What else can I help you with?
Why is water incombustable?
The bonds between the Hydrogen and Oxygen are strong and no more Oxygen can bond. (Combustion is rapid oxidation).If you separate the Hydrogen from the Oxygen (through pyrolysis for example) the mixture is explosive.A2. The hydrogen has already burnt to make water. It cannot be burnt again.
In what type of reaction do burning flames and explosion occur?
Burning flames and explosions typically occur in exothermic reactions where heat is released, such as combustion reactions. These reactions involve a rapid release of energy in the form of heat and light.
What is that gas in the reaction between hydrogen and potassium?
The gas produced in the reaction between hydrogen and potassium is hydrogen gas (H2). This reaction is highly exothermic and violent, producing a bright light and a pop sound due to the rapid formation of hydrogen gas.
Does hydrogen gas burn with a pop?
Yes, hydrogen gas burns with a pop sound when it comes into contact with oxygen to produce water vapor. This is due to the rapid combustion of hydrogen in the presence of oxygen.
What metal reacts steadily with hydrochloric acid?
Stainless steel generally reacts steadily with hydrochloric acid, producing hydrogen gas and soluble metal chlorides. This is due to the protective oxide layer on the surface of stainless steel that prevents rapid and vigorous reactions.
What assumptions of the kinetic molecular theory explains why a gas can expand to fill a container?
Rapid Motion does.
What prevents rapid changes in pH by taking up either hydrogen or hydroxide ions?
Buffers in biological systems resist rapid changes in pH by absorbing excess hydrogen or hydroxide ions. Buffers are composed of weak acids and their conjugate bases, which can neutralize added acids or bases to maintain a relatively stable pH. This helps to regulate the body's acid-base balance and maintain optimal conditions for biochemical reactions.
What is The molecular structure of Fire?
Fire is not a substance but a chemical reaction known as combustion, involving the rapid oxidation of a fuel in the presence of oxygen. The molecular structure of the reactants typically includes hydrocarbons (like wood or gasoline) and oxygen (O2). During combustion, these reactants break down and form products such as carbon dioxide (CO2), water (H2O), and various other compounds, depending on the fuel. Therefore, fire itself does not have a molecular structure, but it is the result of chemical reactions between specific molecular structures of the involved substances.
Can combustion reactions asborbs energy?
No, combustion reactions typically release energy in the form of heat and light. They are exothermic reactions that involve the rapid oxidation of a substance, usually with oxygen as the reactant.
Why sickle cell anemia called molecular disease?
Because sickle cell diseases are characterized by the rapid loss of red blood cells

If Jupiter is a gas planet why doesn't lightning make it explode?
Explosions like that are caused by rapid chemical reactions. Jupiter is made up mostly of hydrogen. For hydrogen to explode, it needs something to react with. It usually reacts with oxygen. But on Jupiter, there is no oxygen. The only other gas that exists on Jupiter in significant amounts is helium. Helium does not react with hydrogen. So without a gas to react with, the planet is safe from explosion.
What is Jupiter thought to be like beneath its cloud?
There is thought to be a molecular hydrogen layer, and a liquid metallic hydrogen layer. At high pressures, hydrogen forms a liquid metal which is a very good electrical conductor. We think this because combined with rapid rotation, a dynamo is formed, producing Jupiter's intense magnetic field. There is also thought to be a rocky core that was formed by planetesimals, which basically supplied the initial gravity to hold the gases and create a gigantic gaseous planet.

What is the name of the gas that makes a squeaky pop when lit with a spill?
The gas is called hydrogen. When hydrogen gas is lit with a spill, it produces a squeaky pop sound due to the rapid ignition and combustion of the gas.
Why is 2 Mg O2 equals 2 MgO is not a combustion reaction?
The reaction 2 Mg + O2 -> 2 MgO is indeed a combustion reaction, where magnesium (Mg) reacts with oxygen (O2) to produce magnesium oxide (MgO). Combustion reactions are characterized by rapid reactions with oxygen, resulting in the release of energy in the form of heat and light. In this case, magnesium undergoes combustion to form magnesium oxide.
