Acid Rain is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone ( SO, NOx, and O ) is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( Acid Rain, Acid Snow, Acid Hail, Acid Sleet ). When the chemicals arent absorbed into clouds, they can drift […]

Additionally, the background of the survey is provided, indicating that students in various areas of Dasmarinas are facing difficulties in […]
Introduction: The dissociation invariables of weak monoprotic acids were determined with the assistance of a buffer and pH metre. Experiment: This experiment was performed harmonizing to the processs as provided in the Chemistry 111B research lab manual: Po. Henry and Senozan. N. “General Chemistry Experiments Chemistry 111B”. 8th Ed. 2004 Hayden-McNeil Publishing. pp 80-88. To […]
Acid Rain is a term frequently heard in the news and holds significant importance for Earth’s ecosystem. It refers to rainfall that has a higher acidity level compared to normal rainfall due to excessive acid content. The issue of acid rain is complex and stems from air pollution, impacting various aspects such as weather, chemistry, […]
INTRODUCTION Imagine going fishing on a cool Autumn day, the trees are all different shades of orange, brown and red and the birds are singing their beautiful songs, but their is a serious problem because when you arrive at the river all plant and animal life are gone. This is by no means a recent […]
pH is the measurement of acidity or alkalinity in the blood. It ranges from 1 to 14, with a pH of 1 indicating extreme acidity and a pH of 14 indicating extreme alkalinity. The optimal blood pH level is approximately 7.4. When the pH falls below 7, it results in excessive acidity which disrupts metabolism […]
In the 1960s and 1970s, microscopists had to rely on textile dyes for staining as there was a limited supply of specific dyes available. These textile dyes were crude and inconsistent in composition. Plant-based dyes like wood, indigo, saffron, and madder played an important role in the economies of Asia and Europe. Resist dyeing techniques […]
Introduction The fundamental components of all living beings are cells. Cells offer structural support, absorb nutrients, and convert energy. They also possess specific functions and genetic material for replication. Furthermore, cells function as metabolic compartments where a variety of chemical reactions occur. There are two categories of cells: eukaryotic and prokaryotic. Both prokaryotic and eukaryotic […]
How does the ph level of water affect its rate of evaporation? Examples: Almost not all in any normal range of pH values because changing pH has little effect on the total solids dissolved in the water. However, at very high or very low pH levels, say 12 you will see an effect from the […]
Concepts/Application: Writing chemical formulas, writing ionic equations, determining solubility, measuring acidity and basilica. Pre-Lab Discussion A salt is an ionic compound containing positive ions other than H+ and negative ions other than OH-. Most salts will dissociate to some degree when placed in water. In many cases, ions from the salt will react with water […]
“To evaluate the pH level of Acme wastewater and proceed with testing and treatment, it is crucial to assess its health.” Additionally, we must check for copper presence in the water. If copper is detected, we must go through the necessary protocol. In the case of turbidity, we must find a solution to clarify and […]
How do honey (strained honey), aloe vera, urine, and saliva affect the respiration rate of Saccharomyces cerevisiae? Background Information China is one of the states with the longest period of history. Beginning with the Shang Dynasty till present, China has been creating and inventing numerous materials including paper, gunpowder, and the compass among others. The […]
‘Enzymes are special kinds of proteins that are found in all living matter. Living cells need enzymes to live and grow. Enzymes are catalysts, substances which speed up chemical reactions present in very small amounts without being changed in the reaction’ [1] .It was firstly named enzyme by a German physiologist, Wilhelm K�hne in 1878. […]
Salivary amylase, found in humans, is enzyme that catalyzes the hydrolysis of starch into simpler compounds. Its enzymatic activity is affected by several factors, such as temperature and pH. The rates of enzymatic activity of salivary amylase in different temperatures and pH were measured and resulted to be very near 50 C and 7 respectively. […]
The digestion of starch begins in the mouth, where it is mixed with saliva containing the enzyme salivary amylase, or Ptyalin. Starch, a long chain of repeating glucose subunits, is hydrolyzed first into shorter polysaccharide chains this is used as a continual mechanism to help the removal of good debris from the gingiva but has […]
Enzymes have enormous potential in the commercial world. Since they can catalyse specific reactions at relatively low temperatures, they are more versitale and cheaper than inorganic cataylstys. Enzymes can work out a range of Ph levels and normal atmospheric pressure therefore energy saving. Enzymes are biogradable and therefore cause less environmental pollution.Enzymes are formed from […]
Introduction Bioinformatics is a field within biology that focuses on the storage, retrieval, and analysis of biological data. It includes various types of information, such as nucleic acids (DNA/RNA), protein sequences, structures, functions, pathways, and genetic interactions. The discipline is vital due to its ability to handle extensive knowledge about biomolecules that surpasses human capabilities […]
