Why you are adding marble chips during heating?
Marble chips are added during heating so that the solution or substance can boil evenly. Evenly boiling the solution will cause it not to have heating spots, which can cause an eruption of bubbles. Heating spots are caused when the heat being applied is only getting to the liquid at the bottom of the flask, causing the liquid down there to evaporate more quickly than the upper liquid. The liquid evaporating causes bubbles to shoot through the solution vigorously, disrupting the system. To avoid these heating spots, we add marble chips or boiling chips to induce a nice, even boil.
What is observed when heating Fe and S?
When heating iron (Fe) and sulfur (S) together, a chemical reaction occurs to form iron sulfide (FeS). This reaction is exothermic and produces a black solid product. The iron sulfide formed can be observed as a black solid residue after the reaction is completed.
Acid is added to a beaker containing crushed marble what effect does the stirring this mixture have on the system?
When acid is added to crushed marble, a chemical reaction occurs between the acid and calcium carbonate in the marble, producing carbon dioxide gas, water, and a salt. Stirring the mixture enhances the reaction by increasing the contact between the acid and the marble particles, allowing for more effective dissolution and gas release. This agitation accelerates the reaction rate, leading to a quicker production of bubbles and more vigorous effervescence. Overall, stirring facilitates a more uniform and rapid reaction within the system.
How long does it take for a lump of marble to produce 20ml of gas?
The time it takes for a lump of marble to produce 20ml of gas can vary depending on factors such as the size of the marble, temperature, and the reaction taking place. In a chemical reaction like the reaction between marble (calcium carbonate) and acid (such as hydrochloric acid), gas is produced. The rate of gas production can be affected by the concentration of the acid, temperature, and the surface area of the marble.
How is quick lime prepared from marble with reaction?
Quick lime or burnt lime is chemically known as Calcium oxide (CaO)It can be prepared by 'burning' or heating marble or limestone to above 825 °C, that contain calcium carbonate (CaCO3; mineral calcite) in a lime kiln.CaCO3 --> CaO + CO2(gas)
Is corrosion of marble is a chemical or physical change?
Corrosion of marble is a chemical change. It occurs when the minerals in the marble undergo a chemical reaction with substances like acids or salts, leading to the deterioration of the marble's structure.
What reaction occurs when salts are heated?
By heating salts can be dehydrated, thermally decomposed or melted.
What happens when marble is put into vinegar?
The carbonates in marble will react with the acid in vinegar in the reaction: acid + carbonate = water + salt + carbon dioxide. Thus, the volume of vinegar will decrease, the volume of the marble will also decrease, a salt will be produced, and effervescence occurs (bubbles are formed). To test the gas in the bubbles produced, pass it through aqueous calcium hydroxide (limewater). A white precipitate will be formed in the limewater shortly.

What gas bubbles out when drops of hydrochloric acid are dropped on marble?
Carbon dioxide gas bubbles out when drops of hydrochloric acid are dropped on marble. This reaction occurs because the hydrochloric acid reacts with the calcium carbonate in the marble, producing carbon dioxide gas as a byproduct.

When heating iron (Fe) and sulfur (S) together, a chemical reaction occurs to form iron sulfide (FeS). This reaction is exothermic and produces a black solid product. The iron sulfide formed can be observed as a black solid residue after the reaction is completed.
What is the chemical reaction of marble and lemon juice?
there is no chemicle reaction
What will happen if you put marble in hydrochloric acid?
Marble is made out of mostly carbonates. When any acid, including hydrochloric acid, is added to a carbonate, carbon dioxide will form. The acid may bubble as the reaction takes place, and some or all of the marble will be destroyed.
What three compounds are best for melting marble?
Marble CaCO3 can not be melted it becomes decomposed on heating, in to CaO and CO2.
The rate of reaction between hcl and marble chips?
The rate of reaction between HCl and marble chips is dependent on factors such as the concentration of the acid, the surface area of the marble chips, and the temperature of the reaction. As the concentration of the acid increases, the rate of reaction also increases due to more collisions between the acid molecules and the marble chips. Similarly, a higher temperature increases the kinetic energy of the particles, leading to more collisions and a faster reaction rate. The surface area of the marble chips affects the rate of reaction by providing more sites for acid molecules to react with, which speeds up the reaction.
Is testing stones with acid to see if they are marble a chemical change?
No, testing stones with acid to see if they are marble is a physical change. The acid reacts with the marble to produce a fizzing or bubbling reaction, indicating the presence of calcium carbonate in the marble. This reaction does not change the fundamental chemical composition of the marble.
