Afusion reaction takes place between carbon and another element. neutrons are released, and a different element is formed. the different element is
a) lighter than helium. b)heavier than helium. c)the same weight as helium. d)dependent on the element that reacted with carbon.

Answer is: B) heavier than helium.

Helium (He) is an element with mass number 4 and carbon (C) is an element with mass number 12. Carbon has three time bigger mass numer, so new element is heavier thah helium.

For example, nuclear reaction: ²⁴⁹Cf + ¹²C → ²⁵⁷Rf + 4n°.

Californium-249 has mass number 259, carbon-12 has mass number 12 and rutherfordium-257 has mass number 257.

Mass number (A) is the total number of protons and neutrons in a nucleus.  

Sum of mass numbers of californium-249 and carbon-12 is 261 (249 + 12), but four neutrons are produced, so new element has mass number 257 (261 - 4).

Explanation:

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

the movement of aircraft through clouds can even cause lightning strikes. a single lightning event is a "flash", which is a complex, multi-stage explosively ejected.
