Deuterium is an isotope of hydrogen (H) that has:

Which of the following statements about hybridization are true? Select all that apply: Hybrid orbitals exist in isolated atoms.

Leokris [45]

Answer:

True:

Hybrid orbitals within the same atom have the same energy and shape.
Hybrid orbitals are described mathematically as a linear combination of atomic orbitals.
An atom can have both hybridized and unhybridized orbitals at the same time.

Explanation:

Hybrid orbitals do not exist in isolated atoms. They form only in covalently bonded atoms.

Hybridization happens when several atomic orbitals combine to form other orbitals with the same energy and greater stability.

A set of hybrid orbitals is generated by combining atomic orbitals. The number of hybrid orbitals in a set is equal to the number of atomic orbitals that combined to produce the set.

Hybrid orbitals overlap to form σ bonds. Unhybridized orbitals overlap to form π bonds, and both can appear in an atom at the same time.

Please help ASAP thank you!!!!!

natali 33 [55]

Answer:

The new volume is 66.3 mL

Explanation:

Boyle's law states that pressure and volume are inversely proportional, and that P1V1=P2V2

P1 = 0.428 atm

P2=1.55 atm

V1 = 240 mL

V2 = ??

(0.428)(240)=(1.55)(V2)

102.72 = 1.55x

x = 102.72/1.55 = 66.27 mL.

Why is potassium nitrate classified as aj electrolyte?

baherus [9]

<span>KNO3 is a strong electrolyte because it completely dissociates into ions in water. Dissociates means it immediately breaks into ions of K+ (potassium cation) and NO3- (nitrate anion). Thus it also conducts electricity very well compared to a weak electrolyte.</span>

Glucose, C6H12O6,C6H12O6, is used as an energy source by the human body. The overall reaction in the body is described by the eq

Ilia_Sergeevich [38]

Answer:

Mass of oxygen = 61.824 g

Mass of carbon dioxide = 85.01 g

Explanation:

Given data:

Mass of glucose = 58 g

Mass of carbon dioxide = ?

Mass of oxygen = ?

Solution:

First of all we will write the balanced chemical equation,

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

Moles of glucose:

Number of moles = mass / molar mass

Number of moles = 58 g/180 g/mol

Number of moles = 0.322 mol

Now we compare the moles of oxygen with glucose from balance chemical equation.

C₆H₁₂O₆ : O₂

1 : 6

0.322 : 0.322×6 = 1.932 mol

Mass of oxygen:

Mass of oxygen = number of moles × molar mass

Mass of oxygen = 1.932 mol × 32 g/mol

Mass of oxygen = 61.824 g

Now we compare the moles of carbon dioxide with moles of glucose and oxygen.

C₆H₁₂O₆ : CO₂

1 : 6

0.322 : 0.322×6 = 1.932 mol

O₂ : CO₂

6 : 6

1.932 : 1.932

Mass of carbon dioxide;

mass of carbon dioxide = number of moles × molar mass

mass of carbon dioxide = 1.932 mol × 44 g/mol

mass of carbon dioxide = 85.01 g
