Why does the mass stay the same when hydrogen burns in oxygen and water is made?

Law of conservation of mass: total mass of Reactants AND Products stays UNCHANGED during ANY reaction (except nuclear reactions like fusions)


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.


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.


What does MASS BEFORE MUST EQUAL MASS AFTER mean?

"MASS BEFORE MUST EQUAL MASS AFTER" refers to the principle of conservation of mass, which states that in a closed system, the total mass remains constant over time, regardless of the processes occurring within the system. This means that during any chemical reaction or physical change, the mass of the reactants must equal the mass of the products. This fundamental concept is crucial in chemistry and physics, as it helps in understanding how substances interact and transform without any loss or gain of mass.


Is the total mass of all chemical reactions less than the total mass of the reactants?

No, the total mass of all chemical reactions remains constant and is equal to the total mass of the reactants. This is known as the principle of conservation of mass in chemistry. Any perceived changes in mass during a chemical reaction are due to the rearrangement of atoms, not a loss or gain of mass.

Do priests say mass everyday?

The pope says Mass daily in his private chapel in the Vatican which is usually attended by just a few close associates. He says Mass in St. Peter's Basilica only on special occasions such as Easter, Christmas and other major feasts. Like any other priest, the Holy Father only celebrates one Mass a day, with three each on All Souls Day and Christmas.Clarification:If priests are lacking, the local ordinary may permit priests, for a just cause, to celebrate twice a day and even, if pastoral need requires it, three times on Sundays and holy days of obligations. (Canon 905) The church in the United States was granted an indult so that priests can celebrate three Masses on any day if needed.

What clothes did a bishop wear during the first century?

A:Scholars say that the role of bishop did not exist in the first century, so it is not possible to say that bishops wore anything. As the numbers of Christians grew during the second century, it became necessary to appoint bishops to oversee priests and deacons, providing them with instructions about their roles, as shown in the Pastoral epistles. .Catholic AnswerWe don't really have any pictures or descriptions of the early Bishops of the Church, we can assume that, when not celebrating Mass, they wore street clothes like the early priests and deacons, and wore roughly the same thing at Mass as, to this day, Mass vestments are based on the early Roman street clothes.

Why can't matter be creAted from energy?

In any reaction, or process, both the amount of mass and the amount of energy remain constant. You might say that mass has energy, and energy has mass. Any mass or energy "created" during a reaction was already present previously.

Why is mass conserved during the combution of methane?

Mass is conserved during the combustion of methane due to the principle of conservation of mass, which states that matter cannot be created or destroyed, only transformed. In the case of methane combustion, the reactants (methane and oxygen) are converted into products (carbon dioxide and water) through a chemical reaction. The total mass of the reactants is equal to the total mass of the products, demonstrating the conservation of mass.
