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 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.
Is opening a can of soda a chemical reaction?
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.
Why should the endpoint be taken as the faint pink color of the indicator?
When using an indicator in a titration, the color changes happen when the titrant has reacted with all the substance of interest in the sample. As soon as the titrant isn't reacting with the sample any more, it starts reacting with the indicator, and continuing past the first hint of color will be using too much titrant, and the calculations for the concentration of the sample will be wrong. Phenolphthalein starts out pink, but will turn red as the pH keeps changing as you go further past the endpoint of the titration.
How does competition increase stability in ecosystem?
It keeps population balanced. Apex bru
What keeps the moon close to earth?
The same thing that keeps you from floating out into space. Gravity.

Why silver bromide is kept in brown bottle?
Silver bromide is a photo reactive substance, the colour of the bottle keeps light out.
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.
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.
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.
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 an atom a piece of an element?
atom - smallest piece of an element that keeps its chemical properties; compound - substance that can be broken into elements by chemical reactions
Does Jasmine Villegas have Justin Bieber's cell phone number?
If she keeps the numbers of her ex-boyfriends, yes. You'll have to ask her yourself. Though it is highly unlikely that she does.
Is opening a can of soda a chemical reaction?
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.
What element is the fuel of the Earth?
uranium decaying into lead and other elements releases large amounts of heat which keeps the earth warm and stops the core from cooling
How do you balace the following equation C6H14 and O2 to H2O and CO2?
C6h14 + 13o2 ---> 7h2o + 6co2 The website keeps making correctinos to my capitalization of the elements, but this is the balanced equation.
