Answer:

True

Explanation:

In general, metals are located on the left of the periodic table. Nonmetals are on the right. This means that they are on opposite sides.  So the answer is True.

The Lewis acid-base definition involves the classification of some substances as acids or bases that the other two definitions (Arrhenius and Bronsted-Lowry) miss.

This is because the Lewis definition focuses on the interaction between electron pairs, allowing for the identification of substances as Lewis acids (electron-pair acceptors) or Lewis bases (electron-pair donors) that may not exhibit typical acid or base behavior according to the Arrhenius or Bronsted-Lowry definitions.

1. Arrhenius Definition: An acid is a substance that increases the concentration of H+ ions when dissolved in water, while a base is a substance that increases the concentration of OH- ions.

2. Brønsted-Lowry Definition: An acid is a proton (H+) donor, and a base is a proton (H+) acceptor.

3. Lewis Definition: An acid is an electron-pair acceptor, and a base is an electron-pair donor.

The Lewis definition is broader than the Arrhenius and Brønsted-Lowry definitions because it includes substances that don't necessarily involve H+ ions. Thus, it classifies some substances as acids or bases that the other two definitions miss.

Alkynes can undergo oxidative cleavage with ozone followed by hydrolysis to form carboxylic acids. To determine which alkyne will give only one carboxylic acid with the molecular formula C4H8O2, we need to consider the possibilities.

The molecular formula C4H8O2 suggests the presence of four carbon atoms, eight hydrogen atoms, and two oxygen atoms. Let's consider the possible alkyne options and check if they meet this requirement:

1. Ethyne (acetylene): C2H2

  When acetylene reacts with ozone and water, it forms two molecules of carbon dioxide (CO2) and two molecules of water (H2O). Therefore, it does not yield a carboxylic acid with the given molecular formula.

2. Propyne: C3H4

  Propyne, when reacted with ozone and water, gives two molecules of acetic acid (CH3COOH) and one molecule of formaldehyde (CH2O). Thus, it does not yield a carboxylic acid with the given molecular formula.

3. 1-Butyne: C4H6

  1-Butyne, upon reaction with ozone and water, can yield one molecule of butanoic acid (C3H7COOH) and one molecule of formaldehyde (CH2O). This corresponds to the molecular formula C4H8O2 and satisfies the given criteria.

Based on the options provided, the alkyne that will react with ozone, followed by water, to give only one carboxylic acid with the molecular formula C4H8O2 is 1-Butyne.

To form a dipeptide between Alanine and Leucine, we have to join the carboxyl group (COOH) of Alanine with the amino group (NH₂) of Leucine via a peptide bond. The resulting molecule will have a zwitterionic form. The zwitterionic form of the dipeptide will have both a positive and a negative charge.

A dipeptide is a molecule made up of two amino acid residues joined together via a peptide bond. A peptide bond is a bond between the amino group (NH₂) of one amino acid and the carboxyl group (COOH) of another amino acid. Amino acids are the building blocks of proteins. Alanine and Leucine are two of the twenty common amino acids found in nature.

A zwitterion is a molecule that has a positive charge on one part of the molecule and a negative charge on another part of the molecule. Zwitterions are electrically neutral overall. They are formed when a molecule that has both acidic and basic functional groups is dissolved in a solvent. The acidic and basic groups react with each other to form a neutral molecule that has both positive and negative charges. The zwitterionic form of an amino acid is the form that is found in proteins.

The chemical formula for Alanine is C₃H₇NO₂, and the chemical formula for Leucine is C₆H₁₃NO₂. To form a dipeptide between Alanine and Leucine, we have to join the carboxyl group (COOH) of Alanine with the amino group (NH₂) of Leucine via a peptide bond.

Ernest Rutherford’s model of the atom, first proposed in 1911, is one of the most important discoveries in the history of science. This model of the atom was revolutionary, as it improved upon J.J. Thomson’s “plum pudding” model and established a new understanding of the structure of the atom.

Rutherford’s model of the atom proposed that the atom was composed of a small, positively charged nucleus surrounded by negatively charged electrons. This structure was in contrast to Thomson’s model, which proposed that the atom was a homogeneous “plum pudding” composed of positive and negative charges. Rutherford’s model also proposed that the electrons orbited the nucleus in a manner similar to the way planets orbit the sun in the solar system, although the electrons did not have set orbits.

Rutherford also established that the alpha-particles (helium nuclei) are four times as heavy as a hydrogen atom. This discovery was made through the famous Gold Foil Experiment, in which Rutherford and his team of scientists sent alpha particles through a thin sheet of gold foil. The results of this experiment led Rutherford to conclude that the atom was not homogeneous.

The rate constant   for a first-order reaction is 0.54 s-1. What is the half-life of this reaction if the initial concentration is 0.34 M 1.3 s

Rate constant is the rate at which a chemical reaction moves forward. It is frequently described in terms of either the concentration of a reactant that is consumed in a unit of time or the concentration of a product that is generated in a unit of time (amount per unit volume).

You may also define it in terms of how much of the reactants are used up or how much of the products are produced in a given amount of time. Depending on the nature of the interacting substances, the type of chemical transformation, the temperature, and other conditions, chemical reactions can move along at dramatically different rates. In general, covalent bond breaking reactions take far longer than those involving the combination of atoms or ions (electrically charged particles).

There have been many other observed substitution reactions involving benzene; the five reactions that have proven to be the most beneficial are described here (chlorination and bromination are the most common halogenation reactions). The term "Electrophilic Aromatic Substitution" is usually used to refer to these reactions since the chemicals and conditions that are used in them are electrophilic. In order to carry out the first stage of the substitution reaction, the catalysts and co-reagents are used to produce the powerful electrophilic species that are required. The particular electrophile that was hypothesized to have a role in each distinct type of reaction is presented in the column to the right.

Algae blooms are most often caused by eutrophication.

Algae blooms are are dense layers of tiny green plants that occur on the surface of lakes and other bodies of water when there is an overabundance of nutrients (primarily phosphorus) on which algae depend.

Algae species tend to proliferate in growth (bloom) in the presence of abundance nutrients. This abundance of nutrients is as a result of a process called eutrophication.

In a neutral atom, the number of protons, which is the atomic number, equate the number of electrons.

According to this question, the transparent subatomic particle inside the atom's nucleus is proton while the blue colored particle is the neutron.

The limiting reactant in this reaction is hydrogen gas.2 g of hydrogen  gas will produce about 254 of HI. Then, 13.4 g will produce 1702 g of HI.

A limiting reactant in a reaction is the reactant which is fewer in amount or consume early without complete reaction with other reactants. Hence, as soon as this reactant is consume, the reaction stops.

The given reaction of the formation of HI can be written as follows:

H₂ + I₂ → 2HI

Atomic mass of H= 1 g/mol

molecular mass of H₂ = 2g/mol

As per the balanced chemical equation of the reaction, one mole or 2 g of hydrogen gas produce 2 moles of hydrogen iodide.

molar mass of HI = 127 g/mol

mass of 2 moles = 127 × 2 = 254 g.

2 of hydrogen produces 254 g HI. Then , 13.4 g of H₂ produces :
