounds(lb) (b) What is the percent yield for the conversion of ethanol to acetic acid, if oxygen is in excess
The combustion of liquid ethanol (C2H5OH)(C2H5OH) produces carbon dioxide and water. After 4.63 mLmL of ethanol (density=0.789g/ml)(density=0.789g/ml) was allowed to burn in the presence of 15.50 gg of oxygen gas, 3.70 mLmL of water (density=1.00g/ml)(density=1.00g/ml) was collected.

The reaction of solid calcium fluoride and sulfuric acid produces calcium sulfate solids and gaseous HF. The gas product is dissolved in water to form hydrofluoric acid. Fluorite ore, a source of calcium fluoride, contains 95%wt CaF2 and 5%wt SiO2. In a certain process, the ore is reacted with 93%wt aqueous sulfuric acid, supplied 15% in excess. From this, 95% of the ore dissolves in the acid. Some of the HF formed reacts with the dissolved silica in the reaction: HF reacts with SiO2 to produce H2SiF6 and liquid water. If 60%wt of hydrofluoric acid was formed when hydrogen fluoride (which exits the reactor) is dissolved in water, determine the amount of ore needed to produce one metric ton of acid. Report your answers to one decimal place only.
For divers going to great depths, the composition of the air in the tank must be modified. The ideal composition is to have approximately the same number of O2 molecules per unit volume as in surface air (to avoid oxygen poisoning), and to use helium instead of nitrogen for the remainder of the gas (to avoid nitrogen narcosis, which results from nitrogen dissolving in the bloodstream). Of the molecules in dry surface air, 78.0% are N2, 21.0% are O2, and 1.00% are Ar. (Assume that the density of seawater is 1025 kg/m3 and the temperature is 20.0°C.) Density of dry air at 20.0°C is 1.20 kg/m3. Molar mass of N2 is 14.007 g/mol, O2 is 15.999 g/mol, and Ar is 39.948 g/mol. a: How many O2 molecules per cubic meter are there in surface air at 20.0°C and 1.00 atm? b: For a diver going to a depth of 141 m, what percentage of the gas molecules in the tank should be O2?
Heating MgSO4•7H2O at 150oC produces a different hydrate, MgSO4•XH2O. If heating 24.4 g of pure MgSO4•7H2O at 150oC were to give 17.2673 of pure MgSO4•XH2O, what is the integer value for X?
1. One of the first families of rockets used by the American space program was the Redstonefamily of rockets. The first Redstone rockets (in the 1950s) used B10H14 (often called decaborane)as a rocket fuel that reacts violently with liquid di-oxygen to make diboron trioxide and steam.When used as a rocket fuel, scientists carefully calculated the amount necessary so that bothcomponents ran out at the same time. (Excess fuel would be excess weight for the rocket tocarry.) If the total mass of both reactants put together is 12.0  104 kg, what was the volume ofliquid di-oxygen carried by the rockets? (Liquid di-oxygen has a density of 1.141 g/mL.)

A hydrate [hydrates have the general formula AB • xH2O] is found to have the percentcomposition: Na = 19.17%, C = 10.00%, H = 4.17% and O = 66.6%. After heating to 100 oC todrive off the water of hydration, the percent composition is found to be: Na = 27.38%,C = 14.28%, H = 1.19% and O = 57.15%. From this data, determine the probable molecularformula for the hydrate if the molecular weight = 120 amu.
