Would you expect hexane to be soluble in water?
The density of cyclohexane is lower than that of water (0.779 g/mL vs. 1.0 g/mL respectively), so it will float on top of water.
What is a formula for sodium hydrogen sulfide?
The formula for dihydrogen sulfide, or just hydrogen sulfide, is H2S. A pair of hydrogen atoms are bonded to a sulfur atom to make up this toxic compound. A link can be found below for more information.
What mass of oxygen (O2) is required to react completely with 86.17 grams of C6H14?
The answer is 152 g oxygen.
What is the molecular mass of hydrogen sulphide H2S?
34.08 g mol-1
How can you calculate the amount of carbon dioxide emitted from the burning of an object?
This can be done precisely under certain conditions, but in practice things aren't so simple. You need to know the exact chemical formula of the thing being burned (this can be difficult if you are burning wood, for instance, which is a complex mixture of thousands of compounds). You also have to assume that the combustion is complete -- in other words that all hydrocarbons are completely converted into carbon dioxide and water, which is not always the case in normal burning situations. The actual reactions that occur while burning something are very complicated in fact, but to a close approximation, you can figure out the amount of CO2 produced in the following way:First, write the balance equation for the combustion of the hydrocarbon. The reactants are the hydrocarbon itself and oxygen gas (O2). The products are carbon dioxide and water. See the Related Questions to the left for how to do this.Then use stoichiometry to figure out for a certain amount of hydrocarbon burned how much CO2 you will produce. See the Related Questions links to the left for how to do this also.See the Related Questions links to the left for detailed instructions on how to do each of these steps! Note that in both of the related questions, example problems have been worked out using the combustion of a hydrocarbon! Most of the work is done for you already! Just see the examples in the linked questions to the left.
Does sulphur dissolve in hexane?
SOLUBILITY IN WATER Insoluble SOLVENT SOLUBILITY Soluble in hexane, toluene, ethanol and acetone. Insoluble in propylene glycol --- The above statement with water is wrong. I am currently running experiments on equilibrium concentration of succinic acid in a water/hexane system. I was able to find several articles in the litterature where a mixture of succinic acid and n-butanol is used, but nothing with succinic acid and hexane. I estimate the solubility of Succinic Acid in water to be ≥23.020±0.005 g/kg of water @ 21˚C. So far, 0.1g do NOT disolved completely in 133g of hexane, even after being heated to about 35˚C and stirred intensively for several hours. CHG Patrick - 25/08/10 ---- Patrick is absolutely right. The first answer is completely wrong. Succinic Acid is not going to be soluble in hexane as Malonic and Succinic acid are both highly polar substances and Hexane is Non-Polar. Like dissolves like. -Trifectaus Sept 7,2010
How many moles of hydrogen sulfide are contained in a 64.6-g sample of this gas?
H2S 63.1 g H2S * 1 mol H2S / 34.076 g H2S = 1.85 mol H2S
What is the denisty of hexane?
The Density of Hexane is 0.6548 g/ml.

Is C6H14 an organic or inorganic compound?
Yes, it is the organic compound hexane or one of its isomers.
Is hydrogen sulfide soluble?
Yes, hydrogen sulfide (H2S) has some solubility in water depending on temperature.The solubility of H2s in water is approximately:0.4 g H2S /100 mL solution (20 °C)0.25 g H2S/100 mL solution (40 °C)More detailed data is provided in the links below.

What is the molecular mass of hexane?
86.18 g/mole
What is the density of hexane?
86.18 g/mol, from Wikipedia http://en.wikipedia.org/wiki/Hexane Btw, The molecular molecular weight of a compound is the same thing as molar mass. Wikipedia has molecular weight for almost every compound in the bar/table on the right side of the webpage for the compound, next the label "molar mass". 86.18 g/mol, from Wikipedia http://en.wikipedia.org/wiki/Hexane Btw, The molecular molecular weight of a compound is the same thing as molar mass.
