2.
In your cell:
1) Clearly label which electrodes are the Anode and Cathode (1 mark)
2) Clearly show the direction of electron flow in the cell (1 mark)
3) Correctly write your reactions for each of the half-cells (1 mark)
4) Write the balanced net ionic reaction (1 mark)
5) Give two evidences of reaction you would "see" in this cell (1 mark)
Your answer

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

will have a gram-molecular weight of 352g.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

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
