Q
can you think of a reason
A
because the solar power is located in a dessert
3
Q
lithium-ion batteries
A
because they lose charge over time
4
Q
how do you think we can determine how much energy
A
burn it and measure how much heat

9
Q
the combustion of octane
A
it releases heat….higher energy
10
Q
we saw in the calorimeter
A
…. endothermic

Q
which of these reactions
A
ice melting
13
Q
since the unit of ∆H is J
A
the uniy for ∆G is J
14
Q
the reaction of the holotable
A
we subtract a positive value
