Look at this image.

O is written on top with four dots around it. There are two H written below O. Straight lines are drawn between O and each H.

What do the dots in this image represent?

Ionic bonds in water
Covalent bonds in water
Shared valence electrons
Non-bonded valence electrons

c, shared valence electrons

Explanation:

the hydrogen atoms share electrons with the oxygen atom and create a covalent bond.

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 :

just did the assignment and the answer was #1 +2 n
