Ch3co3h + fe = ch3cooh + feo represents a( equation.
a.) balanced
b.) unbalanced

Balanced

Explanation:

2 Carbons per side

4 Hydrogens per side

3 Oxygen per side

1 Iron per side

Balanced

Explanation:

For an equation to be balanced, the number of atoms of each element on the lefthand side and right hand side of the reaction equation must be exactly the same.

There are four hydrogen atoms on each side

There is one carbon atom on each side

There are three oxygen atoms on each side

There is one iron atom on each side.

This is how to know a balanced chemical reaction equation.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
