Is hydrogen gas explosion endothermic or exothermic and why?
The explosion of hydrogen gas is exothermic because it releases energy in the form of heat and light. During the explosion, the chemical bonds in hydrogen gas are broken and new bonds are formed with oxygen, releasing more energy than is required to break the initial bonds.
When did Esso Longford gas explosion happen?
Esso Longford gas explosion happened on 1998-09-25.
Is a volcanic explosion a chemical reaction?
Explosions may or may not represent a chemical change. A stick of TNT going off is a chemical explosion. A compressed gas cylinder with a failing weld that blows up while being filled is a mechanical explosion. In the case of a volcano, the cause of the explosion is mechanical. We take a page from physics to answer this question. It is a buildup of pressure caused by heating of the magma (which may include gases and water) that causes the violent release of energy that we observe.
Hydrogen gas plus oxygen gas?
When hydrogen gas reacts with oxygen gas, they form water. The chemical equation for this reaction is 2H2 + O2 -> 2H2O. This reaction is exothermic, releasing a large amount of energy.
Why is it a bad idea to heat a compressed gas?
Reactive and flammable gasses become more volatile when put under pressure, as when compressed, leading to more explosive results when ignited. If it is not your intention to ignite the gas for an explosion, it would be best not to heat a compressed (thereby more powerful) gas. Heat may also increase the volatility of the gas itself and eventually could ignite the gas. For chemically unstable gases, heat can change the chemical composition of the gas itself, which can result in violent reactions, including ignition and explosion.
Hydrogen gas has made its way into many history books. What particular event invovled this particular gas?
The event was the explosion of the Hindenberg dirigible in the 1930s.
What make chemicals explode?
The cause of an explosion is a violent chemical reaction with release of gas.
If a balloon filled with hydrogen gas explodes upon contact with a spark a chemical or physical change?
The explosion of a balloon filled with hydrogen gas upon contact with a spark is a chemical change. This is because the hydrogen gas (H₂) reacts with oxygen (O₂) in the air to form water (H₂O) and release energy in the form of an explosion.
Is TNT explosion a chemical property?
No, an explosion is a physical property that results from the release of stored energy. The chemical property of TNT is its ability to undergo rapid decomposition in a highly exothermic reaction, leading to the release of gas and heat that causes the explosion.
Is hydrogen gas explosion endothermic or exothermic and why?
The explosion of hydrogen gas is exothermic because it releases energy in the form of heat and light. During the explosion, the chemical bonds in hydrogen gas are broken and new bonds are formed with oxygen, releasing more energy than is required to break the initial bonds.
How does a dynamite explosion convert chemical energy to mechanical energy?
The dynamite contains chemical energy stored in its molecular bonds. When the dynamite is ignited, a rapid chemical reaction occurs, releasing large amounts of heat and gas. This sudden increase in pressure and volume creates a powerful shockwave that produces mechanical energy, resulting in the explosion.
Is exploding a chemical change?
An explosion is the sudden release of a volume of compressed gas. The chemicals remain the same, so it is only a physical change.Note that the reaction resulting in an explosion may be a chemical change, but the resulting pressure changes are not.
What day was the wickwar gas explosion on?
The Wickwar gas explosion itself was was in the early hours of Friday 9th January
When did Cleveland East Ohio Gas explosion happen?
Cleveland East Ohio Gas explosion happened in 1944.
When did Esso Longford gas explosion happen?
Esso Longford gas explosion happened on 1998-09-25.
Can be an explosion without air?
Yes, an explosion can occur without air. Explosions are rapid chemical reactions that produce gas and heat, which can happen in a vacuum or an inert atmosphere where oxygen is absent. For example, certain chemical explosives can detonate in environments devoid of air, as they contain their own oxidizers necessary for the reaction. Thus, air is not a prerequisite for an explosion to take place.
Is something that is explosive a physical or chemical property?
Explosiveness is a chemical property because it involves the chemical reaction that results in a rapid release of gas, heat, and pressure. It is not an inherent physical property of the material itself.
