Answer:
Atomic emission spectrum came out by a series of colored lines
Explanation:
When electricity is passing through an element or when it is viewing through a prism, a unique spectra of light emitted by an element is called atomic emission spectra. They are acting as an element of finger print because they are unique. When we are seeing a set of colored lines or a black background , it is an emission spectrum. If we are watching black lines on a colored background it is absorption spectrum. In electromagnetic spectrum the visible portion are the colors.
In nucleus electrons can exist in some areas are known as shells. Shell corresponds an energy level that is designed by a quantum number n. The lowest energy level electrons are close to the nucleus.
An atom is shone by light, its electrons absorbs photons and it gain energy, and jump to higher level.
Solar Cycle 25 is now underway and expected to peak with 115 sunspots in July 2025.
Answer:
when it comes to adding or subtracting numbers, his final answer should have the same number of decimal places as the least precise value.
For example if you add 2 numbers; 10.443 + 3.5 , 10.443 has 3 decimal places and 3.5 has only one decimal place.
Therefore 3.5 is the less precise value.
So when adding these 2 values the final answer should have only one decimal place.
after adding we get 13.943 but it can have upto one decimal place. then the second decimal place is less than 5 so the answer should be rounded off to 13.9.
the answer is the same number of decimal places as the least precise value
Explanation:
I think this is the answer I'm not sure
Answer:
CHARLES' LAW
given:
= 600 mL = 0.6 L
= 27 °C = 300.15 L
= 77 °C = 350.15 L
conversion:
= 600 mL (1 L / 1000 mL)
= 0.6 L
= 27 °C + 273.15 K
= 300.15 K
= 77 °C + 273.15 K
= 350.15 K
solution:
= ( × ) ÷
= (0.6 L × 350.15 K) ÷ 300.15 K
= 0.7 L
