Answer:
A body becomes weightless in a zero-gravity scenario and when a force is applied to a body that is equal and opposite to the force of gravity. If the body is falling only under the influence of gravity.
Explanation:
sodium element with 11 electrons,11protons and 12 neutrons
The Clausius-Clapeyron equation:
ln(P₁/P₂) = ΔH/R * (1/T₂ - 1/T₁)
-25 °C = 248 K and pressure is 344 torr
-6.4 °C = 266.6 K and pressure is 760 torr (atmospheric)
Using the equation:
ln(760/344) = ΔH/62.364 * (1/248 - 1/266.6)
ΔH = 175.7 kJ/mol
→ 
is a decomposition reaction. Barium chlorate decomposes to give barium chloride and oxygen.
<h3>What is decomposition reaction?</h3>
A decomposition reaction can be defined as a chemical reaction in which one reactant breaks down into two or more products.
A decomposition reaction produces multiple products from a single reactant.
Combustion reactions are the combination of some compound with oxygen to make oxides of the other elements as products.
Hence, → is a decomposition reaction. Barium chlorate decomposes to give barium chloride and oxygen.
