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 occupies ,V =
1 g occupies ,V = 0.7516 L
10 g tex]Li_{2}O[/tex] occupies ,V = L
V = 7.52 L
So, volume occupied by Lithium Oxide At STP is 7.52 L
Explanation:
The reaction between calcium hydroxide and nitric acid is as follows.
Number of reactant atoms are as follows.
- Ca = 1
- O = 4
- H = 3
- N = 1
Number of product atoms are as follows.
- Ca = 1
- O = 4
- H = 2
- N = 3
To balance the given chemical equation, multiply by 2 on reactant side and multiply
by 2 on the product side.
Therefore, the balanced chemical equation will be as follows.
