When a protein folds in the cytoplasm, what class of amino acids tends to be found in the interior core of the protein?.

elena-14-01-66 [18.8K]

The Law of Definite Proportions (or Proust's Law) states that in a single chemical compound (such as H2O or CO) the ratio of it's component elements is a fixed whole number ratio.

The Law of multiple proportions applies when two or more elements/compounds have multiple ways of combining into different compounds.

For each of the following compounds, state whether it is ionic or covalent. If it is ionic, write the symbols for the ions invol

Elden [556K]

(A) NF3 covalent compound

(B) BaO ionic bond.

(C) NH4)2CO3 ionic bond.

(D) Sr(H2PO4)2 covalent compound

(E) IBr covalent compound

(F) Na2O ionic bond.

<h3>What are a covalent compound and ionic bond?</h3>

Covalent bonds form when two or more additional nonmetals combine. For instance, both hydrogen and oxygen are nonmetals, and when they connect to make moisture, they do so by forming covalent bonds. Combinations that are composed of only non-metals or semi-metals with non-metals will demonstrate covalent bonding and will be classified as molecular combinations.

As a broad rule of thumb, combinations that involve a metal binding with either a non-metal or a semi-metal will show ionic bonding. Therefore, the compound created from sodium and chlorine will be ionic (a metal and a non-metal). Nitrogen monoxide (NO) will be a covalently bound molecule (two non-metals), silicon dioxide (SiO2) will be a covalently bound molecule (a semi-metal and a non-metal) and MgCl2 will be ionic (a metal and a non-metal).

A polyatomic ion is an ion comprised of two or more particles that have a commission as a group (poly = many). The ammonium ion (see figure below) consists of one nitrogen atom and four hydrogen atoms. Concurrently, they constitute a single ion with a 1+ charge and a formula of NH4+. The carbonate ion (see figure below) consists of one carbon particle and three oxygen atoms and maintains a comprehensive charge of 2−. The procedure of the carbonate ion is CO32−.

When a solute is added to a solution why does it remain homogeneous?

Olenka [21]

<h3>Answer:</h3>

When a solute is added to a solution, it remains homogeneous because the solute is soluble in given solvent.

<h3>Explanation:</h3>

Homogeneous mixtures, also called true solutions are those mixtures in which the components proportions are same throughout in any given sample. For example, the mixture of table salt (NaCl) and water. When the solution is unsaturated and further NaCl is added to it, it will dissolve the NaCl because the saturation point is still not reached. Remember, as "<em>Like Dissolves Like</em>" NaCl being polar in nature will interact with water molecules and will dissociate into Na⁺ and Cl⁻ ions surrounded by δ- O and δ+ H atoms of water molecules.

<h3>Conclusion:</h3>

In order to form a Homogeneous mixture the solution must be unsaturated, solvent must have affinity for incoming solute particles and the size of solute should be equal to 1 Â (Angstrom).

If a steel container holds 3.50 moles of hydrogen gas and 3.50 moles of helium gas, and the total pressure is 4.00 atm., what is

Sunny_sXe [5.5K]

Answer:

1. Partial pressure of H₂ = 2 atm

2. Partial pressure of He = 2 atm

Explanation:

The following data were obtained from the question:

Mole of H₂ = 3.50 moles

Mole of He = 3.50 moles

Total pressure (Pₜ) = 4 atm

Partial pressure of H₂ =?

Partial pressure of He =?

Next, we shall determine the mole fraction of each gas this can be obtained as follow:

Mole of H₂ = 3.50 moles

Mole of He = 3.50 moles

Total mole = Mole of H₂ + Mole of He

Total mole = 3.50 + 3.50

Total mole = 7 moles

Mole fraction of H₂ = mole of H₂ / Total mole

Mole fraction of H₂ = 3.5/7

Mole fraction of H₂ = 0.5

Mole fraction of He = mole of He / Total mole

Mole fraction of He = 3.5/7

Mole fraction of He = 0.5

1. Determination of the partial pressure of H₂.

Mole fraction of H₂ = 0.5

Total pressure (Pₜ) = 4 atm

Partial pressure of H₂ =?

Partial pressure of H₂ = Mole fraction of H₂ × Pₜ

Partial pressure of H₂ = 0.5 × 4

Partial pressure of H₂ = 2 atm

2. Determination of the partial pressure of He.

Total pressure (Pₜ) = 4 atm

Partial pressure of H₂ = 2 atm

Partial pressure of He =?

Total pressure (Pₜ) = Partial pressure of H₂ + Partial pressure of He

4 = 2 + Partial pressure of He

Collect like terms

Partial pressure of He = 4 – 2

Partial pressure of He = 2 atm
