1. Lewis acid/base theory defines acids as an electron-pair acceptor while a base is an electron-pair donor. The theory also explains acids and bases as either hard or soft. Hard acids/bases have ionic bonding whereby hard acids form hard metal ions. Similarly, soft acids/bases combine through covalent bonding whereby soft...

According to Boyle's law, and ideal gas contracts in volume in relation to lowering the temperature. Absolute zero is the coldest temperature that can be achieved, which would be calculated at -273.15C or -459.67F (Encyclopedia Brittanica, 2018). Nothing can be colder than this point. However, because the calculations involved in...

Hydrothermal liquefaction is a process that converts biomass materials, in the presence of water, into bio-liquid products with high energy content at a temperature of between 280-370°C .and high pressure of between 10 to 25MPa. Water acquires unique characteristics under these conditions that facilitates hydrolysis, depolymerisation and biomass decomposition to...

Abstract Two experiments were conducted to explore the solubility and reactivity of hydrocarbons. In the first experiment, an alkane was added to multiple solvents to determine solubility before and after heat was added. In the second, bromine solution was added to several alkenes to determine responses. The first experiment confirmed...
