Arrangement of electromagnetic radiation in increasing order of energy or decreasing order of wavelength is called as electromagnetic spectrum. Electromagnetic radiation is arranged in following order in electromagnetic spectrum:
Radiowaves, Microwaves, Infrared waves, Visible waves, UV rays, X rays
Following are contrasting feature of microwaves and visible ways
1) Wavelength: Microwave (0.1 to 100 cm); Visible rays (400 - 800 nm)
2) Frequency: Microwave (300 GHz – 300 MHz); Visible rays (770 THz – 400 THz)
3) Energy: Microwave (<span>1.24 meV – 1.24 </span>µeV); Visible rays (<span>3.2 eV – 1.7 eV</span>)
Computers can't really detect such a low intensity.......?, I hope I'm right.
Answer:
0.0831 moles of NaOH were in the original mixture
Explanation:
The strontium hydroxide, Sr(OH)2, requires 2 moles of HCl per mole of hydroxide to be neutralized.
The sodium hydroxide, NaOH, requires 1 mol of HCl per mol of hydroxide.
To solve this question we must write 2 equations:
<em>(1) </em>0.19mol = X + Y
<em>Where X = Moles NaOH; Y = Moles Sr(OH)2</em>
The moles of HCl required are:
0.100L * (2.969mol / L) = 0.2969 moles HCl
0.2969 mol = X + 2Y<em>(2)</em>
Replacing (1) in (2):
0.19mol - Y = X
0.2969 mol = (0.19mol - Y) + 2Y
0.1069mol = Y
Moles X = Moles NaOH:
0.19mol = X + 0.1069mol
X = 0.0831 moles of NaOH were in the original mixture
The density of marble is between 2.6 and 2.8 grams per cm³ .
Density doesn't depend on how much mass or volume of it you have.
The density of a chip of it is the same as the density of a truckload of it.
