Plz help :) The model below shows the equation that represents how hydrogen and oxygen combine to form water.
2H2 + O2 + 2H20

Read each statement below and select all that apply to the equation.

The number of atoms of oxygen in the reactants is different than the number of atoms of oxygen in the product.
The law of conservation of matter is not applied in this equation.
The mass of the reactants is equal to the mass of the products in the reaction.
The total number of each type of atom is conserved in the equation.

for points guys

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

so what is the problem with your lab report and whats the subject of the lab report? i will you
