Answer : The correct option is, peptide bond.

Explanation :

Amino acid : Amino acid are the acid that contains two functional groups which are carboxylic group, $-COOH$ and ammine group, $-NH_2$ .

When the several amino acids join together with the help of peptide bond, they produce polypeptide chain or protein. The bond present between the two amino acid is a peptide bond. The peptide bond is formed between the nitrogen of one amino acid and carbon of another amino acid.

Covalent bond : It is formed between the two non-metal element.

Ionic bond : It is formed between the one metal and non-metal element.

Hydrogen bond : It is formed between the proton of one molecule and the electronegative atom of another molecule.

Say I grab a bunch of aluminum foil (9.5g) and ball it up. Aluminum has a specific heat of .9J/g*C. How much would the aluminum’

Brrunno [24]

Answer:

ΔT = 0.78 °C

Explanation:

Given data:

Mass of Al = 9.5 g

Specific heat capacity of Al = 0.9 J/g.°C

Temperature change = ?

Heat added = 67 J

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

67 J = 9.5 g × 0.9 j/g.°C × ΔT

67 J = 85.5 j/°C × ΔT

ΔT = 67 J / 85.5 j/°C

ΔT = 0.78 °C

Which sample contains the largest number of oxygen atoms? Select one: a. 8.0 g of carbon dioxide b. 8.0 g of potassium chlorate

adell [148]

The sample with the largest number of oxygen atoms will be calcium perchlorate.

<h3>Number of atoms in a compound</h3>

Since we are not looking at the number of moles, the mass of the compounds has no bearing on the number of atoms of oxygen.

The chemical formula for carbon dioxide is $CO_2$ . Thus, it has 2 atoms of oxygen.
The chemical formula for potassium chlorate is $KClO_3$ . Thus, it has 3 oxygen atoms.
The chemical formula for calcium perchlorate is $Ca(ClO_4)_2$ . Thus, it has 8 atoms of oxygen.
The chemical formula for sodium hydroxide is NaOH. Thus, it has 1 atom of oxygen.
