which is the correct order of ease of carbon dioxide production by heating the group II metal carbonates?​
seraphim [82]

Which is the correct order of ease of carbon dioxide production by heating the group II metal carbonates?​

A) BaCO_{3}   > SrCO_{3}  >  CaCO_{3}  > MgCO_{3}

B) MgCO_{3}   > CaCO_{3}  >  SrCO_{3}  > BaCO_{3}

C) CaCO_{3}   > MgCO_{3}  >  BaCO_{3}  > SrCO_{3}

D) SrCO_{3}   > BaCO_{3}  >  CaCO_{3}  > MgCO_{3}

Answer:

Explanation:

The correct option is A:

<h2> </h2>

BaCO_{3}   > SrCO_{3}  >  CaCO_{3}  > MgCO_{3}

On the periodic table, carbonates required stronger heating as one does down the groupings in order for them to decompose. The implication is that  the stability of compounds will increase from MgCO_{3} to BaCO_{3} ​.  

 

So the carbonates will be stable according to the following order:

BaCO_{3}   > SrCO_{3}  >  CaCO_{3}  > MgCO_{3}, thus making B the correct answer.

Cheers

Describe the Barium chlorate (Ba(ClO3)2) breaks down to form barium chloride and oxygen. What is the balanced equation for this
Masteriza [31]

Answer:

Ba(ClO3)2(s)> BaCl2(s) + 3 O2(g)

Explanation

You have to balance the equation to get the same number of oxygens as on the other side with the reactants. So adding a 3 before O2 gives you six oxygens on each side.

One method for preparing a nitrile is the dehydration of a primary amide.
Olenka [21]
True because a dehydration reaction is a conversion that involves the loss of water from the reacting molecule or ion. Dehydration reactions are common processes, the reverse of a hydration reaction. Common dehydrating agents used in organic synthesis include sulfuric acid and alumina. Often dehydration reactions are effected with heating.
