What happens when you mix two different items (gases or liquids) together when they have different densities?
daser333 [38]

Answer:

Density measures how heavy something is for its size. Liquids of different densities can not be mixed and will separate with the heavier densities at the bottom and the lighter densities at the top. The different objects float at different levels in the liquid depending on their densities.

Kc= [3.1*10^-2]^2. (mol/L^2) divide by [8.5*10^-1] [3.1*10^-3]^3 (mol/L)^4​
jok3333 [9.3K]

Answer:

Kc = 12.58

Explanation:

Kc = [0.229]^2*[0.687]^6/[0.221]^4*[0.5685]^3

Kc = (0.052441)(0.10513)/(0.002385)(0.18373)

Kc = 0.0005513/0.000438

Kc = 12.58

Hope that helps!!

What do the coefficients in front of the reactants and products in a chemical reaction represent ?
makvit [3.9K]

It indicates the number of moles of reactants and products

Explanation:

The coefficients in front of the reactants and products in a chemical reaction represents the number of moles of reactants and products.

Every reaction is made up of equal number of moles of reactants and products. Thus, chemical equations are written in such a way to obey the law of conservation of matter.

The numbers used are usually whole numbers and the are very important in stoichiometry.
