I need more information to help you with this "work" because I don't have sufficient information to answer.
1-There are 18 volcanoes in the US with the potential to erupt again, all of them in Alaska, Hawaii and the West Coast states.
2-Rubies and sapphires are actually the same mineral - corundum. The basic chemical formula of corundum is Al2O3, but traces of iron stain the mineral red (ruby) while traces of chromium or titanium stain the mineral blue (sapphire).
3-Rubies, sapphires and emeralds are all more rare than diamonds.
4-Not all diamonds are transparent. They come in a variety of colors (called "fancies"), including yellow, green, blue, orange, brown ("champagne"), purple, grey, black (called carbanado, recently shown to be meteroic), milky white, pink, and red. Red is by far the rarest.
5-Antacids taste like chalk because they ARE chalk, a.k.a. calcium carbonate.
Hope this helps, Give a thanks ! Haha
The approximate size of solute particles in a solution is 1 nanometer.
Explanation:
Solute and solvent are the two components required to prepare a solution. Solute is the one which is dissolved in the solvent to prepare a solution. So solute should be of lesser concentration compared to the solvent. Also the particle size of solute should be lesser in size compared to the solvent for easy diffusion and substitution. Mostly it is seen that if the solute is finer and having a size of less than 1 nanometer can be easily dissolved in the solvent.
So for forming homogeneous solutions, the solute is considered to be of materials having the particle size of 1 nanometer for perfect dissolving.
Thus, the approximate size of solute particles in solution is 1 nanometer.
Answer:
2.7 x 10^-19 J
Explanation:
The formula needed for this problem is
E = hν
where E = energy, h = Planck's constant = 6.626x10^-34 and ν is the frequency
c = λν
where c = speed of light = 3x10^8, and λ = wavelength
3x10^8 = 7.35x10^-7 . ν
ν = 4.08 x 10^14 Hz
E = 6.626x10^-34 . 4.08x10^14 = 2.7 x 10^-19 J
