Organic chemistry deals with carbon-based compounds while inorganic chemistry deals with non-carbon-based compounds.

• Organic chemistry involves the study of hydrocarbons, alcohols, carbohydrates, proteins, and nucleic acids.

• Inorganic chemistry involves the study of metals, minerals, and non-carbon-based compounds like water, salts, and acids.

• Organic compounds are generally covalently bonded while inorganic compounds can...read more

Reflux ratio is the ratio of the amount of reflux to the amount of distillate in a distillation column.

• Reflux ratio is an important parameter in distillation processes.

• It is defined as the ratio of the amount of liquid returned to the column as reflux to the amount of liquid removed as distillate.

• A high reflux ratio results in a higher purity of the distillate, but also requires more energy to maintain.

• Reflux ratio can...read more

R=f/d is the formula for calculating resistance.

• R is the resistance of the material

• f is the force applied to the material

• d is the distance over which the force is applied

• The formula is commonly used in physics and engineering

• Example: calculating the resistance of a wire

A loop is a programming construct that repeats a set of instructions until a specific condition is met.

• Loops are used to automate repetitive tasks.

• There are three types of loops: for, while, and do-while.

• For loop is used when the number of iterations is known.

• While loop is used when the number of iterations is unknown.

• Do-while loop is used when the loop must execute at least once.

• Example: for(int i=0; i<10; i++) { //co

F/o and F/c are aviation terms used to refer to the first officer and flight crew respectively.

• F/o stands for first officer, who is the second-in-command of the aircraft and assists the captain in flying the plane.

• F/c stands for flight crew, which includes all the members of the crew who are responsible for the safety and comfort of the passengers.

• The first officer is also known as the co-pilot and is responsible for m...read more

Distillation column is used to separate components of a mixture based on their boiling points.

• It works on the principle of vapor-liquid equilibrium.

• The mixture is heated and vaporized in the column.

• The vapor rises and condenses at different heights based on their boiling points.

• The condensed liquid is collected in trays or plates.

• The separated components are then collected from different trays.

• It is commonly used in th

Major high risks in P2P and O2C process

• Fraudulent activities such as fake invoices and payments

• Inaccurate data entry leading to incorrect payments or deliveries

• Lack of proper controls and monitoring leading to errors and losses

• Non-compliance with regulations and policies leading to legal and financial penalties

• Cybersecurity threats such as hacking and data breaches

• Supplier or customer bankruptcy affecting the entire pr

Normality refers to the state of being normal or typical.

• Normality is a statistical concept used to describe the distribution of data.

• It is often represented by a bell-shaped curve, with the majority of data falling within one standard deviation of the mean.

• Normality is important in quality control and process improvement, as deviations from normality can indicate problems in a system.

• In chemistry, normality refers to ...read more

pH is a measure of the acidity or basicity of a solution.

• pH stands for 'potential of hydrogen'

• It is measured on a scale of 0-14

• A pH of 7 is neutral, below 7 is acidic, and above 7 is basic

• pH is important in many industries, including agriculture, medicine, and manufacturing

To prepare molar NaOH solution, dissolve the required amount of NaOH in distilled water and adjust the volume to the desired concentration.

• Calculate the required amount of NaOH using the formula: mass = molarity x volume x molecular weight

• Weigh the calculated amount of NaOH using a balance

• Dissolve the NaOH in distilled water in a volumetric flask

• Add distilled water to the flask to reach the desired volume

• Mix the soluti

Reflux ratio is the ratio of the liquid reflux to the distillate produced in a distillation column.

• It is an important parameter in distillation processes.

• It determines the efficiency of the distillation column.

• A higher reflux ratio results in a higher purity of the distillate.

• Reflux ratio can be adjusted by changing the amount of reflux liquid or the distillate flow rate.

• It is calculated as the ratio of the reflux liqu
