how do you make carbon disulfide?
373702
In nature, small amounts of carbon disulfide are found in gases released to Earth's surface as, for example, in volcanic eruptions or over marshes. Commercial carbon disulfide is made by combining carbon and sulfur at very high temperatures.

CH3CH2C(CH3)3.\nI guess you forgot to type the C before the parenthesis. If you didn't forget, then none of the answers is correct (you would be missing a carbon atom).\n\nChem-man I would have contacted you in private about this but you do not give us the option to e-mail you. I have seen several of your answers prompting askers to verify your answer through echemistryhelp. I checked the website and it is not a free one; you post a question and pay for the answer. I'd say that this is a form of indirect advertisement  which is against the community guidelines. Please refrain from doing that or I will have to report you.

Just how much Hydrogen do you want to produce?\nI could tell you several ways to make small amounts for next to no cost, but if you want to step up production, it will involve increase the price too.\n\nElectrolysis of water is probably the cheapest method, especially when the energy your using is cheap/free too.  The cheaper the energy, the cheaper the over all price.  The energy from a battery is much more expensive than the energy "out of the wall" which is much more expensive than energy from the sun (free).\n\nYou could also produce Hydrogen by reacting a more active metal in an acid.  Metals like Iron, Zinc, Magnesium, (you could use the Alkili metals, but I woulnt advise it), ...\nCopper (in a penny) wouldnt work since it is less active than Hydrogen, but the zinc inside the penny would. [we ignore the cost of the penny you have to destroy]

you mean into a chloride?\neasy just add concentrated hydrochloric acid.the chloride will precipitate. and the sulfate will come out as hydrogen sulfide gas and water. maybe you need hydrogen to be passed in the mixture.\nna 2(so4)   + hcl  =      nacl   + h2s  + h2o

Carbon at room temperature and pressure is a solid, not a gas. If you raised its temperature enough to make it a gas, it would become highly reactive and would be too hot for you to breathe.

Carbon is a remarkable element for many reasons. Its different forms include one of the softest (graphite) and one of the hardest (diamond) substances known. Moreover, it has a great affinity for bonding with other small atoms, including other carbon atoms, and its small size makes it capable of forming multiple bonds. Because of these properties, carbon is known to form nearly ten million different compounds, the large majority of all chemical compounds. Carbon compounds form the basis of all life on Earth and the carbon-nitrogen cycle provides some of the energy produced by the sun and other stars. Moreover, carbon has the highest melting/sublimation point of all elements. At atmospheric pressure it has no actual melting point as its triple point is at 10 MPa (100 bar) so it sublimates above 4000 K. Thus it remains solid at higher temperatures than the highest melting point metals like tungsten or rhenium, regardless of its allotropic form.\n\nCarbon was not created in the Big Bang due to the fact that it needs a triple collision of alpha particles (helium nuclei) to be produced. The universe initially expanded and cooled too fast for that to be possible. It is produced, however, in the interior of stars in the horizontal branch, where stars transform a helium core into carbon by means of the triple-alpha process. It was also created in a multi atomic state

1. Diamonds and graphite are a form of carbon.\n\n2. Ammonia is made using the Haber process.\n\nLook here for details\nhttp://www.ausetute.com.au/haberpro.html\n\nIt is used as a fertilizer, explosives, chemicals\n\n3. Ozone in the upper atmosphere act as a filter for UV rays, which are harmful to life.\n\n4. Halogens have an outer orbital that will be filled if they add one electron\n\n5. Noble gases have an outer orbital that is completelly filled.

The site pointed to above does a good job explaining the mechanism. Just remember that with any unimolecular reaction, there must be a rate determining step.  Since it is always harder to form a carbocation, the ionization step will be your rate determinant.\n\nA few other pointers on carbocation formation:\n\nYou want an ionizing solution.  This basically means a polar protic solvent like water will do the job much better than a polar aprotic one like an ether.  Hydrogen-bonds will help stabilize the carbocation intermediate really well so you're much more likely to produce a C+ in H-bonding solutions.\n\nYou will also form the most substituted product.  So look at all the elimination possibilities and pick the one that's got the fewest H's on your SP2 Carbons.  And anytime a carbocation is involved, you gotta watch out for skeletal rearrangement.

It can be made by dehydration of acrylamide\nCH2=CH-C(O)NH2 --> CH2=CH-CN + H2O\nP2O5 is a good reagent for that.

Disulfide bonds form by the reduction of two thiol groups of Cysteine residues of polypetides or amino acids. The R group of Cysteine is -CH2SH.\nWhen oxidized two cysteine looses a Hydrogen atom each. \n\nR-SH + R-SH --> RSSR + 2[H]\n\nThe bond -S-S- is known as Disulfide bond.

First you need to balance the equation.  In order to do this, there must be the same number of each atom  on both sides.\n\nFeO(s) + C(s) --> Fe(l) + CO2(g)\n\nBalanced, the equation looks like this:\n\n2FeO + C -> 2FE + CO2\n\nNotice how there are the same number of each type of atom on both sides of the equation?  In order to make CO2, you have to have 2FeO because each FeO molecule has only one oxygen atom to provide for CO2.  This leaves 2 Fe left over after those oxygens are popped off and put on the carbon molecule.\n\nWhat the equation means is that for every 2 of FeO you have, you need 1 carbon in order to convert it into CO2 and you get 2 Fe ions left over from the reaction.\n\nIf you start out with .135 moles of FeO, you need 1/2 that amount in carbon for the reaction, because for every 2 FeO, you only need 1 carbon for the conversion.  You get the same amount of Fe as you had FeO and half that as CO2.\n\nIn other words:\n\n.135 moles of FeO plus .0675 (this is half of .135) moles of C\n\nwill be converted into:\n\n.135 moles of Fe plus .0675 moles of CO2

The answer is B.\n\nIn your beginning reaction CO2 + C --> CO, you have 2 carbons and 2 oxygens on the reactants side, and you have 1 carbon and 1 oxygen on the products side.\n\nIn order to make the equation balanced, you have to make sure there are the same number of each element on both sides of the equation.\n\nSo to make this chemical equation balanced all you have to do is put 2 as the coefficient of the CO on the products side, making the final equation:  CO2 + C --> 2CO\nThis will give you 2 carbons and 2 oxygens on both sides.
