Yes, 20 grams of salt can be dissolved in 100 mL of water.
What is solubility?Solubility is the ability of a substance to dissolve in a liquid or to be dispersed in another substance. It is a physical property of a substance that determines how much of a solute can be dissolved in a particular solvent. Solubility is a measure of the maximum amount of solute that can be dissolved in a given solvent at a particular temperature and pressure. Solubility is an important factor to consider when formulating products as it affects the concentration of the active ingredient or solute in the end-product.
The amount of salt that can be dissolved in a given amount of water is determined by the solubility of the salt. The solubility of salt in water is typically around 357 grams per liter, so 20 grams of salt can be dissolved in approximately 56 milliliters of water.

Sequence Determination of the Brain Peptide Leucine Enkephalin A group of peptides that influence nerve transmission in certain parts of the brain has been isolated from normal brain tissue. These peptides are known as opioids, because they bind to specific receptors that also bind opiate drugs, such as morphine and naloxone. Opioids thus mimic some of the properties of opiates. Some researchers consider these peptides to be the brain�s own pain killers. Using the information below, determine the amino acid sequence of the opioid leucine enkephalin. Explain how your structure is consistent with each piece of information.(a) Complete hydrolysis by 6 M HCl at 110 C followed by amino acid analysis indicated the presence of Gly, Leu,Phe, and Tyr, in a 2:1:1:1 molar ratio.(b) Treatment of the peptide with 1-fluoro-2,4-dinitrobenzene followed by complete hydrolysis and chromatography indicated the presence of the 2,4-dinitrophenyl derivative of tyrosine. No free tyrosine could be found.(c) Complete digestion of the peptide with chymopepsin followed by chromatography yielded free tyrosine and leucin plus a tripeptide containing Phe and Gly in a 1:2 ratio.
Option C) "are digested by proteases into both opiate and non-opiate peptides" is the correct response.
Like all other propeptides, the opioid propeptides is a protein precursor that must be cut into a smaller form to become active. Proteases convert the opioid propeptides into opiate and non-opiate peptides, the latter of which may or may not be active. Enkephalins, endorphins, and dynorphins, which are opiate peptides, work by blocking secondary systems, such as those that affect how pain is perceived.
The opioid receptors are essential signalling molecules in the brain that the leucine-enkephalin binds to. They include four peptide bonds in total. These are naturally occurring ligands that function as neurotransmitters and have morphine-like properties.

click on those molecules below which have a dipole moment
When there is a separation of charge, dipole moments happen. Dipole moments, which result from variations in electronegativity, can happen between atoms in a covalent link or between two ions in an ionic bond.
The dipole moment increases with the difference in electronegativity. The size of the dipole moment is also affected by the distance between the charge separations. The polarity of the molecule is determined by the dipole moment. A dipole moment is produced when electrons are distributed unevenly among atoms in a molecule. This happens when one atom possesses a lone pair of electrons and the difference in electronegativity vector points in the same direction, or when one atom is more electronegative than another, causing that atom to pull more strongly on the shared pair of electrons. The water molecule, which consists of one oxygen and two hydrogen atoms, is one of the most prevalent instances. Each hydrogen has a partial positive charge, while oxygen has a partial negative charge due to variances in electronegativity and lone electrons.

What is Molecular mass?
Molecular mass is the sum of the atomic masses of all the atoms present in a molecule. It is an important property of molecules that is used in determining the chemical and physical properties of the molecule. Molecular mass is usually expressed in units of atomic mass units (amu) or daltons (Da). It is important to note that the molecular mass of a compound is not necessarily equal to the sum of the atomic masses of its constituent atoms, as the atoms in a molecule may be bound together by covalent bonds, which can alter their individual masses. Molecular mass can be calculated by adding the masses of the individual atoms present in the molecule. This value can be used to determine the identity of the molecule and its properties. Additionally, the molecular mass of a compound can be used to calculate the molar mass of the compound, which can be used to calculate the amount of a substance present in a given volume.

Answer:
Study 'atom'
Explanation:
atoms are in the building blocks for molecules. the atom has protons and neutrons in its nucleus and electrons revolving around it. An atom can survive in its surrounding by either sharing electrons or by transferring electrons. Protons are positively charged and electrons are negatively charged. They are also called subatomic particles. When atoms lose electrons they get positively charged, and when they gain electrons they get negatively charged. When a metal is reacting with a non-metal, the metal is positively charged and transports an electron to the non-metal. The metal becomes positively charged and the nonmetal becomes negatively charged. the metal becomes the cation and the nonmetal becomes the anion. Thus, reactivity can cause gain or loss of charges.
When one s and three p orbitals hybridize?
Since the number of hybrid orbitals equals the number of atomic orbitals, 4 hybrid orbitals are created by combining 4 atomic orbitals of the same atom.
Thus, four hybrid orbitals with a tetrahedral structure will be formed by the 1 s and 3 p orbitals.
What is Hybridization ?The process of hybridization is the mixing of atomic orbitals with the same energy levels to create an equal number of new hybrid orbitals. This mixing typically produces hybrid orbitals with completely distinct energies, geometries, etc.
When two atomic orbitals in a molecule combine to generate a hybrid orbital, the energy of the orbitals of the individual atoms is redistributed to give orbitals of equivalent energy. Hybridization is the name of this procedure.

to remove 99% of benzene (c6h6) from groundwater contaminated with 5 mg/l benzene using advanced oxidation. if the groundwater is pumped at 100 gallon per minute, how much benzene
After solving the equation benzene is 2.698 kg is the correct answer.
Description of the answer
1 day = 24 hrs = 24×60 minute = 1440 minutes
concentration of benzene in groundwater = 5 mg/l
100 gallon = 378.541 L
100 gallon/minute = 378.541 L/minute
100 gallon (378.541 l) benzene contaminated groundwater is being pumped per minute, therefore the volume of groundwater being pumped in one day (i.e. 1440 minutes) = (378.541 × 1440) l = 545099.04L
Since 1 l groundwater is contaminated with 5 mg benzene, therefore 545099.04 l groundwater is contaminated with = (545099.04 × 5) mg = 2725495.2 mg = 2725.495 g = 2.725 kg
Thus, 545099.04 l groundwater is pumped per day, which contains a total of 2.725 kg benzene as contamination.
Since 99% benzene from groundwater has to be removed, therefore benzene waste (kg) needed to be treated per day = (2.275 × 99 / 100) kg = 2.698 kg.
