MULTIPLE CHOICE QUESTION

Write the charge balance for a MgSO 4 and NaNO 3 solution that contains H + , OH − , Mg 2 + , HSO − 4 , SO 2 − 4 , MgHSO + 4 , M

irga5000 [103]

Answer :

$MgSO_4$ solution contains $Mg^{2+}$ and $SO_4^{2-}$

$NaNO_3$ solution contains $Na^{+}$ and $NO_3^{-}$

Explanation :

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

All the polyatomic ions always form an ionic compound.

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

The given compounds are, $MgSO_4$ and $NaNO_3$

$MgSO_4$ is an ionic compound which is formed by the combination of $Mg^{2+}$ cation and $SO_4^{2-}$ anion.

and,

$NaNO_3$ is an ionic compound which is formed by the combination of $Na^{+}$ cation and $NO_3^{-}$ anion.

A level chem naming isomers

anyanavicka [17]

Answer:

Butan-1-ol or Butanol

2-methylpropan-2-ol

2-methylpropan-1-ol

Butan-2-ol

Explanation:

Data Give:

Three Isomers are given

names of These =?

Details:

Isomers:

Isomers are those chemical compounds that have same molecular formula but different structures.

In the given question the compound have same molecular formula that is C₄H₉OH but the structures are different.

So due to different structures they are named differently.

The 1st and last one are straight Chains and the other 2 are branched. all the structure have four carbon atoms, one OH group and 9 hydrogen atoms.

Names are given in attachment

butan-1-ol or Butanol

As it contain 4 carbon atoms an -OH group is attached at position 1.

________________

2-methylpropan-2-ol

In this -OH and -CH₃ is attached on carbon 2

_____________

2-methylpropan-1-ol

In this -CH₃ attached at position 2 and -OH is attached on Carbon 1.

______________

Butan-2-ol

In this 4 carbons are in straight chain and a -OH group is attached on position 2 of carbon
