Resistance depends on there properties of a wire:
- length (the longer the more resistance)
- area (the less area = more resistance and vise verse more area = less resistance)
- resistivity (the more resistivity the resistance)
Hope this helps :)
<span>q(rxn) = - [q(water)+q(bomb)]
q(rxn) = -{[ (1000g)(4.184)(5.0)] + [ (5.0)(0.10)]}
q(rxn) = - (20920 + 0.5)
Now we divide 3.5g
q(rxn)= - (20920)/(3.5g)
q(rxn) = 5977.14
And final answer, change is to Kilo joule unit
-q(rxn) = 5.23 KJ/unit</span>
Answer: an electron of an atom, located in the outermost shell (valence shell) of the atom, that can be transferred to or shared with another atom.
Answer:
DOUBLE DISPLACEMENT (mutual exachange of ions in aqueous form)
Ca is more reactive than Fe
hence it will displace Fe from ferrous nitrate solution and form Calcium Nitrate and Ferrous Sulphate will be formed
GOOD LUCK WITH THE FUTURE! :)
