An ideal gaseous reaction (which is a hypothetical gaseous reaction that conforms to the laws governing gas behavior) occurs at a constant pressure of 35.0 atmatm and releases 71.8 kJkJ of heat. Before the reaction, the volume of the system was 8.80 LL . After the reaction, the volume of the system was 2.80 LL . Calculate the total internal energy change, ΔEΔEDelta E, in kilojoules.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

particle   p is an electron and particle q is a neutron

your answer would be “dry”

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
