Select the word from the list that best fits the definition process by which sediment is removed from its source deposition erosion rock texture rock cycle composition the correct answer is composition

Option (2)

Explanation:

The process by which the rock materials (sediments) are transferred or removed from the source area to other places is known as erosion.

This erosion is caused by the agents such as wind, water, and ice.

The lighter materials are generally transported, but when the flow rate is very high, then it can carry coarser particles also. The process of erosion occurs only on the surface of the earth, and it gives the shape of the features that are present on it.

Hence, the correct answer is option (2).

  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
