What quantities do not change during a nuclear reaction?
If you consider the equation, E=mc2, you can see that an amount of mass can be considered as equal to an amount of energy. In other words, we could take all the mass in a nuclear reaction and figure out how much energy that represents. If you add that to the amount of energy present at the same time, you get a summation of energy (some of which is mass represented as energy). That amount of energy does not change in a nuclear reaction.
Equation for calculating if mass is known?
according to energy heat equation e=mc^2 where c is speed we can calculate energy
How would cooling down a solution change reaction time?
In general, cooling a solution slows the reaction. You can use the Arrhenius equation to figure out what effect a given temperature will have on a particular reaction (you'll need to know the activation energy).
What is the sign for Energy change of an endothermic reaction?
The products of the reaction will have less energy than the reactants
Why is mass energy not apparent for chemical reactions?
According to Einstein's equation, E = mc2, any time there is energy released by a chemical reaction there must be a change in mass. The factor, c2,is such a hugh factor that the mass change is so small that it is not measurable by our balances.
How bond formation and bond breaking related to enthalpy?
Enthalpy is the measurement of total energy change of a reaction. The energy of bond formation and bond breaking can be used to calculate the bond enthalpy of the reaction. Bond enthalpy is the enthalphy change when 1 mol of bond is broken. Therefore the general equation to calculate the enthalpy change is energy of bond broken subtract by energy of bond formation.
What equation is used to calculate the free energy change of a reaction?
Delta G (written triangle G) = Delta H -T Delta S
What is S in the equation delta G equals delta H minus TdeltaS?
The change in enthalpy between products and reactants in a reaction

Do you have an equation to calculate kinetic energy?
KE=1/2mvsquared
Who proposed the equation to calculate the energy of a photon?
Albert Einstein
What is the equation that defines energy?
There are different types of equations to calculate different types of energy.
Equation for calculating if mass is known?
according to energy heat equation e=mc^2 where c is speed we can calculate energy
The change in energy represented by a thermochemical equation is always?
The change in energy represented by a thermochemical equation is directly proportional to the number of moles in substances undergoing a change.
How would cooling down a solution change reaction time?
In general, cooling a solution slows the reaction. You can use the Arrhenius equation to figure out what effect a given temperature will have on a particular reaction (you'll need to know the activation energy).
What type of reaction is exothermic reaction?
The reaction in which energy is being released, and the overall energy change (enthalpy) is negative.
What is equation to calculate potential energy?
work=force x output
