In which type of reaction do two or more substances combine to produce a single substance?

melomori [17]

The correct answer is option 1. Synthesis reaction is the chemical reaction which involves two or more substances combining to form a single substance. An example is burning magnesium. The balanced reaction is 2Mg + O2 = 2MgO.

What is the molar mass of 1-butene if 5.38 × 1016 molecules of 1-butene weigh 5.00 μg?

xenn [34]

<h3>Answer:</h3>

Molar Mass = 56 g.mol⁻¹

<h3>Explanation:</h3>

Data Given:

Mass = 5.00 μg = 5.0 × 10⁻⁶ g

Number of Molecules = 5.38 × 10¹⁶ Molecules

Step 1: Calculate Moles of 1-Butene:

As we know one mole of any substance contains 6.022 × 10²³ particles (atoms, ions, molecules or formula units). This number is also called as Avogadro's Number.

The relation between Moles, Number of Particles and Avogadro's Number is given as,

Number of Moles = Number of Particles ÷ 6.022 × 10²³

Putting values,

Number of Moles = 5.38 × 10¹⁶ Molecules ÷ 6.022 × 10²³

Number of Moles = 8.93 × 10⁻⁸ Moles

Step 2: Calculate Molar Mass of 1-Butene:

As,

Mole = Mass ÷ M.Mass

Solving for M.Mass,

M.Mass = Mass ÷ Mole

Putting values,

M.Mass = 5.0 × 10⁻⁶ g ÷ 8.93 × 10⁻⁸ mol

M.Mass = 55.99 g.mol⁻¹ ≈ 56 g.mol⁻¹

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.

Explain why electrons orbit around the nucleus

Sonja [21]

In quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.
