A scientist measures the standard enthalpy change for this reaction to be -146.7 kJ/mol. NH NO3(aq)-N20(g) + 2 H2O(1) Based on this value and the standard formation enthalpies for the other substances, the standard formation enthalpy of N2O(g) is kJ/mol.​

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

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.

if you're asking what comes out, it's steam.
