The right answer is ( D ) Movement Of Tectonic Plates
Answer:
a)<em> Balanced equation:</em>
An equation is called balanced if there are same number and same type of atom on both sides of the equation.
b)<em>Reason:</em>
2KClO3--------2KCl + 3O2
Consider this equation in the reactants there are 2KClO3 and in the product there are 2KCl+3O2 . So reactants =products which is a case of balanced chemical equation .
Explanation:
Explanation:
Adding a neutron will not affect the charge. The atom remains neutrally charged.
Since the charge of a neutron is neutral, or 0, the charge is not affected. Protons have a positive charge, whereas electrons have a negative charge. Since there are an equal number of protons and electrons, they cancel out.
Adding a neutron also increases the mass by 1. The mass of a neutron is 1 amu. The atomic mass is calculated by protons + neutrons.
Originally, the mass is 7 (because 3+4). The mass would now be 8 (because 3+5).
