How is a mixture different from a chemical reaction?

Chemistry
1 answer:
GrogVix [38]3 years ago
5 0

Answer:

A mixture is made when two or more substances are combined, but they are not combined chemically. A chemical reaction is a transformation from one set of chemicals into another set.

Explanation:

A mixture can be homogeneous or heterogeneous, when homo, you cannot see each variable but hey are there. Hetero, means you can see each variable in the mixture. It is considered a mixture and not a chemical reaction because it can be reversed. It will always be able to go back to its separate forms and keep its original composition. When there is a chemical reaction, it is hard to separate and go back to the original variables because there is a molecular bond.

saveliy_v [14]

The equilibrium reaction is

N2O4(g)<----> 2NO2(g)

For reaction

Kp = (pNO2)^2 / pN2O4

Given:

Kp = 0.316

pN2O4 = 3.48 atm

To calculate

pNO2 = ?

0.316 = (pNO2)^2 / 3.48

(pNO2)^2 = 1.0997

pNO2 = 1.049 atm

How does an ion differ from an atom?
Alex73 [517]
An atom is the smallest particle of an element that retains the chemical properties of the element. Atoms are electrically neutral, with a positively charged nucleus that binds one or more electrons in motion around it. An ion-An atom or molecule that has acquired a charge by either gaining or losing electrons. An atom or molecule with missing electrons has a net positive charge and is called a cation*; one with extra electrons has a net negative charge and is called an anion*.

The blank <br> and the blank <br> of atoms are the same on both sides of a chemical equation.
tester [92]

Answer:

Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation.
