write the chemical equation for the preparation of gas balloon in the market
Answers
Answer:
Brief Description:
Six balloons are filled with different gases and ignited. Different intensities of sound are emitted, with the loudest sound occurring when a hydrogen/oxygen mixture is ignited.
Purpose/Goal:
Illustrates the properties of lighter than air gases and mixtures, and provides an opportunity to show students various aspects of the scientific method.
Explanation of Experiment:
When ignited, hydrogen gas combines with oxygen gas explosively in proportions ranging from 4.1 - 71.5% hydrogen - ignition temperature is ca. 580 °C. The gaseous reaction is
2 H2(g) + O2(g) → 2 H2O(g)
This exothermic reaction yields 232 kJ/mol of water formed. The rapid release of a considerable amount of energy causes the surrounding air to expand suddenly, resulting in a sharp expolsion. When pure hydrogen is ignited, the reaction with the surrounding air is less rapid, the sound is less loud, and a significantly larger flame is produced. The comparatively mild sounds emitted when the helium balloons are ignited are caused by the rupturing of the balloons and the escape of the gas. The explosions are caused by a sudden pressure effect through the action of heat on produced or adjacent gases.
Answer:
Gas balloons always fascinate lil children. However, when you need them, you only find them being sold on the ‘unknown’ streets, during festivals, at a fair or near the beaches.
Note that the Gas balloons that are available for party and play are usually filled with Helium gas which is less expensive and safe.
