1. Why
was sulfanilamide mixed with DEG, raspberry flavoring, and saccharine?

Answer:

Electrovalent/ Ionic bond is formed between Fe and Cl

Answer:

Here's a pretty short answer :D

Explanation:

Solids have definite volume and shape, liquids have definite volume but take the shape of their containers unlike solids. Gases don't have definite shape or volume, and plasma is somewhat gas because its particles are far apart from each other - but - gases are electrically neutral while plasma has a charge.

Answer:

Question 1:

• In A, the main carbon has four bonds [two double bonds ] i.e; (=C=) hence it cannot allow any incoming electron. This makes it thermodynamically stable because it's reactivity carbon is fully bonded.

In B, the main carbon has only three bonds i.e;

(=C–) hence it will allow only one pair of incoming electrons hence reaction taking place.

Question 2:

Note: Any halo-alkane or alkyl-halide such as methyl iodide, methyl chloride, ethyl bromide are reagents used to add alkyl groups to amide molecules.

• So, Methyl Iodide will not react with C because C lacks an amide or nitrile group. To add an alkyl group to C, we shall use potassium hydroxide and any alcohol in presence of dry ether at room temperature.

• Methyl Iodide will react with D because D has an amide group which is electron efficient hence reaction will take place so easily.

Question 3

Note: Nucleophiles are electron donating molecules.

Electrophiles are electron recipients.

• F will react with nucleophiles because F has a carbonyl group i.e; (–HC=O ) which is an electron recipient. But this occurs after the oxygen atom reacting with an hydroxide to form an oxide.

E will not react, because the main carbon has a double bond which are nucleophiles.

Answer:

Explanation:

There are 6 32S atoms and 2 36S atoms

Their respective contributions to the average aomic mass is (6*32)=192, and (2*36)=72.  Added together, this makes 264 total.  Divide by the total number of atoms, 8.  (264/8) = 33.00

The weighted atomic mass of these S atoms is 33.00 amu (atomic mass units)

Answer:

This is true. Each element has a specific number of protons in the nucleus. This also means the electrons of that usually element are the same.

Explanation:

The given statement exists true. The number of protons in each element varies. The number of protons in the nuclei of any one of an element's atoms is the element's atomic number. The mass number of an atom is the sum of the protons and neutrons in the atom.

The atomic number of an atom refers to how many protons it contains (Z). This number is crucial because it is exclusive to the atoms of a particular element. Every element has a different number of protons in its atoms, but every element has the same number of protons in all of its atoms.

Atoms with a specific number of protons in their nuclei—known as the atomic number—are what make up a chemical element. The number of neutrons in an element's atoms can vary; atoms with different numbers of neutrons are referred to as the element's different isotopes.

Every element contains a different number of protons. The atomic number of an element is the total number of protons in all of its atoms. An atom's mass number is calculated by adding its protons and neutrons.

Answer:

A. 4s subshell.

B. An element with the valence electron configuration 2s² 2p⁵ would form a monatomic ion with a charge of -1.

In order to form this ion, the element will gain 1 electron into the 2p subshell

A) The element with 4s² configuration form a monatomic ion with a charge of  +2 and the element will lose electrons from the 4s subshell.

B) The element with 2s²2p⁴ configuration form a monatomic ion with a charge of  -2 and the element will gain electrons into the 2p subshell.

Valence electrons are the electrons occupying the outermost shell of an atom while the electrons in the inner shell are called core electrons. Lewis structures are helpful to determine the number of valence electrons and knowing the types of bonds.

Valence electrons are filled in different shells and these electrons are caused interaction between atoms and lead to the formation of chemical bonds.

Only electrons present in the outermost shell can contribute to the formation of a chemical bond or a molecule and decide the reactivity of the element.

The element with a 4s² configuration forms a monatomic ion as it loses both electrons present in the 4s subshell.  This will lead to a charge of  +2 on the element and the element from a monoatomic ion with +2 charge.

The element with 2s²2p⁴ configuration will accept two electrons into the 2p subshell. So that it can get the nearest noble gas configuration and it will form a monoatomic ion with -2 charge.

Simple diffusion: a process in which the substance moves through a semipermeable membrane or in a solution without any help from transport proteins.

Facilitated diffusion: is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.

Osmosis: Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.

Vesicular transport: is the predominant mechanism for exchange of proteins and lipids between membrane-bound organelles in eukaryotic cells.

Phagocytosis: is a cellular process for ingesting and eliminating particles larger than 0.5 μm in diameter, including microorganisms, foreign substances, and apoptotic cells.

Pinocytosis: the ingestion of liquid into a cell by the budding of small vesicles from the cell membrane.

Exocytosis: a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.

Active transport:the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
