Answer:
in nuclear fusion deep in the interiors of stars
Explanation:
Nuclear fusion -
It is the type of reaction , where two or more atomic nuclei of the atom merges together to release two or more different nuclei along with some subatomic particles , is referred to as a nuclear fusion reaction .
The reaction can very well be done on stars , because of very high energy .
Hence , a nuclear fusion occurs deep inside the stars .
Answer:
The answer would be cation
Explanation:
It has 7.22 moles.... mole =mass/molar mass
molar mass of H2O=18
130/18=mole
Answer:
54.075KJ
Explanation:
Since methane is the limiting reactant.
From the reaction equation,
16 g of methane absorbs 206 KJ of energy
4.20 g of methane will absorb 4.20 × 206/16 = 54.075KJ of energy was absorbed.
From the equation, the value of the enthalpy of reaction is positive, this means that energy is absorbed in the reaction of methane and water. Hence the answer.
warm air rises because of convection.
A student holds the back of his hand near an iron to see if it's hot. The heat transfer is conduction.
Warm water moves throughout a mattress because of ... why is there warm water in a mattress again? Convection, I guess.
In a swimming pool, the water near the surface is warmer because of convection and solar radiation; it's closer to the Sun than the bottom of the pool, so it receives more thermal radiation, making it warmer.
