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

Write the given numbers in standard notation, maintaining the same number of significant figures.
svetlana [45]

Answer:

0.0761.

0.0059.

Explanation:

Hello!

In this case, since the writing of numbers in standard notation given the scientific notation requires adding zeros to the left of the first nonzero digit, for the first number, we need to add two zeros as seven is the third digit position:

0.0761.

Next, we need to add three zeros as 5 would be the fourth digit:

0.0059.

Best regards!

How does the structure of amino acids allow them to form a polypeptide
melamori03 [73]
<span>Amino acids which are known to be linked by peptide bonds they form polypeptide chains.

 Proteins are linear polymers are formed by way of linking an a-carboxy group of one amino acid to a-amino of different amino acids which have peptide bond. The formation which results from two amino acids which result in a loss of a water molecule. The best process of the reaction is hydrolysis.</span>
