¿Por qué y cómo la ley de conservación de masa se aplica al universo? ¿Cómo se aplica a las ecuaciones químicas?

Answer 1

Our universe is very large and expanding, so we assume that nothing can escape. As a result, we have a law of mass conservation, which requires us to balance every atom and every molecule in the reaction. This illustrates this law.

For instance...

The beginning:

#"N"_2 + "H"_2 -> "NH"_3#

Maintains nitrogen balance:

#"N"_2 + "H"_2 -> 2"NH"_3#

Equilibrate the hydrogens:

#color(blue)("N"_2 + "3H"_2 -> 2"NH"_3)#
#1*2*"N" = 2*"N" = "2 N"#
#3*2*"H" = 2*3*"H" = "6 H"#

We see two nitrogenous and six hydrogenic elements.

Since nothing can escape from the vastness and expansion of our universe, we have a law of conservation of mass, which is demonstrated by the need to balance every atom and every molecule in the reaction.

As an illustration...

First things first:

#"N"_2 + "H"_2 -> "NH"_3#

Maintain equilibrium among the nitrogens:

#"N"_2 + "H"_2 -> 2"NH"_3#

Maintain equilibrium among the hydrogens:

#color(blue)("N"_2 + "3H"_2 -> 2"NH"_3)#
#1*2*"N" = 2*"N" = "2 N"#
#3*2*"H" = 2*3*"H" = "6 H"#

Six hydrogens and two nitrogens are visible.

Answer 2

La ley de conservación de masa se aplica al universo porque establece que la masa total de un sistema cerrado no cambia con el tiempo, lo que significa que la cantidad total de masa antes de una reacción química es igual a la cantidad total de masa después de la reacción. En ecuaciones químicas, se refleja mediante la conservación de átomos, donde el número y tipo de átomos en los reactivos son iguales al número y tipo de átomos en los productos.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
