Abstract Food waste is a global-scale phenomenon, Food waste generated in India is huge and waste segregation methods are still inadequate and is a growing issue. With less than 55% of waste collected and less than 17% processed (Arian, 2018). Moreover, landfills are held for being the largest GHG emitters. This topic has gained popularity & momentum in recent years. This paper proposes the problems and challenges faced during the waste segregation process, decomposition of waste with different technologies, and…...

The size of this activation energy is different for different reactions. I think that the concentration of a solution affects the rate of reaction because ‘the rate of reaction depends on how frequently the molecules of the reacting substances collide. A more concentrated substance has more molecules for a given volume than a more dilute substance because there are more molecules about, the frequency of the successful collisions is greater and the reaction happens faster. ’ I have predicted this…...

This will help ensure that the results of the experiment are reliable and ensure that the acids react with the magnesium and not the formulated oxide layer. The Acids: Choice of acids and their varying strengths was based upon the Bronston-Lowry theory. According to the Nuffield Advanced Chemistry Students' Book, acids that ionise completely at moderate dilutions are called strong acids. Consequently they tend to have a large Ka (dissociation constant) value. Weak acids interact very little with water therefore…...

The value of the impure aspirin RfP compared with pure aspirin RfA, the difference between these two substances was only 0.64 - 0.58 =0.06, which was less than 0. 01. Because the Rf value of a compound was constant on the same plate in condition of the temperature and solvent were kept the same and the closer the value of RfP and RfA the possible these two substances were the same.

How to protect iron from rusting?
Words • 357
Pages • 2
To investigate the ability of metals to act as a sacrificial protector of iron, preventing or reducing rusting. Theory Iron oxide is more stable than iron metal, so when given the opportunity iron will be readily oxidised. Iron reacts with oxygen and water to form a hydrated form of iron(III) oxide (Fe2O3i?? xH2O), known as rust, which is permeable to air and water so the metal underneath the rust layer continues to corrode. The iron atoms readily give away two…...
The enthalpies of combustion

Standard enthalpy change of combustion is the energy change that occurs when 1 mol of fuel is completely burnt in oxygen under standard conditions. However, it is impossible for substances to be burnt under standard conditions. The enthalpies of combustion are different depending on the number of carbons and hydrogens in each substance. For example, the enthalpy combustion for methane is -890 kJ mol-1, however the enthalpy change of combustion for ethane or propane will be greater because more bonds…...

Lithium reacts violently with water to give off flammable hydrogen gas and corrosive dust. Lithium hydroxide (LiOH) is a corrosive alkali. Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (short-term) inhalation exposure may cause eye, nose, and respiratory tract irritation and inflammation and pulmonary oedema in humans. Acute oral exposure may cause corrosion of the mucous membranes, oesophagus, and stomach and dermal contact may produce severe burns, ulceration, and scarring in humans. Chronic (long-term) occupational exposure…...

We found that the convection current for distilled water was slightly different from the current of acid rain. On the basis of our observations, the convection current for rain water moved slightly more quickly. This was evident when the tank containing the acid rain was put onto the hot plate, and it could be seen that its convection current was faster than distilled water's. This is because it takes less time than the distilled water for the particles in acid…...
