The equation shows reactants to a neutralization reaction.
Ca²⁺ + OH⁻ → H⁺ + NO⁻. Here H binds with OH⁻ to make water. So the option c is correct.
As the answer to the question is cleared from these reactions. Firstly calcium hydroxide combines with nitric acid to form the products as follows;
Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O
Now the reaction between ionic species will be as follows
Ca²⁺ + 2OH⁻ + 2H⁺ + 2NO₃⁻ → Ca²⁺ + 2NO₃⁻ + 2H₂O
Hence OH⁻ combines with H⁺ to make H₂O(water)
OH⁻ + H⁺ → H₂O
H⁺ binds with OH⁻ to make water

Is starch an ionic or covalent compound?
Starch is a covalent compound because no ions is present in it.
A covalent bond is made from the mutual sharing of one or more pairs of electrons between two atoms. These electrons in a covalent bond are simultaneously attracted by the two atomic nuclei. A covalent bond is formed when the difference between the electronegativities of two atoms is too small for an electron transfer to occur and to form ions.
Starch is composed of long chains of glucose molecules that are bonded together through covalent bonds called glycosidic bonds. As starch contains covalent bonds it it, so it is a covalent compound.

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.

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.

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.

A solution's freezing point is lower than that of the pure solvent's.
The term "freezing point depression" is used to describe this phenomena.
DT = (Kf) is the formula for the freezing point depression (m)
The freezing point depression is represented by T f = T° f - ΔT
The pure solvent's freezing point is T°f.
The solution's freezing point is ΔTf.
Kf is the solvent's molal freezing point depression constant.
The value of Kf is typical for the particular solvent.
Kf is measured in °C/m units.
The solution's molality is given by m.
m is the amount of solute per kilogram of solvent.
m = kilogram of solvent/moles of solute
The molecular weight of sucrose is
12(12.01) + 22(1.01) + 11(16.00) = 342.34 g/mole
The number of moles of Sucrose = 17.1 / 342.34 = 0.05moles
and the concentration of the solution in moles per kilogram of water is
0.05 moles / 0.500 kg H₂O = 0.1 molal
By taking the freezing point constant for water as 1.86

What is freezing point?
When the temperature of a liquid falls below its freezing point, it transforms into a solid. According to the internationally accepted definition, freezing is the solidification phase change of a liquid or the liquid content of a substance caused by cooling.
Most substances have the same melting and freezing points; however, certain substances have different solid-liquid transition temperatures. Agar, for example, exhibits hysteresis in its melting and freezing points. It melts at 85 °C (185 °F) and solidifies at 32 °C to 40 °C (89.6 °F to 104 °F).

What is the substrate process?
A substrate in biology can be either a chemical that an enzyme can operate on or the surface that an organism (such as a plant, fungus, or animal) lives on. A substrate in geology is the surface of a rock or sediment where chemical and biological processes take place.
Geology describes it as the layer of rock or other elements that lies beneath the soil. For instance, a page is a substrate for ink to stick to, rock is a substrate for fungi, and NaCl is a substrate for a chemical reaction. The basic material on which processing is carried out is referred to as the substrate in the fields of materials science and engineering. This surface might be employed to create new films or material layers, like deposited coatings. It might serve as the foundation for the bonding of paint, adhesives, or sticky tape.
The substrate in biochemistry is a molecule that an enzyme reacts with. Chemical processes involving the substrate are catalyzed by enzymes (s). One or more products are created from the substrate, and they are then released from the active site. After that, another substrate molecule can be taken up by the active site.
