After adding the CaCl2 the solution turned the water " hard". What effect did this have on the lathering ability od the soap? On the lathering abilitiy of detergent?
Strontium-90 is one of the products of the fission of uranium-235. This strontium isotope is radioactive, with a half-life of 28.1 yr. Calculate how long it will take for 0.600 g of the isotope to be reduced to 0.310 g by decay.
The mass spectrum of an organic compound shows the relative abundances of M to be 36.44% and M 1 to be 8.277%. Assuming the peaks are caused by 12C and 13C isotopes
