Why does crucible and its contents gain mass as a result of heating magnisium in the air?
When magnesium is heated in the air, it undergoes a chemical reaction with oxygen to form magnesium oxide. This reaction increases the total mass of the crucible and its contents due to the addition of oxygen atoms from the air. The increase in mass is a result of the combination of magnesium and oxygen to form magnesium oxide.
What else can I help you with?
Why is it extremely dangerous to put tins of food into fire or to heat them without opening the tin first?
Heating sealed cans can cause them to explode due to the built-up pressure from the expanding air and steam inside. This can result in hot contents spraying out, causing burns and injury. It is safer to always open the can before heating to allow pressure to be released.
Why is the heating of an aerosol can so dangerous?
Heating an aerosol can is dangerous because it can cause the temperature and pressure inside the can to increase rapidly. This can lead to the can exploding, releasing pressurized contents that can cause injuries or start a fire.
What do patterns of heating and cooling in the atmosphere result in?
Ocean currents. This could also apply to wind currents.
Why would glucose give positive result upon prolonged heating with seliwanoff's reagent?
Glucose gives a positive result with Seliwanoff's reagent upon prolonged heating because it is a reducing sugar that can reduce the reagent, leading to the formation of a cherry-red complex. This occurs due to the dehydration of glucose under acidic conditions, producing furfural, which then reacts with the reagent. The prolonged heating enhances this reaction, resulting in the characteristic color change indicative of a positive result.
What is the result in the heating of sugar?
the sugar melt and can be turned to candy and if melted long enough it can be turned into ice-cream and can light on fire easily
Why should you heat an uncovered crucible in a chemistry lab experiment?
Heating an uncovered crucible allows moisture to escape and prevents any pressure buildup inside the crucible, which could result in an explosion. It also ensures that any volatile substances can evaporate before the main heating begins, preventing any sudden release of gases.
What will happen if you use a crucible that is not completely dry?
Using a crucible that is not completely dry can lead to several issues during heating. The presence of moisture can cause steam to form rapidly, potentially leading to a violent reaction or splattering of the material being heated. This can result in inaccurate measurements, contamination of the sample, or even damage to the crucible itself. Therefore, it is essential to ensure that the crucible is thoroughly dried before use.
Why is a desiccator used to cool a crucible?
A desiccator is used to cool a crucible in order to prevent the absorption of moisture during the cooling process so an accurate result can be obtained
What are crucible thongs used for?
1. Thong or clipmust be use when to weight or transfer the crucible because to avoid it absorb excess moisture from hand and this situation will affect the result.
What is the uneven heating result?
wind
