2018年3月22日 · C_5H_11 We have decane, the alkane with a chemical formula of C_10H_22. The empirical formula of a substance has the smallest ratio between the elements its composed of. Here, we got the carbon to hydrogen ratio as 10:22. So, we need to find the greatest common factor between the two numbers. 10=2xx5 22=2xx11 As you can see here, the greatest …

2016年12月1日 · The required alkane is a Decane (C_10H_22). This is a simple calculation. The general formula for alkanes is C_n H_(2n+2). So, an alkane having 10 carbon atoms will surely have 22 hydrogen atoms, according to the given formula. So, the molar mass of decane is equal to: =(10xx12)+(22xx1) grams. =142 grams. Now, 142 lies between 140 & 150.

2018年6月11日 · The complete combustion of decane is as follows: #underbrace(2C_10H_22(g))+31O_2(g)->20CO_2(g)+22H_2O(g)+Delta#

2018年5月6日 · undecane Given: decane (10 carbons) undecane (11 carbons) dodecane (12 carbons) tridecane (13 carbons) tetradecane (14 carbons) pentadecane (15 carbons) hexadecane (16 carbons) heptadecane (17 carbons) octadecane (18 carbons) nonadecane (19 carbons) eicosane (20 carbons)

2017年8月18日 · C_11H_24 -> C_2H_4 + C_3H_6 + C_6H_14 The starting molecule in the question, undecane, will break down into three products. Two are listed in your question: ethene and propene (these are alkenes). The third product is an alkane that consists of the "leftover" carbons and hydrogens. Ethene has the formula C_2H_4. Propene has the formula C_3H_6.

2017年4月25日 · And #"decane"#, #C_10H_22# has a whopping 75 structural isomers. And this illustrates the structural complexity of the alkanes. Clearly, you would not be asked to identify all the structural isomers of even heptane. You might be asked to …

2017年1月3日 · Here's how I would do it. Step 1. Draw a 10-carbon (decane) chain. "decane" Step 2. Number the carbons from left to right. Attach an isopropyl group to carbon 4. "4-isopropyldecane" Step 3. Attach a sec-butyl group to carbon 5. "4-isopropyl-5-sec-butyldecane" And you have the structure.

2016年1月18日 · Decane #"C"_10"H"_22# Using this data, you can see butane is in forth place therefore having only 4 carbon atoms in its chemical formula. The 'but-' in butane tells you number of carbon atoms in the molecule. You would need to know the data above in order to know how many carbon atoms there are in any molecule.

2018年4月16日 · Here's a list for number of isomers for Methane (1 C) - Decane (10 C): Methane - 1 Ethane - 1 Propane - 1 Butane - 2 Pentane - 3 Hexane - 5 Heptane - 9 Octane - 18 Nonane - 35 Decane - 75. It gets quite crazy after this point. For …

2014年10月7日 · You start by determining the empirical formula for the compound. Determine the mass in grams of each element in the sample. If you are given percent composition, you can directly convert the percentage of each element to grams. For example, a molecule has a molecular weight of 180.18 g/mol. It is found to contain 40.00% carbon, 6.72% hydrogen and …
