What else can I help you with?
Is oxygen a poor conductor of electricity?
Yes, oxygen is a poor conductor of electricity. Oxygen is a nonmetal element that does not readily carry electrical charge in its natural state. Only ions or charged particles in oxygen-containing compounds can conduct electricity.
What is needed to make a fire?
To make a fire, you need three main things: fuel, heat, and oxygen. Fuel can be anything that burns, like wood or paper. Heat is necessary to ignite the fuel and start the fire. Oxygen is needed to sustain the combustion process.
How do heat patches heat up?
Heat patches contain substances that react with oxygen to produce heat when exposed to air. This reaction generates heat that warms up the patch when it is removed from its packaging and exposed to the air.
Is Flammability is not one of the characteristic properties of matter true or false?
True. Flammability is a chemical property of matter. It is not a physical property of matter. When wood burns, it changes to ashes, carbon dioxide, water vapor, and other gases. After burning, it is no longer wood.
Why does the match head not ignited when it was suspended at the top of the burner?
When the match head is suspended at the top of the burner, it is not in contact with the necessary fuel (gas) and oxygen mixture required for combustion. Thus, without access to these two components, the match head will not ignite.
Which non-metal will ignite spontaneously if its exposed to oxygen?
Phosphorus
Does methane spontaneously combust?
No, methane itself does not spontaneously combust. However, in the presence of oxygen and an ignition source, such as a spark, methane can ignite and burn.
Does paper burn in space?
Yes, paper can burn in space, but it requires an external heat source and oxygen. In the vacuum of space, there is no oxygen to support combustion, so while paper can ignite if exposed to a flame or another heat source, it cannot burn spontaneously. In a controlled environment, such as a spacecraft where oxygen is present, paper can indeed catch fire and burn.
Why do the sticks ignite before logs?
If you are referring to a campfire setting, sticks will ignite before logs because they have more surface area and are therefore, exposed to more oxygen.
What does the term reacts with oxygen mean?
It means that the substance in question will readily react with oxygen. Almost everything in group 1 of the periodic table will react violently with oxygen. exp. Sodium in powder from will ignite spontaneously when exposed to oxygen.
Is oxygen 2 a metal or nonmetal?
Oxygen is a nonmetal. Oxygen 2 is a molecule composed of two oxygen atoms, and like all oxygen atoms, it is classified as a nonmetal on the periodic table.
Does hydrogen peroxide decompose spontaneously?
Yes, hydrogen peroxide can decompose spontaneously over time, especially when exposed to light or heat. This decomposition process releases oxygen gas and water as byproducts.
What element in the air is needed for coal dust to burn?
Oxygen is the element in the air that is needed for coal dust to burn. When coal dust is exposed to oxygen and heat, it can ignite and burn.
Where do you find pyrophoric scale?
Pyrophoric scale can be found on metal surfaces where they have reacted with oxygen or moisture in the air, leading to the formation of a flaky, easily-ignited layer. This scale is commonly seen on materials like iron, steel, and certain alloys exposed to high temperatures or in corrosive environments. It typically appears as a reddish-brown or black brittle layer that can ignite spontaneously when exposed to air.
Is oxygen a metal metalloid or a nonmetal?
Oxygen is nonmetal because since oxygen isn't visable it's not solid so oxygen is nonmetal.
Is phosphorus a very reactive non-metal?
Yes, very reactive, more than silicon, nitrogen and sulfur (neighbours in periodic table. But it is not the most reactive nonmetal, which is fluorine.
Do fires start spontaneously?
Fires do not typically start spontaneously. They usually require a heat source, fuel, and oxygen to ignite. However, in rare cases, spontaneous combustion can occur in materials that generate heat through chemical processes, like piles of oily rags or compost.
