Calculate the change in enthalpy for reaction 2.
reaction 1: c3h8(g)+5o2(g)→3co2(g)+4h2o(g), δh1=−2043 kj
reaction 2: 3c3h8(g)+15o2(g)→9co2(g)+12h2o(g), δh2=?

What must be in balance for temperatures to remain constant?

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
