pollution emitted by human activities‚ such as factories‚ electrical power plants and automobiles. Two main pollutants are sulfur dioxide (SO2) and nitrogen dioxide (NO2)‚ which reacts with substances in the atmosphere‚ such as water and oxygen‚ to form acid rain. While rain water has a pH of 5.6‚ acid rain has a pH of 5 or less‚ which is acidic enough to harm plant life. Due to the reactivity of acid rain‚ the cell processes of plants are disrupted‚ and the cells die or become unable to function properly

populations of six economically important species in the genus Brassica have unusual potential for resolving many problems in plant biology and for use in education. Rapid-cycling brassicas can produce up to ten generations of seed per year and serve as models for research in genetics‚ host-parasite relations‚ molecular biology‚ cell biology‚ plant biochemistry‚ population biology‚ and plant breeding.

the blueberries and the purple camote peel contain anthocyanins. These plant pigments produce definite colors in solutions of different acidity or basicity. Anthocyanins are also water soluble and have colors that are dependent upon the pH of the reacting solution. In our study‚ the researchers used a lampunaya leaf that also contains anthocyanins With the knowledge of this‚ we decided to come up with a study about lampunaya leaf extract as an acid-base indicator. There are three reasons why we conducted

VALENCY Valency can be defined as the combining capacity of an element.The electrons present in the outermostmost shell of an atom are known as valence electrons and they determine the valency.The valence electrons take part in chemical reaction and they determine the chemical properties of the elements.Let us take an example‚ Theatomic number of carbon is 6 Its configuration is =2‚4 It means valency of carbon is 4. In chemistry‚ valence‚ also known as valency or valence number‚ is the number
