Answer:

The container contains 8 g of liquid water and no ice.  

Explanation:

An open system is a system that can exchange mass or energy with the environment.

If the total mass of the system after 6 h is different from 12 g, it must be an open system.

If the total mass of the system after 6 h equals 12 g, it must be a closed system.

The electronic transition in a hydrogen atom from n = 7 to n = 2 emits electromagnetic radiation having a longer wavelength than
Tema [17]

Answer: I'll leave the answer rounded to three sig figs.

mark me brainlist

So, you can say that in a hydrogen atom, an electron located on  

n

i

=

2

that absorbs a photon of energy  

4.85

⋅

10

−

19

 

J

can make the jump to  

n

f

=

6

.

Explanation:

The question wants you to determine the energy that the incoming photon must have in order to allow the electron that absorbs it to jump from  

n

i

=

2

to  

n

f

=

6

.

A good starting point here will be to calculate the energy of the photon emitted when the electron falls from  

n

i

=

6

to  

n

f

=

2

by using the Rydberg equation.
