Answer the lab question (“What is the effect of temperature on the solubility of a solid in a liquid?”) with a hypothesis:

The solubility of a solid in a liquid increases with increase in temperature.

Explanation:

Solubility is defined as the amount of solute that can be dissolved in a given amount of solvent. For example in 100g of water at 25 degree Celsius 36 g of sodium chloride can be dissolved.

When a liquid is heated its kinetic energy increases and the particles start to vibrate or move. So when more amount of solute (sodium chloride) is added the solute particles finds its way into the solvent molecules (water) and hence the solubility increases.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

plasma - state of matter made up of electrically charged particles
