Answer:
The particle which completes the given equation is :
Explanation:
The given reaction is of a fission reaction:

Total mass on the reactant side is equal to the total mass on the product side:
239 + 1 = 100 +A+ 2
A = 138
Sum of atomic numbers on the reactant side is equal to the sum of atomic number on the product side:
94 + 1(0) = 40 + Z + 2(0)
Z = 54
So atomic number 54 id of Xenon.
The particle which completes the given equation is :

Answer:
a
Explanation:
because they are easily reduced and oxidised
I think I remember hold on let me see if I can solve it
Answer:
<h2>f=a×m</h2>
m=1800kg
1800000g×10N/kg
18000000N force is required to life the car
Technological advances clearly.
Theories change due to other peoples view on the matter and how they experiment with it, but Technology advancements are the greatest factor of all. I mean seriously, we wouldn't know of cells before the microscope and when they first invented it, it advanced further and now we can see things on a whole deeper lever.
