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 =

V = 7.52 L
So, volume occupied by Lithium Oxide At STP is 7.52 L
Hydrochloric acid + Magnesium Hydroxide 》 Magnesium cloride + water.
The type of bond that will result in unequal sharing of electrons will be C. Nitrogen and Oxygen.
Answer:
is the electron relaxation time
is the mean free path
Explanation:
Given:
- electron density of aluminium at room temperature,

- resistivity of aluminium,

<u>From the Drude's model we have:</u>

where:
electron relaxation time
mass of a charge
magnitude of a charge
Putting respective values for electron:


<u>Mean free path is given as:</u>

where:
mean free path
average velocity of electrons
- Now we have the the general value of average velocity of electrons at room temperature:

So,
