As populations have grown, farming practices have become more intensified to maximise crop yields and ensure we can feed the ever growing population. Fertilisers and pesticides are used on crops, and animals may be kept inside in more densely packed sheds to maximise milk yields, or egg production,
Power laws simply explained - power, base, exponents - same base - analysis. A power consists of a base and an exponent, the exponent is often written as a superscript. The power laws help you calculate. You either keep the base or the exponent. There is also a case where a power is put in brackets.
Acid and base definitions according to Brönsted are explained. At the end, protolysis reactions are described. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
The most important acids and bases are mentioned. These are very important and need to be learned. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Acid-base buffers are briefly explained, as well as the buffering effect. The main point of the screencast, however, is the pH value calculation in the buffer range. Furthermore, it is described how buffer systems are formed in titrations of weak acid with a strong base. Original: "Wolfgang Dukorn"

Learn how drip irrigation helps conserve water as compared with traditional irrigation methods in this video from the California Academy of Sciences. This resource stimulates students’ thinking about protecting this limited resource. Students can ask questions, develop a model, and make evidence-bas
An acid is a substance that will dissociate in water to give a proton (or H+ ion) and a conjugate base. An acid is considered to be strong if dissociation nears 100%, and weak if dissociation is usually less than 1%. In this lesson, we will learn about strong alkalis and weak alkalis. An alkali
The basic reaction behavior of aniline is briefly explained. Subsequently, the basicity of aniline is compared with ammonia and methylamine. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
