Citric acid is a naturally occurring compound. what orbitals are used to form each indicated bond? be sure to answer all parts.2
Rina8888 [55]

Answer : The orbitals that are used to form each indicated bond in citric acid is given below as per the attachment.

Answer 1) σ Bond a : C has SP^{2}  O has SP^{2} .

Explanation : The orbitals of oxygen and carbon which are involved in SP^{2} hybridization to form sigma bonds. This is observed at 'a' position in the citric acid molecule.

Answer 2) π Bond a: C has π orbitals and  O also has π  orbitals.

Explanation : The pi-bond at the 'a'position has carbon and oxygen atoms which undergoes pi-bond formation. And has pi orbitals of oxygen and carbon involved in the bonding process.

Answer 3) Bond b:  O SP^{3}  H has only S orbital involved in bonding.

Explanation : The bonding at 'b' position involves oxygen SP^{3} hydrogen atoms in it. It has SP^{3} hybridized orbitals and S orbital of hydrogen involved in the bonding.

Answer 4) Bond c:   C is SP^{3}  O is also SP^{3}

Explanation : The bonding involved at 'c' position has carbon and oxygen atoms involved in it. Both the atoms involves the orbitals of SP^{3} hybridized bonds.

Answer 5) Bond d:   C atom has SP^{3}  C atom has SP^{3}

Explanation : At the position of 'd' the bonding between two carbon atoms is found to be SP^{3}. Therefore, the orbitals that undergo SP^{3} hybridization are SP^{3}.

Answer 6) Bond e : C1 containing O SP^{2}    

C2 is SP^{3}

Explanation : The carbon atom which contains oxygen along with a double bond has SP^{2} hybridized orbitals involved in the bonding process; whereas the carbon at C2 has SP^{3} hybridized orbitals involved during the bonding. This is for the 'e' position.

a large piece of jewelry has a mass of 132.6 g. a graduated cylinder initially contains 48.6 ml water. when the jewelry is subme
Tresset [83]

The jewelry is submerged in the graduated cylinder, the total volume increased to 61.2 ml mass of the water in the graduated cylinder is 128.5 gram.

<h3>What is density?</h3>

Density is a amount of a substance per unit area of the volume of the mass and it is the ratio of mass and the volume unit is centimeter cube.

The density of the substance = mass / volume

substituting the value in the equation,

Density = 132.6 / 48.6 = 2.1 centimeter cube.

         mass = density  volume

         mass = 2.1  61.2

         mass = 128.5 gram.

Therefore,  mass of the water in the graduated cylinder is 128.5 gram if jewelry is submerged in the graduated cylinder, the total volume increased to 61.2 ml.

17. The equation below represents a chemical reaction that occurs in living cells.
RSB [31]

Answer:

36 atoms

Explanation:

  • C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy

The reactants are in the left side of the equation. <u>First we determine how many atoms are there in the C₆H₁₂O₆ molecule</u>:

  • 6 C atoms + 12 H atoms + 6 O atoms = 24 atoms in total

There are two atoms in a O₂ molecule, and there are 6 O₂ molecules in the equation:

  • 2 * (6 O atoms) = 12 atoms in total

The total number of atoms in the reactants is

  • 24 + 12 = 36 atoms
