The polymerization of amino acids produces:
Delicious77 [7]

Answer:

Proteins

Explanation:

Polymerization, in chemistry, is the chemical combination of monomeric units to form a polymer. Polymers are large molecules made up of smaller units called monomers. Amino acids are the monomeric units of proteins i.e. A protein is made up of of many amino acids joined together.

Therefore, the chemical combination of amino acids will form a peptide bond between the carbon atom of the acid group and nitrogen atom of the amine group in the structure of the amino acids. This is done by the loss of a water molecule. The continuous repetition of this polymerization process will form a chain called polypeptide, which is the PROTEIN.

5. A 4.44 L container holds 0.481 mol of O2 at 22.6°C. What is the pressure of the tank?
mamaluj [8]

Answer:  The pressure of the tank will be 2.63 atm

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = ?

V = Volume of gas = 4.44 L

n = number of moles = 0.481

R = gas constant =0.0821Latm/Kmol

T =temperature =22.6^0C=(22.6+273)K=295.6K

P=\frac{nRT}{V}

P=\frac{0.481mol\times 0.0821Latm/K mol\times 295.6K}{4.44L}=2.63atm

The pressure of the tank will be 2.63 atm

"how many moles of calcium atoms are in 2.5 moles of calcium carbonate caco3"
Montano1993 [528]

Answer: -

2.5 moles of calcium atoms are in 2.5 moles of calcium carbonate CaCO₃

Explanation: -

In order to solve such types of problems, the first step would be to write the chemical formula of the compound.

The chemical formula of calcium carbonate = CaCO₃

The chemical symbol of Calcium is Ca.

From the formula of calcium carbonate we can see that

1 mole of CaCO₃ has 1 mole of Ca

2.5 mole of CaCO₃ has \frac{1 mole Ca }{1 mole CaCO₃} x 2.5 mole CaCO₃

= 2.5 mol of Ca.

∴2.5 moles of calcium atoms are in 2.5 moles of calcium carbonate CaCO₃
