Answer:
Sugar can be obtained by evaporation.
Filtering wont work because sugar is soluble in water thus will mix to form one layer.
The correct answer is 3) 2CO2(g) ⇄ 2CO(g) + O2(g)
this is the correct one because it is a decomposition reaction and all the number of atoms is equal on both sides.
there are 2 C atoms on both sides.
and 4 O atoms on both sides.
and 1) the atoms numbers are equal on both sides but not correct as it not a
correct number as it has 1/2 O2.
and 2) CO2(g) ⇆ CO(g) + O2
the number of O atoms is not equal on both sides of the equation.
we have 2 O atoms on the left side and 3 O atoms on the right side.
so, this not a balanced equation.
4) also not correct 2CO(g) + O2 ⇆ 2CO2
as it is not a decomposition reaction and the 2CO & O2 are as reactants not products.
so the correct answer is 3) 2CO2(g) ⇆ 2CO(g) + O2(g)
Answer:
Adduct, donate, accept
Explanation:
Lewis acids are those having suitable vacant orbital for electron acceptance and forming a covalent bond with an electron rich species. Example: 
(B has vacant 2p orbital for electron acceptance)
Lewis bases are those having energetically available unshared electrons that can be donated to an electron deficient species and form a covalent bond. Example: 
(N has energetically available lone pair)
So, product of Lewis acid-base reaction is an adduct (
) where a new covalent bond is formed between B and N.
The molecular formula of quinine is C20H<span>24N2</span>O<span>2. For every 1 mole of quinine molecule, there are 20 moles of carbon. Simply multiplying 6.0 moles by 20, we get, 120 moles.
Therefore, there are 120 moles of carbon in 6.0 moles of quinine.</span>
