Answer:

1. 2Al + Cl2 = Al2Cl2

2 TiCl4 + 2Na = Ti + 2NaCl2

3. H2O2 = H2O + O2

4. Na2S + 2HCl = H2S + 2NaCl

5. Mg(OH)2 + 2HCl = MgCl2 + 2H2O

1. 3O2 = 2O3

When the temperature of the air is 25°C, the velocity of a sound wave traveling through the air is approximately
Vitek1552 [10]

Answer ; The correct answer is : 346 m/s .

Sound is a type of longitudinal wave , which is produced when a matter compress or refracts .

Speed of sounds depends on factors like medium , density , temperature etc .

Effect of Temperature on speed of sounds :

When the temperature increases , molecules gains energy and they starts vibrating and with higher temperature vibration becomes fast . So the waves of sounds can travel faster due to faster vibrations . Hence , speed of sounds is directly proportional to the temperature or speed of sounds increases with increase in temperature .

The speed of sounds at 0⁰C is 331 \frac{m}{s}

The relation between speed of sound and temperature is given as :

V = 331 \frac{m}{s}  + ( 0.6 \frac{m}{s- ^0C} * T  )

Given : Temperature = 25 ⁰ C

Plugging values in formula =>

V = 331 \frac{m}{s} + (0.6 \frac{m}{s-^0C}  * 25^0C)

V = 331 \frac{m}{s} + 15 \frac{m}{s}

V =  346 \frac{m}{s}
