A fuel cell operates by converting chemical energy from fuel (typically hydrogen) and an oxidant (usually oxygen) into electricity, water, and heat. In this process, the total mass of the reactants (hydrogen and oxygen) is equal to the total mass of the products (water and any unused reactants), thus adhering to the law of conservation of mass. No mass is lost or created; it is merely transformed from one form to another. Hence, the mass before and after the reaction remains constant.
What else can I help you with?
Does 2Fe 3O 2Fe2O3 obey the law of conservation of mass?
Yes, the reaction 2Fe + 3O2 -> 2Fe2O3 obeys the law of conservation of mass because the total mass of the reactants (iron and oxygen) is equal to the total mass of the products (iron oxide).
Does this chemical recation PbCl2 Pb Cl2 obey the law of conservation of mass?
Yes, because the equation is balanced
What are conservation laws obey in each of the nuclear reaction?
Conservation laws in nuclear reactions include conservation of mass-energy, conservation of electric charge, conservation of momentum, and conservation of lepton number. These laws dictate that the total mass-energy of particles before and after a nuclear reaction must remain constant, as well as the total charge and momentum. Lepton number conservation ensures the number of leptons (like electrons and neutrinos) remains the same throughout the reaction.
What is the process called that is used to obey the law of conservation of mass?
The process used to obey the law of conservation of mass is known as balancing chemical equations. This involves ensuring that the number of atoms of each element is the same on both the reactant and product sides of the equation. By adjusting the coefficients in front of the reactants and products, one can reflect the same total mass before and after a chemical reaction. This principle demonstrates that matter cannot be created or destroyed in a closed system.
Does hydrogen peroxide obey the law of conservation of matter?
The law of conservation of matter is applied to processes not to a compound.
What types of changes observe the law of conservation of mass?
All changes, other than some nuclear reactions, must obey the Law of Conservation of Mass. Chemical reactions, physical changes, heating, cooling, and phase changes must obey the Law of Conservation of Mass.
Does 2Fe 3O 2Fe2O3 obey the law of conservation of mass?
Yes, the reaction 2Fe + 3O2 -> 2Fe2O3 obeys the law of conservation of mass because the total mass of the reactants (iron and oxygen) is equal to the total mass of the products (iron oxide).
Does this chemical recation PbCl2 Pb Cl2 obey the law of conservation of mass?
Yes, because the equation is balanced
Why must chemical equations be balanced using coefficients?
The number of atoms in the reactant and products must be equal to obey the law of conservation of mass.
What are some physical and chemical changes sugar can undergo?
It's either obey the law of conservation of mass, causing new matter to be created or it is an execption to the law of conservation of mass.
What are conservation laws obey in each of the nuclear reaction?
Conservation laws in nuclear reactions include conservation of mass-energy, conservation of electric charge, conservation of momentum, and conservation of lepton number. These laws dictate that the total mass-energy of particles before and after a nuclear reaction must remain constant, as well as the total charge and momentum. Lepton number conservation ensures the number of leptons (like electrons and neutrinos) remains the same throughout the reaction.
How would you have to change this chemical equation to make it obey the law of conservation of mass 2C C2H4?
To balance the chemical equation, you would need to change it to: 2C2H4 -> 4C + 4H2. This balances the number of atoms of each element on both sides of the equation, ensuring the law of conservation of mass is obeyed.
Does hydrogen peroxide obey the law of conservation of matter?
The law of conservation of matter is applied to processes not to a compound.
Why does rusting obey the law of conservation of mass?
Rusting, a chemical reaction between iron, oxygen, and moisture, obeys the law of conservation of mass because the total mass of the reactants equals the total mass of the products. During rusting, iron combines with oxygen to form iron oxide (rust), but no atoms are lost or created in the process. Thus, the mass remains constant, demonstrating that matter is neither created nor destroyed in chemical reactions. This principle is fundamental to all chemical processes.
Does Na H2O NAOHaq H2g obey the law of conservation of matter?
Yes, the equation obeys the law of conservation of matter. The number of atoms for each element is the same on both sides of the equation, indicating that no atoms are created or destroyed during the reaction.
How does the chemical equation for photosynthesis and cellular respiration obey the law of conservation?
the chemical equation for photosynthesis and cellular respiration obey the law of conservation is given below.the chemical equation for photosynthesis is :6CO2 + 6H2O ==> C6H12O6 + 6O2.The number of atoms are same on both sides even after the reaction.Hence, obey the law of conservationthe chemical equation for cellular respiration is :C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l) + Energy (as ATP) .The number of atoms are same on both sides even after the reaction.Hence, obey the law of conservation.
Do inclined planes obey the laws of energy conservation?
Sure, total energy is always conserved.
