I think this is done to allow even distribution of temperature in all the regions of the calorimeter. That is to make sure that there are no hot or cold spots and also ensure that the measured temperature is the actual average temperature when the readings are taken by a thermometer.
Adhesion is responsible for a meniscus and this has to do in part with water's fairly high surface tension. Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus. They'll travel up the glass as far as water's cohesive forces will allow them, until gravity prevents them from going further. Cohesion is an intermolecular attraction between like molecules (other water molecules in this case).
What is in my calculator should be the answer u might have to round to the nearest tenths place
Answer:
The molarity is 0,35M
Explanation:
The molartity is moles of compound in 1 liter of solution :
20 L----------7moles compound
1 L..-----------x= (1L x7 moles compound )/20L= 0,35 moles compound--> 0,35M
