The answer would be a. C2H4(ethylene)
1C2H4+3O2~>2CO2+2H2O
the one that is wrong is a. increase the molecular weight of the gas , the molecular weight never changes when a solid turns to a liquid or when a liquid turns to a gas .
Answer:
The object at 50°C will have a higher kinetic energy.
Explanation:
Temperature is a measure of the average kinetic energy of the particles in an object. As you introduce more energy into the system (e.g. heat the object), the particles on average move faster because they have more kinetic energy.
The compound that would have the highest osmotic pressure when dissolved in water is .
So, option D is correct one.
The dissociation of one molecule of gives the maximum number of ions when dissolved in water ( 4 ions ) . Osmotic pressure is a colligative property and depends upon number of solute particles present in the solution . The solution having maximum number of solute particles will have maximum number of the osmotic pressure .
All other given molecules gives less number of number of ions when dissolved in water as compare to of .
