... Actually the main thing is Nitric acid is strong oxidising agent . It oxidises the hydrogen formed by water.

Debadrita Mandal 4 years, 5 months ago (11525458)

-As we know that nitric acid has another name that is aqua fortis which is a highly corrosive acid. The molecular formula of nitric acid consists of one hydrogen, one nitrogen and 3 oxygen molecules. -Also, nitric acid is also a strong oxidising agent because it can oxidise other molecules by giving an oxygen molecule and reduces itself. -Now, we know that hydrogen gas consists of two atoms of hydrogen which combine when metal and water react together. -Metals such as sodium, magnesium, manganese, etc can be used to react with a cheap compound that is water to liberate the hydrogen gas. -The balanced chemical reaction is: 2Na + 2H2O → 2NaOH + 2H2 -But if we use the dilute nitric acid then it will act as an oxidising agent and react with hydrogen gas to produce water molecules. -As we can see in the chemical reaction: 2HNO3 + H2 → 2H2O + 2NO2 Therefore, due to the oxidation of hydrogen gas by dilute nitric acid, nitric acid is not used for the preparation of hydrogen gas.

Fungi create harm by spoiling food, destroying timber, and by causing diseases of crops, livestock, and humans. Fungi, mainly moulds like Penicillium and Aspergillus, spoil many stored foods. Fungi cause the majority of plant diseases, which in turn cause serious economic losses.

Conversion a mixed number 3 3/4 to a improper fraction: 3 3/4 = 3 3/4 = 3 · 4 + 3/4 = 12 + 3/4 = 15/4 To find new numerator: a) Multiply the whole number 3 by the denominator 4. Whole number 3 equally 3 * 4/4 = 12/4 b) Add the answer from previous step 12 to the numerator 3. New numerator is 12 + 3 = 15 c) Write a previous answer (new numerator 15) over the denominator 4. Three and three quarters is fifteen quarters Conversion a mixed number 2 2/5 to a improper fraction: 2 2/5 = 2 2/5 = 2 · 5 + 2/5 = 10 + 2/5 = 12/5 To find new numerator: a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/5 = 10/5 b) Add the answer from previous step 10 to the numerator 2. New numerator is 10 + 2 = 12 c) Write a previous answer (new numerator 12) over the denominator 5. Two and two fifths is twelve fifths Multiple: 15/4 * 12/5 = 15 · 12/4 · 5 = 180/20 = 9 · 20/1 · 20 = 9 Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(180, 20) = 20. In the next intermediate step, , cancel by a common factor of 20 gives 9/1. In words - fifteen quarters multiplied by twelve fifths = nine.
