What can we say about this chemical equation? (check all that apply) 2h2 + o2 --> 2 h2o group of answer choices mass is not conserved. this chemical equation is balanced this chemical equation is not balanced. mass is conserved

This chemical equation is balanced

Mass is conserved

Explanation:

Properly writing the equation:

               2H₂ + O₂ → 2H₂O

In this chemical equation, we have that the equation is well balanced and mass is conserved.

A balanced chemical equation is one in which the number of atoms of each elements on the reactant and product sides are the same. In the equation above:

                Reactant side                       Product side

     H:          4 atoms                                   4 atoms

     O:          2 atoms                                    2 atoms

The coefficients offer a way of balancing chemical equations properly.

The law of conservation of mass states that "mass is neither created nor destroyed in an isolated systems where chemical reactions occur". All chemical equations must be written to show the law of conservation of mass. From the equation above, the mass is the quantity of substance that is present in a system, by the balanced chemical equation mass is conserved.

b is the correct

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
