Answer:
The answer to your question is V2 = 1244 L
Explanation:
Data
Temperature 1 = 11°C
Volume = 1.03 x 10³ L
Temperature 2 = 70°C
Volume 2 = ?
To solve this problem use the Charles' law
V1/ T1 = V2 / T2
-Solve for V2
V2 = V1T2 / T1
Process
1.- Convert temperature to °K
Temperature 1 = 11°C + 273 = 284°K
Temperature 2 = 70°C + 273 = 343°K
2.- Substitution
V2 = (1.03 x 10³)(343) / 284
3.- Simplification
V2 = 353290 / 284
4.- Result
V2 = 1244 L
3) Answer is: because elements have different emmision spectrum.
Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state. Each element's emission spectrum is unique.
4) Answer is: lithium chloride and sodium chloride do not have similar colors.
Lithium ion has red and sodium ion has yellow emission spectrum.
5) Answer is: because metals have valence electrons in different energy shells.
Each transition has a specific energy difference.
6) Answer is: salts of alkaline and earth alkaline metals.
For example barium chloride gives green light.
Helium is a nonmetal. There are several reasons for this, it is unable to donate electrons and It has an extremely low melting point.
In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.
Oxygen. Is the correct answer
Oxygen has the same number of valence electrons as sulfur. An ion can be an element that gained or lost an electron.
