Describe quantitatively, in words, the relationship between the mass attached to a vertical spring, and the time it takes for the spring to complete one full cycle.

Direct relationship.

Explanation:

There is a direct relationship between mass attached to vertical spring and the time period to complete one cycle because when the mass increases, more time is taken by the spring to complete one full cycle and vice versa. When the mass of the spring increases, the length of the spring is also increases so due to more length it takes more time to complete one full cycle as compared to less mass attached to the spring.

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
