What precautions should be observed when an aqueous sodium carbonate solution is used to extract an organic solution containing

traces of acid?
Chemistry

Vladimir [108]3 years ago

<span>The biggest precaution that should be followed is to not wall the separatory funnel off too tightly. When the sodium carbonate solution is used, the acid will react with it to create carbon dioxide. This can build up in the funnel, leading to an increase in pressure that could cause a rupture if enough is created.</span>

What type of central-atom orbital hybridization corresponds to each electron-group arrangement:
galina1969 [7]

Tetrahedral arrangement is resulted upon mixing one s and three p atomic orbitals, resulting in 4 hybridized sp^3 orbitals → sp^3 hybridization.

<h3>What is orbital hybridization?</h3>

In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.

For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.

Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.

A student calculates that the volume of his textbook is 991.880 cm3. what is the volume written with 3 significant figures?
k0ka [10]

The volume of the textbook calculated by the student written to 3 significant figures is 992cm³

  • According to this question, a student calculates the volume of his textbook and arrived at an answer of 991.880 cm³.

  • To round up this digit to 3 significant figures, which means that only 3 significant numbers should appear in the answer.

  • To do this, the number after the third number is 8, which means we can round up the value of 1 to 2. Hence, the volume of the textbook calculated by the student is 992cm³ in 3 s.f.
