Answer:
C3H5NO2
Explanation:
C = 41.37%;
H = 5.75% ;
N= 16.09 %;
O= (100 - 41.37 - 5.75 - 16.09)% = 36.79 %.
In 100 g of substance we have
C = 41.37 g;
H = 5.75 g ;
N= 16.09 g;
O = 36.79 g.
Molar mass (C) = 12 g/mol;
Molar mass(H) =1 g/mol;
Molar mass(N)= 14 g/mol;
Molar mass(O) = 16 g/mol.
C = 41.37 g* 1 mol/12g = 3.4475 mol;
H = 5.75 g *1 mol/1g = 5.75 mol;
N= 16.09 g*1mol/14g = 1.1493 mol;
O = 36.79 g* 1mol/16g = 2.2994 mol.
The Empirical formula shows ratio of moles of elements in the substance , so
C : H : N : O = 3.4475 mol : 5.75 mol : 1.1493 mol : 2.2994 mol =
= (3.4475 mol /1.1493 mol) : (5.75 mol/1.1493 mol) : (1.1493 mol /1.1493 mol) : :( 2.2994 mol/1.1493 mol) = 3 : 5 : 1 : 2
C : H : N : O = 3 : 5 : 1 : 2
C3H5NO2
Answer: Organic compounds ending with the name (-ene) indicate that the compounds contain double bonds in their molecules.
Explanation:
Organic compounds are those molecules that contains carbon atoms (as their main element), hydrogen and oxygen which are usually present. The presence of numerous organic compounds is due to the following properties of carbon:
--> the exceptional ability of carbon atoms to catenate, that is, to combine with one another to form straight chains, branched chains or ring compounds containing many carbon atoms.
--> The ease with which carbon combines with hydrogen, oxygen, Nitrogen and halogens
--> The ability of carbon atoms to form single, DOUBLE or triple bonds.
The organic compound that has the name ending with -ene are known as the alkenes. The members of the alkene series are formed from the alkanes by the removal of two hydrogen atoms and the introduction of a DOUBLE BOND in the carbon chain. They are named after the corresponding alkanes by changing the -ane ending to -ene.
Note: the systematic name of a compound is formed from the root hydrocarbon by adding a suffix and prefixes to denote the substitution of the hydrogen atoms.
1)Delta H=(Delta H of reactants)-(Delta H of products)
2)And we know CO have 3 bond CO and CO2 have 2 bond that each of them are 2 bond, please see the picture!
so lets answer it:
The solution will be acidic if it contains a greater concentration of hydronium ions and acidic if it contains a greater concentration of hydrogen ions. So High concentrations of hydrogen lead to low pH(acidic) whereas low levels of hydrogen ions result in in a high pH(basic)
