Which statement is correct about an element’s identifying spectrum? a) The light reflected off an element produces a unique iden
Ronch [10]

Answer:

correct answer is option d (Light emitted by an element produces a unique identifying spectrum.)

Explanation:

Each element has different atomic number and atoms of an element can radiate a certain amount of energy. Different elements have different atomic spectrum and it can be used to determine the composition of a material.

When atoms are excited to higher energy state after some time they came back to lower state by emitting their excess energy in the form of light. This light has certain wavelength. This emitted light can be seen as a series of different colored lines and between two colored lines there is a dark space. This series of colored lines is called a line spectra or atomic spectra.

Which data set has the largest range?
MrRissso [65]

Answer:

Option C

Explanation:

We have to check range of all options first

For A:

Largest Value: 5

Smallest Value: 1

So range = Largest value - smallest value

5-1 = 4

For B:

Largest Value: 6

Smallest Value: 4

Range = 6-4 = 2

For C:

Largest Value: 9

Smallest Value: 1

Range = 9-1 = 8

For D:

Largest Value = 9

Smallest Value = 3

Range = 9-3=6

So, the data set in option C has the largest range

Explain what nuclear fusion is in the role it plays in Stars. DO NOT LOOK UP ANSWERS​
Aloiza [94]

Answer:

Stars are powered by nuclear fusion in their cores, mostly converting hydrogen into helium. The production of new elements via nuclear reactions is called nucleosynthesis. A star's mass determines what other type of nucleosynthesis occurs in its core (or during explosive changes in its life cycle).
