Answer:
Polymerisation is the chemical process of monomers joining together to form polymers, often it takes many thousands of monomers to make a single polymer.
Explanation:
Methane has the alkane functional group, so the name is composed of meth- for the carbon chain, and –ane for the alkane functional group
Answer:
1. the bottom layer
2. aqueous HCI
3. the top layer
4.aqueous NaOH
5. mostly in the diethyl ether layer
Explanation:
Pure dimethylformamide is considerably more polar than hexane hence thee two solutions will form two phases with the pure dimethylformamide as the bottom layer.
If we want to extract aniline from chloroform, HCl must be added in order to give a salt that can be extracted into the aqueous layer.
For a mixture of methylene chloride and diethyl ether, the diethyl ether layer will be found as the top layer since it is considerably less polar than methylene chloride.
Benzyl alcohol can be extracted from a solution of chloroform by adding NaOH and extracting it into an aqueous layer.
A large partition coefficient for the extraction of naphthalene into diethyl ether from water means that naphthalene will be found mostly in the diethyl ether layer.
Answer:
1.602 L (or) 1602 mL
Explanation:
Molarity is the amount of solute dissolved per unit volume of solution. It is expressed as,
Molarity = Moles / Volume of Solution ----- (1)
Rearranging above equation for volume,
Volume of solution = Moles / Molarity -------(2)
Data Given;
Molarity = 0.00813 mol.L⁻¹
Mass = 1.55 g
First calculate Moles for given mass as,
Moles = Mass / M.mass
Moles = 1.55 g / 119.002 g.mol⁻¹
Moles = 0.0130 mol
Now, putting value of Moles and Molarity in eq. 2,
Volume of solution = 0.0130 mol / 0.00813 mol.L⁻¹
Volume of solution = 1.60 L
or,
Volume of solution = 1602 mL
The Element that form more compounds than all the rest is Carbon.
Elements of Carbon
<span>A molecule of the compound carbon dioxide contains one atom of the element carbon and two atoms of the element oxygen. Each oxygen atom shares a double bond with the carbon atom. Carbon is the sixth element in the periodic table and occurs in pure form as coal and diamonds.
Hopefully I helped ^.^ Mark brainly if possible~
