<span>A device that generates an intense beam of coherent monochromatic light (or other electromagnetic radiation) by stimulated emission of photons from excited atoms or molecules. Lasers are used in drilling and cutting, alignment and guidance, and in surgery; the optical properties are exploited in holography, reading bar codes, and in recording and playing compact discs.</span>
Answer:
prepared by mixing 20 ml of 0050 m hcl with 30 ml of 010 m ba oh 2 ... No. of milliequivalents of HCl = 2× 0.05 × 1. =1.
Explanation:
is this ?
This is in the assumption that these are the only 2 isotopes. This means that:
abundance of Li-6 = X
abundance of Li-7 = 1-X
Hence from your equations
6.9409 = (X * 6.015121amu) + ((1-X) * <span>7.016003amu</span>)
Solve for X = 0.075 or 7.50%
V is more reactive, hope this helps!
Hey ! I Don’t see the picture above.
