i really need help

joftheworld · Answer

is this science ?

anonymous · Answer

ye but nobody is active its dead

agreene · Answer

It will be exothermic because the energy is being taken in on the left side of the reaction,
which means that the system is taking in energy to do the reation

agreene · Answer

erg
i meant endothermic

joftheworld · Answer

its exothermic only

joftheworld · Answer

he reaction releases energy - it is an exothermic reaction

anonymous · Answer

it cant be bc i got it wrong

anonymous · Answer

I think -gonic is the suffix you're looking for.

anonymous · Answer

Whoops, didn't see the mult choice...

anonymous · Answer

Energy goes IN.

In = Endo-

agreene · Answer

endo-  taking in 
thermic-  temp/energy

anonymous · Answer

kk ill try

agreene · Answer

$$A +\Delta h\rightarrow B$$is endothermic$$A\rightarrow B+\Delta h$$
is exothermic

joftheworld · Answer

yeah sorry its endo.. my bad

anonymous · Answer

@agreene I think -gonic and -thermic are interchangeable. -gonic seems to have more a biochemical connotation, while -thermic a more physical/chemical one.

agreene · Answer

Yeh, endogonic tends to refer to anabolic metabolism and exogonic is catabolic, I think
