The stannous fluoride in a 10.00 g sample of toothpaste was extracted and then precipitated with lanthanum nitrate solution. 0.105 g of precipitate was collected. What is the mass of SnF2 present in the toothpaste sample? What is the mass percentage of stannous fluoride in the 10.00 g sample of toothpaste? The percentage of SnF2 listed on the box was 1.50%. What does this say about our percent yield of the extraction/recovery process? ​

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

increased stability in the completion of fluorine's outer shell.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
