Bonding Reports Samples For Students

Abstract

Materials exhibit different chemical and mechanical properties such as strength and durability. Combining different materials to form a material composite enhances their individual properties in different measures. In this experiment, the mechanical strength of composite sandwich structures was investigated through bending. Four samples were investigated for their properties on bending and strength. Three of the four polystyrene beams were reinforced with paper while the fourth beam was investigated without paper reinforcement. One of the beams was bonded with construction paper on one side; the next bema was bonded with construction paper on both sides while the third beam was ...

Introduction

Reduction reactions are very important in chemistry as they are effective processes for synthesizing new compounds from existing ones. In organic chemistry, a compound is said to be reduced if it acquires new hydrogen. There are diverse reagents for carrying our reduction reactions. Two of these are sodium borohydride (NaBH4) and lithium aluminum hydride (LiAlH4) - the latter is a more powerful reducing agent compared to the former.
In this experiment, NaBH4 was used to reduce p-Nitrobenzaldehyde to form p-Nitrobenzyl alcohol. NaBH4was used over LiAlH4 in this experiment, because LiAlH4 would also reduce the nitro group of the aldehyde.

Executive Summary

Video gamers have been with the society for a while, and they are associated with certain positive implications for individuals who play them. Video games enhance social skills since they can be used as a bonding activity and people interact over the internet when playing video games. Video games also improve social confidence which improves social interactions between individuals. Learning of subjects such as mathematics can also be enhanced by playing video games. Soldiers, surgeons and pilots can also improve their performance at work by engaging in video games. Management skills such as strategic management, planning and decision making ...

Hai Di Lao Hot Pot Strategy
Background
Hai Di Lao Hot Pot is a chain of restaurants established in Cihina in 1994 and is now spread across China, South Korea, Singapore and the USA (Haidilao 2016). As the name suggests, its specialty is the Chinese Sichuan hot pot, a dish in which the ingredients are assembled together and are cooked in a hot pot at the table of the diner. The humble beginnings, ...

Thermal conductivity is defined as a material’s property to conduct heat. Heat transfer across materials occurs in materials that have lower thermal conductivity and transfers faster in materials with high conductivity. It is important to determine the thermal conductivity of materials since different materials are used for different applications. For instance, materials with high conductivity are more efficient when they are used as heat sinks since they can conduct heat away faster. Those with lower thermal conductivity are often used as insulators (Callister 78).
The classical transfer of energy happens through conduction, radiation, convection or combination of all ...

Abstract

Concrete acts as one of the most essential and cost-effective construction material made from a mixture of sand, cement, aggregates, and water. Cement acts as a binder for holding all the components together. Engineers working in the construction site must understand the purpose of the construction because different structures require different concrete strengths. The strength of cement paste used controls the overall strength of concrete that depends on the water-cement ratio. The following experiment was conducted to investigate different mechanical and physical properties of concrete.

Objective: To determine mechanical properties of concrete.

Materials used: Aggregate (coarse and fine), sand, cement, water, compressive machine, cylindrical and rectangular molds, timer, ...

Abstract

Scientists have conducted multiple ab initio calculations to determine the infrared spectra and the array of complexes BrH: NH3, ClH: NH3 and FH: NH3. Additionally, the research incorporates investigating the effects of inert gasses’ atoms on the infrared spectra and arrangements. The scientists constructed a double dimension MP2/6-31+G (d, p) energy surface for complexes XH: NH3. The two-facet Schrodinger calculations were solved for the dimer and the proton stretching series. Most complexes have differing infrared spectra even though their equilibrium arrangements are characterized by traditional hydrogen bonds. The grounds (v=0) and (v=1) that are both found in FH.NH3 describe the ...

Community projects aim at making the community a sustainable place for each and every individual. The community project on focus is the Australian Football league that partners with administrators and community volunteers association in support of the differently abled children. AFL program shares a sense of companionship and belonging to the disabled children integrating them and making them feel important as other members of the community (KIM, EHRICH & FICORILL 2012). Similarly, with the help of the Adult Migrant English program, the Australian Football league program for the disabled children have been offering learning, social and recreational opportunities to the children, organizations ...

The main aim of the experiment is to prepare cyclohexanol by an acid catalyzed reaction of hydrocarbon compound like cyclohexene. Water is majorly used as a solvent in the experiment and with this, it is believed to be the highest in ratio when considering the nucleophile that attracts the carbon compounds.
- For cyclohexeneC6H10, the mass = 8.5g;
Molar mass is =82.143g/mol
Moles of cyclohexene =mass of the cyclohexene measured (g)molar mass of the cyclohexene
