Hello ! I work for a chemical company and we have some disappointments with one of their products. It is an indoor deodorant that tends to ... Dissolve dyes from the packaging in which it is sold which creates an unsightly effect. We know that the discoloration is due to an aromatic compound...
I have an unknown ester with the chemical formula C9H10O2 that is used as a flavoring agent in candies. It exhibits the following H-NMR and C-NMR (Attached file: Unknown Ester NMR)
Based on the NMR spectrum I believe the unknown is benzyl acetate , as the C-NMR and the first two...
I stumbled across a formula which reads:
3Ca(Po3)2 + 10C
The paper was written in mid 19xx, in the paper it is described how that is a way to "extract" Phosphorus.
This is slightly confusing as there must be a misprint (the "o" should be capital O for Oxygen, if we assume that, does that make...
Hi everyone,I just wanted to ask if you can help me with some of the problems that I have for homework.Although they are simple to most people, to me and some of my classmates , they are not, primarily because of our teacher.Thank you in advance.
1.How many moles of Calcium chloride hexahydrate...
This is Shefin. I do research in Biotechnology. I presently focussed on the phytochemical details from plants. Here I came across the fact that most plants contains different compounds having the same molecular formula and molecular weight. Why is it so? and What is it called? what...
How do you go about solving this problem? what steps should I take? Thank you very much for any help!
11. When 3.14 g of Compound X is completely combusted, 6.91 g of CO2 and 2.26 g of H2O form. The molecular formula of Compound X is
Combustion of hydrocarbon X in excess oxygen produces 0.66g of carbon dioxide, and 0.27 g of water. At room tempertaure and pressure , X is a gas with density 1.75gdm^-3 . What could the molecular of X be?
What is the ans ? i only managed to get the empirical formula is CH2 ...
Compound X has the following composition by mass : carbon(64.3%) , 7.1% of hydrogen and oxygen (28.6%) . X reduces Fehling's solution to CuO . Copper( I) oxide .0.1 mol of X react with 4480cm3 of hydrogen gas in the presence of nickel catalyst. What 's the possible structural formula of X ...
since the compound X react with alcoholic agno3 , then why it shouldnt be aldenyde?
the ans given is A . the ans A is a ketone am i right? please help me on this.. thanks in advance!
when the following compound react with hot acidified kmno4, it will form 2 compound as in the link
can someone explain why the HOOC-COOH will be oxidised to CO2 and H2O ?
Hi guys, I have a problem here. Tried to find this for a few days now however been struggling... :confused:
My task is:
Calculate % of iodide in the tin compound of each of the three samples and hence determine the formula of the compound.
The only information I have is mass of all three...
I am trying to start with a chemical compound that hardens quickly upon exposure to air. It is meant to be unlike that of industrial superglue but more of something like quick dry cement. I have problems determining the compound to make it harden fast and durable.
Lets say we are asked to calculate the mass in grams of C6H12O6, the answer we get is 180g
but when we are asked to calculate the mass of a MOLECULE of C6H12O6, we need to divide 180g by 6.02x10^23?
Isn't the 1st question talking about one molecule of C6H12O6?
I'm trying to work our the structure of two compounds as practice for an up coming test.
The first has the molecular formula C5H9ClO2. The IR spectrum shows a strong absorption at 1725 cm-1. I've found the following signals:
a. 3.3 ppm, singlet, integration of 3
b. 3.0 ppm...
