CaO+ H2SO4======> CaSO4 + H2OSo 98 g of H2SO4 neutralises 56 g of CaO.So 49 g of H2SO4 will be neutralised by 0.5 mole or 28 g of CaO.CaCO3 will decompose to CaO as follows.CaCO3 ====∆==> CaO+ H2OSo 100 g of 100% pure will produce 56 g of CaO.Therefore to produce 28 g of CaO we require = 28/56 x 100= 50 g.Since the CaCO3 is only 80% pure, the weight of CaCO3 required = 50/0.8= 62.5 g=÷×=÷×=÷×=÷×=÷×=÷×=÷=÷×=÷×=÷×=÷CaCO3 <===> CaO <===> H2SO4100 <======>56 <=====> 98? <========>? <=====> 49So 50 g <=====> 28 <========> 49So 100% CaCO3 required = 50- gweight of 80% CaCO3 needed= 50/0.8= 62.5 - g=÷×=÷×=÷=÷×=÷×=÷×=÷×=÷×=÷×=÷×=

There’s a problem with your question in that it assumes there is only one form for a visa. There are a myriad of visas available to the US - some immigrant and some non-immigrant - and the forms you file vary for each. The USCIS offers blank versions of all of their forms with instructions on their site. There are also related forms that are not necessarily visa applications, but forms that support an application (like an I-134 which is an affidavit of support) or that are submitted in conjunction with a visa application (like a G-28 that is the official record of notice of appearance for an attorney representing you). If you are applying for a visa abroad at a US Consulate, there are separate forms you would use that can be found on the US State Department website.If there is a specific visa form you are interested in, let me know in a comment and I’ll see if I can point you in the right direction.

Not all farts are created equal - some people fart methane, and others fart a mix of carbon dioxide and hydrogen, What camp you fall into depends on your gut microbiome - the kind of bacteria that live in your gut, where they consume the things that we ourselves can’t absorb - or at least not fast enough.The density of any gas - if the temperature and the pressure are the same for each sample - is directly proportional to the molecular mass of the particles that make up the gas: It’s the old gas equation p•V = N•k•T where N is the number of particles in your gas sample.For methane (CH4) the molecular weight is roughly 16 g/mol. Air is mostly nitrogen with a molecular weight of 28 g/mol. So methane farts are certainly lighter than air.Carbon dioxide / hydrogen farts are trickier. Carbon dioxide has a molecular weight of 44 g/mol and is clearly heavier than air. Hydrogen (H2) on the other hand has a molecular weight of 2 g/mol and is a lot lighter than air. But what about the mixture? Balancing the redox equation for glucose give meC6H12O6 + 6 H2O -> 6 CO2 + 12 H2If we do a weighted average, we get 44 + 2 + 2 = 48, 48/3 = 16So the gas mixture in a carbon dioxide/hydrogen fart is still lighter than air, and that fart should also rise.Of course, carbon dioxide, hydrogen and methane are all odorless, and farts aren’t. But our noses are just very, very sensitive to the volatile compounds that are also in farts, so I don’t think that they will be present in large enough quantities to throw off my estimations.Oh, and all farts can be lit.
