Answer:
Samarium
Explanation:
The element Sm describe is called Samarium. This element has unique sets of properties that makes it very unique and distinct.
The lanthanides are found in the f-block on the periodic table of elements.
This element is a moderately hard silvery metal that readily oxidizes in air. It assumes an oxidation state of +3. The element has an atomic number of 62
Subtracting the mass of (flask+water) from the empty flask gives:
95.023 g - 85.135 g = 9.888 grams of water
Dividing this by the given volume of 10.00 mL water gives:
9.888 grams of water / 10.00 mL of water = 0.9888 g/mL of water
Therefore, based on this sample, the density of water is 0.9888 g/mL, which is close to the usually accepted approximation of 1 g/mL.
I'm actually not sure... but maybe this will help!

Answer: Option B.
<u>Explanation:</u>
Water cycle is a cyclical process when the water evaporates from the ground and then falls back on the ground in the form of rain or snow. The various stages of this process are water evaporating from lakes, ground, rivers and so on.
Then it goes up in the air, condenses. And from the condensation process, the clouds are formed. When they cool down up in the air, then the water falls back on the ground and precipitates from the cloud in the form of rain or in the form of snow.
