Sodium chlorate decomposes into sodium chloride and oxygen.
The reaction is
NaClO3 --Δ--> NaCl + O2
The Δ means that heat is used
This equation is still not balanced.
Balancing the equation
2NaClO3 --Δ--> 2NaCl + 3O2
The equation is now balanced.
Hurricanes derive their energy from the Latent heat of condensation.
Hence, Option (1) is correct answer.
<h3>What is Latent Heat ? </h3>
The heat that is released or absorbed during a phase change of a substance is known as Latent heat.
<h3>What is Hurricanes ?</h3>
Hurricanes is basically a type of storm called a tropical cyclone. These are intense low pressure areas. Hurricanes derive their energy from the latent heat of CONDENSATION.
Thus from the above conclusion we can say that Hurricanes derive their energy from the Latent heat of condensation.
Hence, Option (1) is correct answer.

Answer:
17.92 litres.
Explanation:
1 mole of a gas occupies 22.4 litres at STP.
So 0.8 moles occupies 0.8 * 22.4
= 17.92 litres.
Acceleration is the rate at which velocity changes; here we are told the speed increases by 9.8m/s for each second of travel
assuming the object starts at rest, the object has a speed of 9.8m/s after one second, and a speed of 19.6m/s after two
mathematically, we write
v= at
where v is the velocity, a is the acceleration and t is the time of travel
so v= at = 9.8m/s/s x 2s = 19.6m/s
