Answer:
Well, to separate salt from water, you would stir the two together to create a homogenous mixture. Then you would boil the mixture; all the water would evaporate, leaving behind the salt
Explanation:
This equation relates all three variables, so just plug in all of the given values. Don’t forget to convert deltaS into kJ/K because Gibbs free energy is measured in kJ. The K used in temperature cancels out the K in kJ/K, leaving only kJ as your units. Don’t forget sig figs!
Answer:
Cd(s) + CuSO4(aq) = Cu(s) + CuSO4(aq)
Explanation:
cadmium metal is a solid, so it will be labeled as Cd(s)
"reacts with a" means it is adding something: so the symbol will be "+"
copper (ll) sulfate is CuSO4, and "solution of" means it is aqueous "aq"
"to produce" means it is creating something, so instead of the "=" it would be an arrow
pure copper is labeled as Cu, and it is a solid
it repeats "solution of cadmium (II) sulfate" so it becomes CuSO4(aq)
Answer:
as individual atoms
Explanation:
toms bond together to form compounds because in doing so they attain lower energies than they possess as individual atoms. A quantity of energy, equal to the difference between the energies of the bonded atoms and the energies of the separated atoms, is released, usually as heat.
Answer:
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
