The majority of bullets are composed of toxic lead. Lead bullet fragments can dissolve when they come into contact with bodily fluids.

The following is the reaction’s balanced chemical equation.

2 C4H10 + 13 O2 => 8 CO2 + 10 H2O

First, to create a chemical equation for any hydrocarbon that is balanced:

1. The number of carbon atoms in the hydrocarbon is equal to the number of moles of carbon dioxide.

2. Half as many moles of water as there are hydrogen atoms in the hydrocarbon.

3. Then, until the amount of oxygen on both sides of the equation is equal, add oxygen to the reactant side.

In the Friedel-Craft reaction, AlCl3 (anhydrous) serves to create an electrophile that subsequently contributes to the benzene nucleus. When arenes react with acyl chlorides or anhydrides, monoacetylated products can be produced thanks to this electrophilic aromatic substitution. The products don’t go through a second substitution; they are deactivated. For both the substrate and the product to form complexes, a stoichiometric quantity of the Lewis acid catalyst is typically needed.

When an amino group and a carboxyl group combine, a dipolar ion known as a zwitterion is created. Consequently, an amino acid makes up the majority of it. In a zwitterion, the amine group has a positive charge and the carboxyl group has a negative charge. A hydrogen ion is internally transferred from the -COOH group to the -NH2 group, leaving behind an ion that is both positively and negatively charged. We refer to this as a zwitterion. Even in the solid state, amino acids exist in this form.

Since the ratios of its atoms cannot be simplified, E.F. and M.F. are equal.

The boiling point will rise as the strength of the intermolecular forces increases because more energy is needed to overcome them.

A force that operates between the various polar ends of molecules is known as a dipole-dipole force. Between two distinct polar ends of molecules, hydrogen and chlorine experience a dipole-dipole force. Another HCl molecule’s relatively negative end will be drawn to the comparatively positive end of a polar molecule. Option A is therefore the right choice.

The cationic radius of positively charged ions would decrease as the effective nuclear charge increased. The ionic radius decreases as a result of the electrons being drawn closer by the nucleus’s stronger attraction.

Option D is the right one. This is so because Be is a member of Group IIA and Li is a member of Group IA. Be is smaller than Li because, as we know, the atomic radius decreases with time.

Acetaldehyde gains an oxygen atom during oxidation, which is the process by which aldehyde changes into carboxylic acid.

As stated in option C, intermolecular forces at the molecule’s surface tend to hold the surface molecules close together, preventing collisions, which results in surface tension in the liquid.

O = 40% no = 40/16 no = 2.5

M = 60 percent nM = 60/24 nM = 2.5

M : O 2.5/2.5 2.5/2.5 MO = Empirical formula

The aldehyde functional group is called formyl. The formyl functional group, or CHO, is obtained by removing the R group from an aldehyde. As a result, it is always “out of the chain” or at the end of the chain.

An iron cathode and a carbon (graphite) anode are used in the Downs cell. Magnesium chloride, heated to a liquid state, serves as the electrolyte.

The mass of a substance in grams that reacts with or is chemically equivalent to one gram of hydrogen or eight grams of oxygen is its equivalent weight.

The subshell inside a principal energy level (n) is specified by the azimuthal quantum number (l). The following describes how its values vary with the principal quantum number (n):

The values of l can range from 0 to (n-1). The values of l will range from 0 to (3-1) if n=3, making l = 0,1,2.

Therefore, the azimuthal quantum number (l) can be 0, 1, and 2 if the principal quantum number (n) is 3.

Because of its many characteristics, water is regarded as a universal solvent.
