acid to produce 1 mol of barium sulfate and 2 mol of water. In the reactants, it is indicated that there is a 1:1 molar ratio, which is the first indication of what will be produced in the reaction. Also, since barium hydroxide is a strong base and sulfuric acid is a strong acid, the reactants neutralize each other and the products produced are insoluble3. The point in the reaction at which the reactants neutralize each other is the titration's end point, which can be seen in all the figures as well
Are Women in China Weak or Strong? For years, it has been debated on whether or not women in China were weak or strong. In China, women were regarded as the lesser gender. Yet, does that necessarily mean that women in China are weak? There are facts supporting both opinions, but I believe there are more signs pointing towards how resilient and strong women actually are. Women in China were exceptionally strong despite being persecuted for their gender; Although these women were required by tradition
it.) I believe that the passion I am developing for working with computers and software can very easily grow into something to the same magnitude as that as I have for music. This scholarship would help fund that passion so that it can grow into a strong force in my
now have to choose the appropriate compounds in order to make sure that the experiment is carried out in the appropriate manner. I will now display a table containing the different compunds for my availability: Strong acid Weak acid Strong alkali Weak alkali Hydrochloric acid Ethanoic acid Sodium Hydroxide Ammonia solution Nitric acid Ethandioic acid Potassium Hydroxide Sodium Catbonate Sulphuric acid
by measuring the rate, the amount of time the reaction takes will be measured. Hydrochloric acid is a stronger acid that is found in digestive juices in the human stomach and is also used for cleaning metals before they are coated. When you mix a strong acid like HCl with any carbonate you will have a chemical reaction in which CO2 gas is released. This means that it will fizz indicating a chemical reaction. These two elements can react with hydrochloric acid to yield carbon dioxide, calcium chloride
The science of Star Wars is book written by Jeanne Cavelos, it tries to link the content of the Star Wars trilogies with modern science. It offers the readers the plausibility of the phenomena that occurs in the world of Star Wars. The book is divided into five chapters excluding the introduction. She proceeds from environments to aliens and androids to spaceships and weapons to end with a chapter on “The Force”. The first Chapter is called Planetary Environments. It has four essays and seven section
Nowadays, organizations is facing rapid change to the business environment where it becomes more complex than it were before. Indeed, these situation means that businesses need to find strategy to analyzing the implications of these changes and modifying the organizations reaction itself towards these situation. The strategies that the organization will apply also require gaining a complete understanding of the external environment of the organization. While understanding the macro-environment of
is an environmental phenomena. It is composed of sulfuric acid and nitric acid, in addition to water, which come to be due to the interactions between the water and atmospheric pollutants, such as sulfur oxide and nitric oxide. This combination of strong acids in water is known to be detrimental to the environment, infrastructure, and the health of people. Due to the water cycle, other water bodies, such as lakes and streams, are affected by the excess acid in rain in that their aquatic populations
the novel, the relationship between Lena and Ying-Ying is represented as weak and distant. These characters are prevented from having a healthy relationship because they do not support each other, they possess similar characteristics, and they are strong. The weak and distant mother-daughter relationship is formed by many factors, including lack of support. The lack of
stronger the acid, the larger will its Ka value be. However, Ka values are very small and often require dealing with negative exponents, which is why it is sensible to use pKa values for convenience. Weak acids tend to have higher pKa values compared to strong acids. The average pKa value (16.68) for the first ten alcohols is about 12 units higher than that of the carboxylic acids (4.74). These pKa values suggest that alcohols are barely acidic, as their pKa is lower than that of water (14.00), whilst carboxylic
