1. La materia puede estar principalmente en tres estados: sólido, líquido y gaseoso. El modelo que mejor representa la unión (Cohesión) entre las moléculas de un sólido es: A. Porque tienen forma y volumen fijo B. Porque tienen forma variable y volumen fijo C. Porque tiene forma y volumen variable D. Porque

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 :

idk what is it? is this a question that you know the answer or u dont

c. electrical charges of ionic bonds.
