Answer: It is important for an equation to be balanced because if it is not then the reactants won't match the products.
Explanation: I don't know if you will understand this but here:
Let's say you're cooking eggs, you're reactants so to speak would be 3 eggs and 1 tablespoon of oil so you put it together using heat and a pan. Your products have to match what you have in the beginning. You cannot have an equation that looks like this
Reactants = 3eggs + 1Tbsp oil ---pan/heat---> 6eggs + 1 cup of oil
You cannot get something from what you don't have. The number of how much of an element you have must be the same of both sides of the equation.
Answer:
9
Explanation:
mass number = protons + neutrons
= 4 + 5 = 9
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:
Thomson saw the atom to be a spherical cloud of positive proton matter with electrons dispersed throughout it. Then the gold foil experiment is when Rutherford shot alpha particles at a sheet of gold foil and when there was deflection he concluded there was a dense part in the center of an atom with he called the nucleus made up of neutrons and protons.
