When a chemical equation contains the same number of atoms on both sides, the equation is balanced.
t/f

True.

The equation is balanced.

Explanation:

A balanced equation of any particular reaction is often identified when the significant  total number of atoms in each of the  significant elements present in the reactant side  often quoted as the left side is identically same as the number of atoms present in the adjacent side which is the product side also known as right side of the present reaction.  Hence it generally implies for a balanced equation to be, the number of moles on one  side of the reactant side  as well as the product side should also be similar i.e equal.

Example

Here,

No of atoms present in reactant side = 2

No of atoms present in product side= 2

Therefore, Atoms present in the reactant side= atoms present in the  product side

Hence, the equation mentioned above is chemically balanced  on both sides.

a and b sometimes have a positive value

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
