Answer:
neither photosynthesis nor respiration.
Explanation:
Photosynthesis is the process by which the green plants, in the presence of sunlight makes their own food. In the process carbon dioxide is absorbed and oxygen is released.

Respiration is the intake of oxygen and the metabolism of the glucose in which it is breakdown and releases carbon dioxide.

In neither of the two processes, carbon dioxide is splitted.
A hydrate is a substance that contains water or its constituent elements. When this substance is heated, water is evaporated leaving an unhydrate. From this sample, the amount of water present would be equal to 2.73 g. Hope this answers the question. Have a nice day.

Answer:
Volume occupied by 10 grams of Lithium Oxide at STP is 7.52 L
Explanation:
STP (Standard Temperature and Pressure) : It is used while performing calculation on gases and provide standards of measurements while performing experiment.
According to IUPAC (International Union of Pure And applied Chemistry) , standard temperature is 273.15 K and Pressure is 100 kPa (0.9869 atm). At STP condition 1 mole of substance occupies 22.4 L volume .
Molar mass of Lithium Oxide = 29.8 g/mol
= 2(6.9) + 15.99 = 29.8
Mass of 1 mole
= 29.8 g
1 mole
occupies, Volume = 22.4 L
29.8 g
occupies, V = 22.4 L
1 g

1 g

10 g tex]Li_{2}O[/tex] occupies ,V =

V = 7.52 L
So, volume occupied by Lithium Oxide At STP is 7.52 L
