Answer:

Explanation:

17. it goes from solid copper to aqueous copper:

Cu(s) --> Cu₂(aq) + 2e⁻

18. complete ionic:

Cu(s) --> Cu₂(aq) + 2e⁻

19. net ionic, must include only reacting species, so

Cu(s) --> Cu₂(aq) + 2e⁻

20. this type of reaction is dissolution reaction(redox reaction)

copper reduced from Cu²⁺ to Cu.

9966 [12]

To solve this problem, we must be given first the density of air at 20 degrees Celsius. Looking up online, this is equal to:

density air (20C) = 0.0012041 g/mL

so that the volume is:

volume balloon = 0.57 g / (0.0012041 g/mL)

What is the work function of gold metal in kJ/mol if light with λ = 234 nm is necessary to eject electrons?
Tju [1.3M]

Answer

512kj/mole

Explanation:

What is the work function of gold metal in kJ/mol if light with λ = 234 nm is necessary to eject electrons?

The energy can be calculated using below expresion;

E = hc/λ

Where h= planks constant= 6.626 x 10^-34

c= speed of light= 3 x 10^

λ= wavelength

hc= (6.626 x 10^-34 x 3 x 10^ 8)
