The empirical formula of benzene is CH. Its molecular weight is 78.1 amu.
To determine the molecular formula, we divide the molecular weight by the empirical formula weight:
Molecular weight = 78.1 amu
Empirical formula weight = 13.02 amu
78.1 amu / 13.02 amu = 6
Therefore, the molecular formula of benzene is C6H6.
Pore engeneering of ZSM-5 by silylation for the side chain alkylation of toluneDr. VIJAYKUMAR MARAKATTI
A novel silylated ZSM-5 zeolite was synthesized for the methylation of toluene to produce p-xylene. The zeolite was characterized and tested as a catalyst for toluene methylation. The zeolite was modified through silylation to tune its shape selectivity. Testing showed the silylated zeolite with a SiO2/Al2O3 ratio of 187 had high p-xylene selectivity of over 90% for toluene conversion. Process parameters like temperature, pressure and water presence were optimized to improve catalyst stability and selectivity.
Modification & Application of Borate Zirconia CatalystRanjeet Kumar
Solid catalysts are of great advantages in alkylation reaction due to heterogenous reaction which makes separation of catalysts very easy and environment friendly. Here, sulfated and borate zirconia catalysts are used to search for ortho-xylene with Toluene & methanol. To find a new path to get o-xylene, catalysts surface was studied and a new mesoporous borate zirconia catalyst was prepared. Mesoporous Borate Zirconia had showed a very efficient path to manufature o-xylene.
The document discusses sulfated zirconia as a solid acid catalyst. It describes the synthesis of sulfated zirconia through precipitation and impregnation methods.

This document summarizes research on producing activated carbon from waste tea using potassium carbonate (K2CO3) as the activating agent. The objectives were to use waste tea as a raw material and determine how process parameters influence the activated carbon characteristics. Waste tea was carbonized at different temperatures and times, with varying K2CO3 amounts and impregnation periods. Testing showed that the surface area, yield, micropore and mesopore volumes depended on the carbonization conditions and K2CO3 levels. Micropores predominantly formed between 500-800°C, while mesopores increased at 900°C. Waste tea proved a potential low-cost source for high surface area, porous activated carbon.
The document provides instructions for candidates taking the CBSE Board Examination for 2012-2013. It states that the code number on the question paper should be written on the answer book title page. It also notes that the paper contains 30 questions and candidates should write the serial number before attempting each question. Finally, it provides time allotments for reading the paper and starting the exam.
This document summarizes a CFD study on fluidized bed pyrolyzers. The study used two models: 1) a particle pyrolysis model to simulate wood pyrolysis kinetics and heat transfer, and 2) a reactor model in ANSYS FLUENT to model secondary reactions in a fluidized bed. The models examined the effects of feedstock size, fluidized gas temperature, and vapor residence time on liquid fraction yield. The results showed that fluidized gas temperature has a more critical impact than residence time on secondary reactions. Downward vapor flow along the reactor wall was also observed and should be considered in design. The models provide insights into reducing secondary reactions to maximize liquid yield in fluidized bed pyrolysis.
1) The document discusses using the DayCent ecosystem model to estimate greenhouse gas emissions from Irish grasslands and soils.
2) Parameterization of DayCent was done based on a long-term dataset from Northern Ireland to simulate biomass production, soil carbon, water content, and greenhouse gas fluxes.
3) While DayCent captures key processes in mineral soils, it does not adequately simulate organic soils like peatlands. Further improvements would be needed to apply it reliably across all Irish soils.

