Question: How many of the following metals are stored in kerosene oil?

Metals such as potassium and sodium react so vigorously that they catch fire if kept in the open. Hence, to protect them and to prevent accidental fires, they are kept immersed in kerosene oil.

Which of the following metal is stored in kerosene oil?

Sodium is stored in kerosene as it is a highly reactive metal.

Is iron stored in kerosene?

Hence, the correct answer is Option (A). Note: You must be wondering why we choose kerosene among all the substances available to us. This is simply because kerosene is a hydrocarbon that is extremely hydrophobic hence it does not let the metal come in contact with moisture or air.

Which metal is stored in oil?

Metallic sodium is usually stored in mineral oil or some other hydrocarbon, because it will react with the moisture in the air to form sodium hydroxide.

Which of the following metal is stored in kerosene a sodium B magnesium C phosphorus D Zinc?

( c) Sodium is the correct answer.

Which is preserved in kerosene?

Metal which are preserved in kerosene – Sodium, Lithium and Potassium. Lustrous coloured non-metal – Iodine and Diamond . They have a slight metallic lustre. Metal which can melt while kept on palm are – Gallium & Caesium.

IMPORTANT TO KNOW:  Do big oil companies pay taxes?

Is calcium stored in kerosene?

Calcium is stored in kerosene.

Why Sulphur is kept in kerosene?

It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide which is a highly exothermic reaction.

Is phosphorus stored in kerosene?

Phosphorus is a very reactive non-metal. It catches fire if exposed to air. … White Phosphorus is stored under water and not kerosene. It is kept submerged in water because it is a highly reactive metal and when it is exposed to air it autoignition as its ignition temperature is low.

Which non metal is stored in kerosene?

Lithium, Sodium and Potassium are stored in kerosene because they are highly electropositive and they react with water and atmospheric oxygen violently.

Why sodium potassium are stored under oil?

Sodium, potassium, and lithium are stored under oil because metals like sodium and potassium react so, vigorously that they catch fire if kept in the open. Hence, to protect them they are kept immersed in kerosene oil.

Why is lithium kept under kerosene oil Class 11?

Alkali metals are sensitive or we can say very reactive to the air and water. They are so reactive that the reaction is sometimes explosive. … Alkali metal forms oxides in presence of oxygen. Therefore, due to the high reactivity of alkali metals towards air and moisture, they are stored in kerosene oil.
