Jodied to run for exercise. To warm up, she walked at a constant speed for a distance of 100 min 100 s Then she increased her speed to 4 ms she ran at this speed for 5 min (300 s. At that point she began going up a steep it and her speed dropped back to 1 m/s. It took her 4 min (240 s) to reach the top of the him. At that time she stopped and rested for 3 min before continuing her run Construct a distance-time graph and a speed time graph of Jodi's motion Label the axes Then explain what is being shown as the slope of each Distance-Time Graph Speed-Time Graph

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.

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

it is stable as it is in group 0 which have full outer shells of electrons
