Why is the mass of KCl recovered less than the starting mass of KHCO3?
The mass of KCl recovered is less than the starting mass of KHCO3 because during the reaction that converts KHCO3 to KCl, carbon dioxide (CO2) and water (H2O) are released as byproducts. This loss of gas and water contributes to the decrease in mass. Additionally, any experimental losses during the transfer or handling of materials can further reduce the recovered mass of KCl.
Why is the mass of KCl recovered less than the starting mass HHCO3?
The mass of KCl recovered is less than the starting mass of HCO3 due to the loss of carbon dioxide (CO2) during the reaction. When HCO3 decomposes or reacts, it releases CO2 gas, which escapes into the atmosphere, resulting in a lower mass of the solid product, KCl. Additionally, any experimental losses during transfer or measurement could contribute to the difference in mass.
What is the principal stating that matter is not created or destroyed during a chemical reaction?
The Law of Conservation of Matter dictates that the mass of the reactants is equal to the mass of the products, i.e., mass will not be created, nor destroyed during the chemical reaction.
When 125 grams of solution was evaporated to dryness. 14.3 grams of solute was recovered what was the percentage of the solute?
The percentage of solute in the solution is calculated by dividing the mass of the solute recovered (14.3g) by the initial mass of the solution (125g) and then multiplying by 100. Percentage of solute = (14.3g / 125g) * 100 = 11.44%, or approximately 11.4%.
The mass of an atom aftre it under goes fission or fusion?
The mass of an atom after undergoing fission or fusion will be less than the original mass because some of the mass is converted into energy according to Einstein's mass-energy equivalence (E=mc^2). In fission, the total mass of the products is less than the original atom due to the release of energy. In fusion, the combined mass of the reactants will be slightly more than the mass of the resulting atom due to the energy input required.
Why is the mass of KCL recovered less the starting mass of KHCO3?
The mass of KCl recovered is less than the starting mass of KHCO3 because during the chemical reaction between KHCO3 and HCl to form KCl, CO2 gas is evolved. Some of the starting mass of KHCO3 is lost as gas during the reaction, leading to a lower mass of the end product (KCl) compared to the original mass of KHCO3.
Why is the mass of KCl recovered less than the starting mass of KHCO3?
The mass of KCl recovered is less than the starting mass of KHCO3 because during the reaction that converts KHCO3 to KCl, carbon dioxide (CO2) and water (H2O) are released as byproducts. This loss of gas and water contributes to the decrease in mass. Additionally, any experimental losses during the transfer or handling of materials can further reduce the recovered mass of KCl.
The maximum number of grams of potassium that can be obtained from 100 grams of KHCO3 is?
The molar mass of KHCO3 is 100.12 g/mol. This means that 100 grams of KHCO3 contains 39.1 grams of potassium (K) ions.
Why is the mass of KCl recovered less than the starting mass HHCO3?
The mass of KCl recovered is less than the starting mass of HCO3 due to the loss of carbon dioxide (CO2) during the reaction. When HCO3 decomposes or reacts, it releases CO2 gas, which escapes into the atmosphere, resulting in a lower mass of the solid product, KCl. Additionally, any experimental losses during transfer or measurement could contribute to the difference in mass.
What is the maximum mass of iron that can be recovered from 12.4 of this ore?
s
What is the law stating that the mass off all substances involved in a chemical change will be the same after the change?
This is the law of mass conservation.
Is a person's mass less on the moon?
No- their weight is less, but mass is not changed.
Define law of definite proportion?
Law of Conservation of Mass is a relation stating that in a chemical reaction, the mass of the products equals the massof the reacants.
Would mass be more or less on the moon?
Mass is the same no matter where you are. Weight is less, but mass is the same.
What is also less if the mass is less in a volume?
Density. Mass is the product of volume and density, so therefore density is the ratio of mass to volume.
Which has less mass a marble or a baseball?
I'm pretty sure a marble has less mass
Will air at the top of the mountain contain more mass?
No , but less mass and less density .
