An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
Oleic acid belongs to class of alkene and in alkenes, addition of 
across 
that is carbon carbon double bond results in the formation of alkane as a product in the presence of specific catalyst such as nickel, palladium and platinum. The reaction is said to be hydrogenation reaction.
Oleic acid (
) consist of 17 carbon atoms attached to 33 hydrogen atoms with one double bond between two carbon atoms and one carboxylic group i.e.(
). When oleic acid is hydrogenated or reacts with hydrogen in the presence of catalyst, then the carbon carbon double breaks by the addition and alkane product i.e. stearic acid (
) is formed.
The chemical reaction is shown in the image.
Answer:
The absolute uncertainty is 10%.
Explanation:
The absolute uncertainty, sometimes referred to as absolute error, is the size of the possible range of values where by the actual or true value of a measurement probably lies.
The uncertainty of the 50 mL beaker is given as ± 10%. This implies that the volume recorded using the beaker will either be 10 % above or below the actual volume.
The absolute uncertainty ignores the direction of the error, whether above or below, and is mostly concerned with the magnitude of the error. We simply ignore the signs of the uncertainty and this will give the value of the absolute uncertainty.
Answer:
0.1 moles of magnesium
Explanation:
Mg(s) + 2CH3COOH(aq) -------> Mg(CH3COO)2(aq) + H2(g)
Since the reaction is 1:2 in mole ratio,
1 mole of magnesium reacts with 2 moles of ethanoic acid
x moles of magnesium will react with 0.2 moles of ethanoic acid
2x = 0.2
x = 0.2/2 = 0.1 moles of magnesium used
Answer:
my teacher would let u say the density to mass is the ratio but i think everyone's different
