The molecule cyanazine, once used as an herbicide, has now been phased out by the EPA because of its significant human toxicity. Add lone pairs, as needed, to the structure of cyanazine. Indicate the hybridization of the specified atoms. Be sure to consider any lone pairs you added to the structure. The structure of cyanazine has 5 atoms highlighted. Atom 1 is an N atom bonded to 2 C atoms and 1 H atom through single bonds. Atom 2 is an N atom bonded to one C atom through a single bond and one C atom through a double bond. Atom 3 is a C atom bonded to one C l atom and one N atom through a single bond and one N atom through a double bond. Atom 4 is a C atom that is bonded to three C atoms and one N atom through single bonds. Atom 5 is a C atom that is bonded to one C atom through a single bond and one N atom through a triple bond. What is the hybridization of atom 1

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

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 :
