Is there really such a thing as rain with acid in it? Yes‚ acid rain is a very real phenomenon worldwide‚ and it’s been documented since the 1800s‚ as the Industrial Revolution caused the burning of fossil fuels like coal‚ gas and oil. When these fuels or any other organic material like wood or paper are burned‚ they release compounds like sulfur dioxide (SO2) and nitrous oxides (NOx) into the air. Are SO2 and NOx the causes of acid rain? Indirectly‚ yes. When SO2 and NOx enter the atmosphere

Separating the components of a Ternary Mixture Introduction Mixtures are usually content of two or more substances. There are two kind of mixtures‚ Homogeneous and heterogeneous mixtures. For Homogeneous mixture we cannot see the individual particles of the components‚ a good example of that will be air‚ cola drink‚ and rubbing alcohol. And for heterogeneous mixture we can see the individual particles of the components‚ a good example of that will be rocks and soil. There are a variety of methods

Benzoic Acid ABSTRACT The recrystallization of Benzoic Acid was performed to fully master the ability to purify a solid compound. This form of purification technique is especially important in chemical identification‚ where the melting point of the compound is taken to confirm its purity. In order to perform recrystallization a solubility test much be completed. Four solvents (95% Ethanol‚ Petroleum Ether‚ Acetone and distilled water) were used to identify which one is an ideal solvent. An ideal

much weaker. Besides strength of the brew‚ growing conditions‚ processing techniques- and other variables also affect caffeine content. Certain types of tea may contain somewhat more caffeine than other teas. II. Methodology Firstly‚ the extraction must be considered. Three tea bags were opened and the combined weights of the tea leaves were taken. Recording the weight is necessary. The tea leaves were returned in the bags. The next step was boiling of the tea bags in 100 mL distilled water
