Give the IUPAC name of the following compound
Answer:
3-phenylprop-2-enal
Explanation:
The given compound consists of a phenyl group, which is the ring
Considering the longest chain starting from the carbon atom closest to the aldehyde, CHO, functional group, the location of the phenyl group is at the 3rd carbon atom on the longest chain
C6H5-C₃H = C₂H - C₁HO
Therefore, for the name of the branched group, we have;
3-phenyl
Based on the location of the double bond, at the second carbon atom, we have;
The name of the straight chin = Prop-2-ene
The name of the aldehyde functional group, CHO, is then added at the end by indicating its position on the longest chain, which is on the first carbon, the IUPAC name of the aldehyde functional group is -al, to give;
1-al
Combining, we get
3-phenylprop-2-ene-1-al
We remove the 1, to get the IUPAC name of the compound as follows;
3-phenylprop-2-enal

Combustion of coke is a combination reaction. CO2 is not a pollutant. Then why is combustion of coke harmful?
Combustion of coke is harmful as it increases the concentration of CO2 in the atmosphere which causes global warming due to the greenhouse effect.
CO2 is not deemed a pollution until a particular threshold is reached. Rather, it aids in maintaining the temperature of the Earth. Coke combustion is hazardous because it raises the concentration of CO2 in the atmosphere, causing global warming owing to the greenhouse effect.
Burning of coke creates a lot more than simply CO2. There are a plethora of harmful and polluting byproducts. Phenolic and other organic compounds, as well as cyanides, sulphides, and ammonia, are a few examples.

What’s the difference between a learned behavior in an inherited behavior? Give one example of each
Answer:
short answers:
A learned behavior is a behavior that develops during an animal’s lifetime.
Examples of learned behaviors include tying one’s shoes or solving a math problem.
An inherited behavior is a behavior that an animal is born with.
An example of an inherited behavior is a bird building a nest.
Explanation:
Learned behaviors are those which are gradually developing in us through learning at different ages and it takes time. Inherited behaviour is innate to us which are incorporated with us by birth.
What is learned behaviour?An organism develops a learned behavior as a result of experience. In contrast to learned actions, inherent behaviors are genetically preprogrammed and can be carried out without any prior knowledge or instruction.
Certain behaviors have features that are both acquired and innate. Zebra finches, for instance, have a genetic predisposition to learn a song, but the song they sing is influenced by what they hear from their dads.
Inherited behaviors are inherited from parents to their offsprings. Such as similar nature in sound, angriness, some diseases etc. They are not gathered from any experience and are accompanied by birth.

In which of the following titrations would the solution be neutral at the equivalence point? [Hint: For a neutral equivalence point, we need both a strong acid and a strong base as analyte and titrant, respectively.]
HOCl titrated with Ba(OH)2
CH3COOH titrated with NaOH
HClO4 titrated with KOH
Sr(OH)2 titrated with H3PO4
NH3 titrated with HCl
HCl is a strong acid, and KOH is a strong base, so the equivalence point of HClO4 titrated with KOH would be basic.
The titration in which the solution would be neutral at the equivalence point is the NH3 titrated with HCl. In this titration, NH3 is a weak base, and HCl is a strong acid. At the equivalence point, all the NH3 is converted into NH4Cl, which is a neutral salt. The other titrations involve either weak acid/strong base or strong acid/weak base combinations, which would result in an acidic or basic equivalence point. For example, CH3COOH is a weak acid, and NaOH is a strong base. At the equivalence point, the solution would be basic because NaCH3COO is a basic salt.
Similarly, HCl is a strong acid, and KOH is a strong base, so the equivalence point of HClO4 titrated with KOH would be basic.

how to tell how many valence electrons an atom has?
Answer: Count only the electrons in the highest shell s and p orbitals when determining valence.
Explanation: I'm glad you asked this question. It is often not well explained. The term valence electrons is assigned to only the electrons in an element's highest energy level. These reside only in the s and p orbitals, and not the d or f, as I'll explain later. The s orbital can hold 2 electrons and the p can hold 6. Potassium, K, has an s orbital in its highest energy shell, 4. It contains only 1 electron, so it has a valency of 1.
Calcium, Ca, has 2 in its highest energy level: 4s^2, so it has a valency of 2. Moving to the right, the element scandium, Sc, add another electron, but it goes into the 3d orbital. 3d is in the 3rd energy shell, so it is not counted as a valence electron. Only after we move further right, to gallium, Ga, do we start adding electrons to the 4th energy level again - the 4p orbitals can accept up to 6 electrons. Ga has 3 valence electrons - 2 in the 4s and 1 in the 4p. Oxygen has 2 in the 2s and 4 in the 4p orbitals, for a total of 6. It is close to having a comple outer shell (2 in the 2s and 6 in the 2p). Just 2 more electrons would fill both the 2s and 2p orbitals for a total of 8 valence electrons, a stable configuration (the same configuration as thje stable gas Neon).

Hydrochloric acid (HCl) and sodium hydroxide (NaOH) react to form water and sodium chloride (NaCl). If you have 2.87 g of HCl, 3.75 g of water, and 1.98 g of NaCl, how many grams of NaOH were reacted? Your answer should go to the hundredths place.
Answer:
2.86g
Explanation:
Mass of HCl = 2.87g
Mass of water = 3.75g
Mass of NaCl = 1.98g
Unknown:
Mass of NaOH reacted = ?
Solution:
The reaction expression is given as:
HCl + NaOH → NaCl + H₂O
According to the law of conservation of mass, the mass of reactants and products must be the same.
Mass of HCl + Mass of NaOH = Mass of NaCl + Mass of H₂O
2.87g + Mass of NaOH = 1.98g + 3.75g
Mass of NaOH = 1.98g + 3.75g - 2.87g = 2.86g
0.12 g of magnesium reacted to produce 0.20 g of magnesium oxide.
Calculate the number of moles of oxygen gas (O₂) that reacted.
Relative atomic mass (A): O = 16
Mass of magnesium (Mg) = 0.12 g
Atomic mass of Mg = 24.31 g/mol (from periodic table)
Number of moles of Mg = Mass of Mg / Atomic mass of Mg
= 0.12 g / 24.31 g/mol
= 0.00494 mol
Number of moles of O₂ = Number of moles of MgO produced / 2
= 0.00650 mol / 2
= 0.00325 mol
When 12 g of Mg fully interacts with oxygen, how much MgO is formed?When the experiment is performed without the crucible cover, the magnesium oxide created reacts with any oxygen in the air. When more oxygen reacts with the magnesium, the amount of magnesium oxide generated will be larger than when the experiment was run without a cover on the crucible.
Also, any water vapour or other gases in the air may react with the magnesium oxide, influencing the final product's mass. As a result of the existence of extra reactants in the air, the mass of magnesium oxide formed will change when the crucible is not covered.

What is it called when two forms of a trait?
When two forms of a trait (such as dominant and recessive alleles) are present in an individual's genetic makeup, it is called heterozygous or hybrid.
This means that the individual has inherited different versions of the gene from each parent. In contrast, when an individual has two identical forms of a trait, it is called homozygous.
"Heterozygous" refers to an organism that has two different alleles, or versions of a gene, at a particular genetic locus. One allele is inherited from one parent, while the other allele is inherited from the other parent. For example, if an individual inherits one allele for blue eyes from one parent and one allele for brown eyes from the other parent, they are heterozygous for the eye color gene.
In contrast, an individual who inherits two identical alleles (either two blue or two brown) is homozygous for that gene. Heterozygous individuals may exhibit a dominant trait if one allele is dominant over the other, or a recessive trait if both alleles are recessive.
