1. How is the KM system at NASA different from other KM systems that you have studied within the chapter? How is it similar? 2. What steps can NASA take to make sure that the KM system is better utilized by individuals and teams? 3. What can NASA do to ensure that individuals and teams can find what they need within the mountain of data residing within the KM system? 4. Is NASA’s KM system, as it exists now, a good way to combat the type of failures the agency has experienced in the past? If not, how could the KM system be changed to support mission success? 5. Are there other measures that NASA should take in addition to or in conjunction with the development of its KM system?

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
