Answer: The complete reaction is as follows.
Explanation:
When nucleus of two or more atoms are bombarded together then it leads to the formation of new particles with new identity. This type of reaction are called nuclear reaction.
For example, 
Here, nitrogen atom when bombarded with a neutron then it is forming hydrogen and a carbon atom.
As total atomic mass on reactant side is (14 + 1) = 15
So, the atomic mass of carbon formed on product side is (15 - 1) = 14.
The number of protons holded by this carbon atom is (7 - 1) = 6.
Therefore, we can conclude that the complete reaction is as follows.
Answer:
c.
Explanation:
If the object starts to slide it must be on a slope.
There are 2 forces acting on the object - gravity and the friction between the object and the surface.
If sliding starts then the forces must be unbalanced.
The force of gravity is greater than the friction.
A. 1 proton and 1 neutron

Answer:
B
Explanation:
The normal way to express an energy reaction is to put the energy on the left. Then you can make a rule.
- If the energy on the left is plus then the reactants require energy. The reaction is endothermic -- energy is taken from the environment.
- If the energy is minus when it is on the left. then the reactants give up energy. The reaction is exothermic and energy is given to the environment.
2CO(g)+O2(g) - energy --> 2CO2(g)
Exothermic
