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.
How do you solve Hess's law problems?
To solve Hess's law problems, first write out the chemical equations for all reactions involved. Then calculate the enthalpy change for each reaction. Finally, add or subtract the enthalpy changes to obtain the overall enthalpy change for the desired reaction.
What is the equation for a neutralisation reaction?
use the formula for enthalpy change for the reaction of an acid and base to produce 1mol of water. dH=mc(dT)/n where H = enthalpy m = mass of system c = specific heat capacity of system T = temperature of system n = number of moles reacted
Equation for the heat of formation of carbon disulphide?
C + 2S -> CS2 Enthalpy of formation is the change in enthalpy for the formation of a substance from its elements.
What is the difference between a thermochemical equation and a traditional chemical equation?
Thermochemical equation includes enthalpy ( ΔH ) change in it.
How is the enthalpy of reaction related to the enthalpies of formation for the products and reactants?
The difference between the enthalpy of formation of the products minus the enthalpy of formation of the reactants is the enthalpy of the reaction
Ethanol CH3CHO - how to write an equation to represent the enthalpy of formation?
CH3CHO+HCl
How do you calculate the boiling point of water-ethylene glycol mixture?
depends on the percent solution. here is an equation for a 50% wt solution i believe enthalpy = -5E-06tx^3 + 0.0033tx^2 + 3.1782tx + 0.0492
What is the difference between enthalpy change and enthalpy change per mole?
Enthalpy is the energy absorbed or lost from a reaction, but enthalpy change per mole is the amount of energy lost per mole, so in order to get the overall enthalpy from the change per mole, you must multiply that value by the amount of moles used in the reaction.
Hcl nahco3 nacl H2O CO2 enthalpy of reaction?
NaCl+H2O COMPELATE THE EQUATION
How do you calculate the mass of an object in a chemical equation?
balance your chemical reaction equation then calculate moles, then calculate weight.
How do you calculate NGDP?
To calculate NGDP, the numbers that are needed must be entered to the equation. The proper step for the equation must be followed to calculate the NGDP.
