Which aspect is similar in both chemical and nuclear reactions? a. both involve nuclear fusion. b. both involve nuclear fission. c. both may release heat and light. d. both involve the exchange of electrons.

Hi!

The correct answer would be C

The key difference between the two types of reactions is that nuclear reaction involves a change in the nucleus of the atom(s) involved in the reaction, where as atoms in chemical reactions do not undergo any change in their nucleus.

Option A and B both deal with characteristics that pertain to only nuclear reactions, as both nuclear fusion and fission involve a change in the nuclear state of the initial elements.

Option D deals with the characteristic that pertains only to chemical reactions, which involve the transfer -gain or loss of electrons.

However, both of these types of reactions may be exothermic, with the capacity to release this energy as light, or heat.

Hence, Option C is correct

Hope this helps!

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
