Answer:
The value of n in the hydrate formula is 5 ,
.
Explanation:
Mass of hydrate of copper sulfate = 14.220 g
Moles of hydrate of copper sulfate =
Mass of copper sulfate after heating = 8.9935 g
Moles of copper sulfate = 
Solving for n, we get:
n = 5
The value of n in the hydrate formula is 5 ,.
Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.
hope this helps you! :-)
The correct chemical formulae is CsBr
Answer:
0.67 mole/litre
Explanation:
the molarity equall no. of moles ÷ volume of sol.
I choose the option A.
The electron absorbs energy from specific wavelength then moving from a lower energy orbital to a higher energy orbital.
