WILL MARK BRAINLIEST PLZ HELPP
Change the following in to chemical equations and balance them.
a) Hydrogen gas combines with nitrogen to form ammonia.
b) Potassium reacts with water to give potassium hydroxide and hydrogen gas.
c) Aluminium metal reacts with ferric oxide giving aluminium oxide and iron.
d) Ferric oxide reacts with aluminum metal to form aluminum oxide and iron.
e) Barium hydroxide reacts with hydrogen bromide to give barium bromide and water.
f) Calcium carbonate on heating gives calcium oxide and carbon dioxide.

The answer to your question is below

Explanation:

I just write the formulas of the reactants and products and balanced the reactions.

a)

          3H₂(g)  +  N₂(g)   ⇒   2NH₃

b)

          2K  +  2H₂O  ⇒   2KOH  +  H₂ (g)

c)

         2Al(s)   +  Fe₂O₃  ⇒   Al₂O₃  +  2Fe

d)

         Fe₂O₃  +  2Al   ⇒  Al₂O₃  +  2Fe

e)

         Ba(OH)₂  +  2HBr   ⇒   BaBr₂  +  2H₂O

f)

         CaCO₃  + Δ ⇒  CaO  + CO₂

it would be a gas formation

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
