Why is sodium carbonate soluble in water while calcium carbonate is not?
Sodium carbonate is soluble in water because it dissociates into sodium ions and carbonate ions, which are stabilized by water molecules through hydration. In contrast, calcium carbonate has a strong ionic lattice structure and low solubility due to the higher lattice energy compared to the energy released during hydration of its ions. This means that the interactions in calcium carbonate are not easily overcome by water, leading to its low solubility.
What ways are earthquakes measured?
Earthquakes are measured using seismometers that record the seismic waves produced by the shaking of the ground. The two main scales used to measure earthquakes are the Richter scale, which measures the amplitude of seismic waves, and the moment magnitude scale, which considers the total energy released by an earthquake. These scales provide a numerical value called the magnitude to quantify the earthquake's size.
What substance is produced and released by neurons in the brain?
The substance that is produced and released by neurons in the brain is a hormone called dopamine. It acts as a neurotransmitter that sends signals between nerve cells.
What substance is remaining when magnesium carbonate powder is heated Also why does the mass change Thanks?
Magnesium oxide. Carbon dioxide is released as agas.
How are strengths of earthquakes measured?
Earthquake strength is measured using the Richter scale or the moment magnitude scale. These scales quantify the amount of energy released by an earthquake. The Richter scale is based on the amplitude of seismic waves, while the moment magnitude scale considers the total energy released by the earthquake.
When calcium carbonate is heated strongly carbon dioxide gas is released CaCO3CaO CO2 what is the volume of CO2 measured stpis produced if 15.2 grams of caco3 is heated?
The molar mass of CaCO3 is 100.09 g/mol, and the molar mass of CO2 is 44.01 g/mol. By using stoichiometry, you can calculate that 15.2 grams of CaCO3 would produce 6.51 grams of CO2. Using the ideal gas law, you can then convert the mass of CO2 to volume using its molar volume at STP (22.4 L/mol). The volume of CO2 produced would be around 3.32 liters.
What gas is produced when hydrogen and calcium carbonate is mixed?
There is no reaction and thus no release of gas.
What product are formed when a metal carbonate reacts with an acid?
When a metal carbonate reacts with an acid, the products formed are a salt, carbon dioxide gas, and water. The metal from the carbonate combines with the acid to form a salt, carbon dioxide gas is released as a byproduct, and water is also produced in the reaction.
When sulfuric acid is added to calcium carbonate the gas produced?
The chemical reaction is: CaCO3 + H2SO4 = CaSO4 + CO2 + H2O Carbon dioxide is released.
What gas would you get if you mixed nitric acid and calcium carbonate produce?
If nitric acid is mixed with calcium carbonate, carbon dioxide gas would be produced along with calcium nitrate and water.
Predict the most likely products formed from the reaction between calcium carbonate and sodium metal?
The reaction between calcium carbonate and sodium metal is likely to produce calcium oxide, sodium carbonate, and carbon as products. Calcium oxide is formed from the decomposition of calcium carbonate, while sodium carbonate is formed from the reaction of sodium metal with carbon dioxide released from the decomposition of calcium carbonate. Carbon is produced as a byproduct.
Define enthalpy and how it is measured?
Enthalpy is a particular amount of heat that is produced or released at a given pressure. There are specific equations that must be used to calculate enthalpy.
Why does the mixture stop fizzing when magnesium carbonate is added to hydrochloric acid?
When magnesium carbonate is added to hydrochloric acid, a chemical reaction occurs that produces magnesium chloride, water, and carbon dioxide gas. The fizzing you see is the carbon dioxide gas being released. Once all the carbon dioxide has been produced and released, the fizzing stops.
What gas is produced when CaCO3 is heated?
When CaCO3 (calcium carbonate) is heated, it decomposes to form CaO (calcium oxide) and CO2 (carbon dioxide) gas is released.
What gas or liquid is released from copper carbonate when heated?
Carbon dioxide is released.
How is carbon dioxide released from carbonate rocks into the atmosphere?
Carbon dioxide is released from carbonate rocks into the atmosphere through processes such as weathering, dissolution, and metamorphism. When carbonate rocks are exposed to water or acidic conditions, they break down and release carbon dioxide as a byproduct. This released carbon dioxide can then be released into the atmosphere through various pathways.
Which gas is evovled on heating sodium carbonate?
Na2CO3--------Na2O + CO2 Carbon dioxide is released by the thermal decomposition of sodium carbonate.
