A fusion reaction can be regarded as the type of reaction that occurs where two lighter elements come together in a type of reaction giving rise to a heavier/more massive element.
A fusion reaction always creates a more massive atomic nucleus (option c).
When the two lighter nuclei comes together in a reaction, a more heavier/massive nucleus is formed but its mass will still be less than the combined mass of the two reactant nuclei.
This also indicates that the left over mass may have been released as energy.

Answer:
Molar Mass of Calcium Carbonate = 100g
given mass = 50g
Number of mole of Calcium Carbonate =50/100 = 0.5 mole
Molarity = mole per litre of volume
Molarity = 0.5 /0.25 = 2mole/litre

Solid-When a solid is heated the particles gain energy and start to vibrate faster and faster. Initially the structure is gradually weakened which has the effect of expanding the solid. Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.
Liquid-As the liquid gets warmer more particles have sufficient energy to escape from the liquid. Eventually even particles in the middle of the liquid form bubbles of gas in the liquid. At this point the liquid is boiling and turning to gas. The particles in the gas are the same as they were in the liquid they just have more energy. At normal atmospheric pressure all materials have a specific temperature at which boiling occurs. This is called the "boiling point" or boiling temperature.
Description of Phase Change Term for Phase Change Heat Movement During Phase Change
Solid to liquid Melting Heat goes into the solid as it melts.
Liquid to solid Freezing Heat leaves the liquid as it freezes.
Liquid to gas Vaporization, which includes boiling and evaporation. Heat goes into the liquid as it vaporizes.
Gas to liquid Condensation Heat leaves the gas as it condenses.
Solid to gas Sublimation Heat goes into the solid as it sublimates.
C.) Copper ( Cu, atomic number) is an element which is malleable as well good conductors of heat and electricity. Hope this helps!
Answer:
B, A, C
Explanation:
the awnsers that are displayed are the only options that are new, and clean resorsces, we have always used oil in cars but hybrids are a new consept, same as wind power
Good LUCK!!
