Two students are planning an investigation to determine if ionic or covalent bonds have stronger intermolecular forces. They are using salt (ionic), sugar (polar covalent), and moth balls (nonpolar covalent). Which property below would be the LEAST helpful in determining what bond type has the strongest intermolecular forces? Flammability

Solubility in water

Conductivity in water

Melting Point

conductivity in solid state/ in water

Explanation:

conducitvity in water state would be least helpful when trying to determine the bond type that has the strongest intermolecule force, becuase they (salt and water) both would dissolve in water the same.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

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 :