The document summarizes the history and development of oral rehydration solution (ORS) for treating diarrhea and dehydration. It describes how early analyses of stool and extracellular fluid compositions led to the combination of glucose and sodium in ORS. Further refinements included adding potassium to address hypokalemia and citrate to correct acidosis. ORS was optimized through the World Health Organization with adjustments to glucose, sodium, and chloride concentrations. Additional developments comprised rice-based ORS, zinc supplementation, and home-made alternatives using foods like breastmilk or rice porridge. Severe cases still require intravenous fluids.
A solution is a mixture of two or more substances, with a solvent dissolving a solute. Water is an example of a common solvent that can dissolve soluble solutes like sugar, salt, and coffee. There are two types of solutes - soluble substances that can dissolve in water, and insoluble substances that cannot dissolve in water and remain as particles, like sand, paper, oil, and rubber. Students are assigned to make a list of at least 10 soluble and 10 insoluble substances found in their house.
This document provides information on various isolated tissue preparations that can be used to study the effects of drugs. It discusses the advantages of different in vitro, ex vivo, and in vivo preparations using tissues from animals like guinea pigs, rabbits, rats, mice, cats, and dogs. Specific tissues that are mentioned include isolated strips of intestine, trachea, atria, fundus, vas deferens, anococcygeus, and more. The document outlines the process for setting up these preparations in an organ bath, applying drugs, and measuring responses. It also lists the typical drugs that different tissues are sensitive to and the receptors involved.
This document discusses significant figures and how they are used in science. It defines significant figures as the digits in a measurement that are known with certainty. Measurements are approximate numbers, while amounts of money are exact numbers. When recording measurements, only digits that are dependable based on the precision of the measuring tool are written down. The number of significant figures is determined by counting all digits starting from the first non-zero digit, with some exceptions for trailing zeros. Calculations with measurements require rules for rounding based on the least precise term to determine the number of significant figures in the final answer.
This document discusses oral rehydration salts (ORS) and oral rehydration therapy (ORT) for treating dehydration caused by diarrhea. It notes that diarrhea is a major cause of death worldwide, especially in children, but that most of these deaths can be prevented through fluid replacement with ORS. The document describes the composition and use of ORS, including how glucose and sodium in ORS help rehydrate patients by promoting water absorption in the intestines. It outlines the history and development of ORS, from early practices to the current WHO-recommended reduced osmolarity formula. The widespread use of ORS and ORT programs has significantly reduced mortality from diarrhea.
Este documento describe los métodos para caracterizar el carbón mineral mediante ensayos de análisis inmediato. Estos ensayos determinan parámetros como la humedad, cenizas, materias volátiles y carbono fijo.

El objetivo es proporcionar información sobre la composición química del carbón y su comportamiento durante procesos como la combustión o carbonización.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise boosts blood flow and levels of neurotransmitters and endorphins which elevate and stabilize mood.
Oral rehydration therapy (ORT) involves rehydrating a dehydrated person through oral intake and corrects water and electrolyte deficits. ORT has been shown to effectively treat 90-95% of cases of cholera and acute diarrhea. The principle behind ORT is that glucose enhances intestinal absorption of salt and water when taken orally, correcting electrolyte and water deficits. Reduced osmolarity ORS is the most effective type, decreasing stool output and need for IV therapy in children with non-cholera diarrhea. ORT is a low-cost treatment that can be administered at home using readily available ingredients. It has significantly reduced mortality from cholera and diarrhea globally.
This document discusses significant figures and how to determine the number of significant figures in a value. It explains that significant figures are used for estimated or rounded values, not exact values like monetary amounts. The key points made are:
- Significant figures can be determined by writing the number in scientific notation. The number of digits in the mantissa is the number of significant figures.
- For numbers greater than 1, the power of 10 will be positive. For numbers between 0 and 1, the power of 10 will be negative.
- Moving the decimal and dropping unnecessary zeros converts the number to a form to count significant figures. Trailing zeros after a decimal are always significant.
- Examples are provided to demonstrate
This document discusses significant figures and measurement uncertainty. It provides examples of exact vs measured numbers, rules for determining significant figures, and how to properly round measurements. Key points include:
- Measured numbers have uncertainty since the last digit is an estimate
- There are 4 rules for determining if a zero is significant
- Scientific notation makes it clear how many digits are significant
- Calculations should be rounded according to whether the first discarded digit is less than or greater than 5.
1) The document introduces the concept of significant figures through an imaginary scenario of students trying to get into a dance club called "Club Significance".
2) It explains the four main rules of significant figures: numbers that are non-zero are significant, zeros between non-zero numbers are significant, numbers after a decimal point are significant, and numbers to the left of the multiplication sign in scientific notation are significant.
3) The students work through examples to understand each rule and then try arranging themselves according to the rules to get into the club.
