Answer:
mixtures can be uniform(called <u>homogeneous</u>) an are known as solutions
Explanation:
Homogeneous mixtures are mixtures with different substances but with uniform composition. E.g. Salt water solution has salt and water inside but the salt dissolves in the water to form a homogeneous mixture.
Answer:
I and IV
Explanation:
Increasing the number of particles at one side of the reaction (H2 in this case) results in the shifting of the equilibrium to the side with lesser number of particles, so in this case the equilibrium will shift to the left (towards the reactants)
A decrease in temperature will always function to favor the exothermic reaction, and since the backwards reaction is exothermic, the equilibrium will shift to the left (towards the reactants).
Option II and V will shift the equilibrium to the products, and adding a catalyst has no effect on the equilibrium.

Subtract the number of electrons from the protons. neutrons have no charge so those don't matter in the formula
Answer:
The science. The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don't react with anything. For this reason they are also known as inert gases
