Mozart2 essays

Mozart2 essays Wolfgang Amadeus Mozart was born in Salzburg, Austria on January 27th, 1756. He was born to Leopold and Anna Maria Pertl. Leopol was a very successful composer, voilinist, and the assistant concertmaster at the Salzburg court. Mozart showed musical talent at a very young age. By age five he was composing minuets.And at age six he played before the Bavarian Elector and the Austrian Empress.His father taught him, but said teahcing Wolfgang was hard because he knew so much already. His father was also In 1763 Wolfgangs father, Leopold, took him and his sister, Maria Anna, on a concert tour of Europe. The children performed in many courts and large cities including Paris, London, and Germany. They astonished their audiences wherever they performed. In London Wolfgang wrote his first symphonies and met Johann Christian Brahm, who had a very large influence on him. In Paris Wolfgang published his first works, four sonatas for clavier with In 1768 he composed his first opera, La Finta Semplice, which was presented for the first time a year later in his home town of Salzburg. In 1769 Wolfgang and his father set out on another tour of Italy. Here Wolfgang wrote a new opera, Mitridate ri de Ponto. He also wrote two more operas for Milan, Three years later in 1772 Wolfgang was appointed concertmaster to the archbishop of Salzburg, his home town. He composed many works while he was concertmaster. But this job was not good for him and he did not get anolg with most of the people around him. So, he soon quit this job to travel to Paris with his mother and In 1777 Wolfgana and his mother, Maria Anna, went to Paris, France. While here Wolfgang composed many works including The Paris Symphony (1778). But, he could ...

Calculating pH of a Strong Acid - Chemistry Problems

Calculating pH of a Strong Acid - Chemistry Problems A strong acid is one that completely dissociates into its ions in water. This makes calculating the hydrogen ion concentration, which is the basis of pH, easier than for weak acids. Heres an example of how to determine pH of a strong acid. pH Question What is the pH of a 0.025 M solution of hydrobromic acid (HBr)? Solution to the Problem Hydrobromic Acid or HBr, is a strong acid and will dissociate completely in water to H and Br-. For every mole of HBr, there will be 1 mole of H, so the concentration of H will be the same as the concentration of HBr. Therefore, [H] 0.025 M. pH is calculated by the formula pH - log [H] To solve the problem, enter the concentration of the hydrogen ion. pH - log (0.025)pH -(-1.602)pH 1.602 Answer The pH of a 0.025 M solution of Hydrobromic Acid is 1.602. One quick check to make sure your answer is reasonable is to verify the pH is closer to 1 than to 7 (certainly not higher than this.) Acids have a low pH value. Strong acids typically range in pH from 1 to 3.
