Highly reactive elements can be kept from reacting by holding them in containers that are made of elements that are very unreactive (or at least not reactive to the highly reactive elements they contain). Unfortunately, the 6 known stable inert elements exist at room temperature only in gas form, so do not make good containers; however, some substances such as glass are very resilient and their molecular structures tend to be stable and unreactive (which is why glass is a common material for beakers and other containers to hold a wide -- but not unlimited -- variety of chemicals).
What else can I help you with?
What are the metals kept under a paraffin?
Li (Lithium), Na (Sodium), K (potassium). They are highly reactive - they react violently with water and also react with oxygen.
Which gas in the air keeps a fire burning?
Oxygen is the gas in the air that keeps a fire burning. It helps combustion by reacting with the fuel source to produce heat and light.
How is termination differ from propagation step?
Termination is the final step in a reaction where the reactive species are consumed to produce stable products, effectively stopping the reaction. In contrast, propagation steps are where reactive species are generated and utilized to carry out the main chemical transformations in a reaction, allowing it to proceed. Termination ends the reaction, while propagation keeps it going.
What are 3 things that keeps a fire burning?
Oxygen, heat, and fuel are three essential components that keep a fire burning. Without any of these elements, a fire will not be sustained.
Table salt forms a crystal in which the elements are held together by?
Table salt forms a crystal lattice structure in which the positively charged sodium ions are attracted to the negatively charged chloride ions through ionic bonding. This strong electrostatic attraction keeps the elements held together in a stable crystal.
What are the metals kept under a paraffin?
Li (Lithium), Na (Sodium), K (potassium). They are highly reactive - they react violently with water and also react with oxygen.
Why is sodium packed in polythene?
Sodium is packed in polythene to prevent it from reacting with air or moisture, which could lead to degradation and reduced effectiveness of the substance. The polythene helps to create a barrier that keeps the sodium away from these elements, thus ensuring its stability and purity until it is ready for use.
Why is sodium kept under oil in a tightly sealed container?
Sodium is highly reactive with moisture in the air, which can produce hydrogen gas and cause the sodium to catch fire. By keeping sodium under oil in a tightly sealed container, it is protected from moisture and air, reducing the risk of it reacting and potentially causing a fire.
Which gas in the air keeps a fire burning?
Oxygen is the gas in the air that keeps a fire burning. It helps combustion by reacting with the fuel source to produce heat and light.
What is traditional police community relations?
Traditional police community relations consist of cops reacting to situations in the community. This keeps the community safe but also can take away certain rights.
Why must sodium be stored in an inert substance?
Sodium reacts vigorously with air and moisture, forming sodium hydroxide and hydrogen gas. Storing sodium in an inert substance, such as kerosene or mineral oil, helps prevent these reactions and keeps the sodium from catching fire or exploding.
What elements are in a basketball?
the basic elements in basketball is.....the stupid referee...who keeps on whistling....the weak players who keep on playing non sense..... and you..the audience who keep on asking...
Can you have cows inside Cincinnati limits?
keshav is mad tha's why he keeps goat there.
Why sodium metal kept under kerosine oil?
Sodium is a highly reactive metal that reacts violently with moisture in the air, forming sodium hydroxide and releasing hydrogen gas. Storing sodium under kerosene oil helps to prevent contact with moisture and oxygen from the air, preventing the rapid oxidation reaction. This keeps the sodium stable and prevents any potential hazards.
Does Noah Ringer ever had a girlfriend?
No not that anyone knows of. Some girl keeps claiming to be his girlfriend, but I highly doubt it. She's just doing that to get attention.
Is a soda can a chemical change?
Nope. The pressure keeps the Carbon Dioxide dissolved in the liquid, and when that pressure is relieved, the CO2 rapidly returns to its gaseous state. None of the molecules are reacting or changing, although the CO2 switches from aqueous to gaseous phase.
How is termination differ from propagation step?
Termination is the final step in a reaction where the reactive species are consumed to produce stable products, effectively stopping the reaction. In contrast, propagation steps are where reactive species are generated and utilized to carry out the main chemical transformations in a reaction, allowing it to proceed.
