Sugar dissolves in water. Which statement best describes what is happening? (1 point) Sugar stays together but in a liquid form that can no longer be seen in the water. Sugar stays together but in a liquid form that can no longer be seen in the water. Sugar slowly melts, turning from a solid to a liquid and combining with the water. Sugar slowly melts, turning from a solid to a liquid and combining with the water. The water molecules in sugar will separate from each other and combine with the water, releasing the sweetness into the water. The water molecules in sugar will separate from each other and combine with the water, releasing the sweetness into the water. A large collection of sugar molecules break into individual molecules and disperse in the water.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

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 :
