Which is an example of nuclear energy being converted into heat and light energy?
a) the sun
b) a volcano
c) a rocket engine
d) a coal burning power plant

A) the sun

Explanation: Nuclear energy can be defined as the energy which is present in the core of an atom. The core contains large amounts of energy present in the bonds that hold the nucleus together.

In sun nuclear fusion takes place where two or more atoms combine to form a larger atom, and a huge amount of energy is released in the process.

Rocket engines and a coal burning power plant convert chemical energy stored in the bonds of chemicals to heat and light energy. In volcanoes heat energy of the magma is converted to light energy and the mechanical energy is converted to sound energy.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
